The City contracts with the Inland Valley Humane Society to address and/or enforce barking dog complaints per Diamond Bar Municipal Code Sections 6.08.1260 - 6.08.1320. Refer to the Code for information on how barking dog complaints are filed and investigated.
In the mid-1980s when developers were building houses in certain Diamond Bar neighborhoods, they approached the County of Los Angeles for approval and assistance with creating assessment districts, as authorized by State law, to fund the maintenance of private and public areas that afforded special benefit to nearby property owners. Three such assessment districts were formed by the County and developers, and the administration of the maintenance contracts was taken over by the City when it incorporated in 1989.
Assessments upon the benefited properties are collected by the Los Angeles County Assessor’s Office through property tax bills.
Unlike a tax which funds projects or services of benefit to the general public and may only be used for a public purpose, assessments are used to pay for services that confer a special benefit to specific property owners and are used to pay for the maintenance of both private and public property solely within the defined district boundaries.
Primarily, the City contracts with a private contractor to perform basic weekly, monthly and annual landscape work that includes the mowing of grass, the trimming shrubs and trees, the cutting back of brush from adjacent open space for fire safety, and the clearing of leaves and other debris and trash from drainage ditches (V-ditches) to prevent erosion and flooding. Some areas are also irrigated or hand-watered. In District No. 39, there are five (5) mini-parks that are also maintained. In all, work funded by assessments is aimed at keeping the neighborhoods attractive, reducing erosion, and limiting dangers from wildfires.
State law requires all assessment funds be deposited into a special account and only used to fund the maintenance of district areas as permitted by the assessment district’s original formation. No funds from these assessments can go into the City’s General Fund. Additionally, the City is required to put the maintenance contract out for competitive bidding and award the contract to the lowest responsible bidder, and assessment expenditures are subject to annual audits. Also in keeping with State law, every year an independent report must be generated to verify the assessment expenditures are aligned with the maintenance costs, and the City Council must approve the assessment during one of its regularly scheduled public meetings.
The assessments to fund the costs of maintaining the districts have not been increased above the rates in place 30 years ago. It comes as no surprise that maintenance expenses have gradually increased over the years and today exceed the revenues from the assessments. For at least the past 10 years the City has subsidized the maintenance of the districts using its General Fund. The intent of the assessment districts when they were formed was for them to be self-supporting, which is no longer the case. The General Fund subsidy has grown to a significant amount and diverts money that can be invested in other services such as law enforcement and park and street maintenance.
An independent Engineer’s Report was prepared to outline the method of apportioning the assessments which calculates an amount that is proportionate to the special benefit any given parcel will receive from the district improvements.
The proposed rates for the new District are as follows:
These assessments will replace the existing assessment, they are not combined.

At one time, County and City government agencies had the authority to increase assessments as needed to keep up with expenses by a vote of their respective governing boards. This changed in 1996 when voters approved Proposition 218 which, among other things, changed the law to require that any new assessments or increases for existing assessments be approved by property owners through a mail-in ballot process. This voting process costs money and is time consuming for both the City and property owners. The City held off taking this route for more than 10 years, but has reached a point where the General Fund can no longer sustain the level of subsidy.
Property taxes fund a wide range of government programs and services, with the largest portion going to public schools. The City only receives about 5.2 percent of property tax revenue which goes toward funding citywide services that include public safety, road and traffic improvements, park and public facility maintenance and enhancements, and general administrative services.
Several neighborhoods in Diamond Bar maintain private common areas and landscaping along streets by way of a homeowner’s association. These associations collect fees from the property owners to pay for the costs of maintenance. At least from the standpoint of common maintenance, assessment districts perform a function similar to that of a homeowner’s association.
Homeowner’s associations are common for condominiums, and the fees they collect go toward paying for the upkeep of communal areas within the complex such as swimming pools and picnic areas. Assessment revenues, on the other hand, fund maintenance of landscaped areas such as slopes and greenbelts.
Everyone who owns property within the districts’ boundaries can vote. This includes property owners who do not live in the area since they pay property taxes. As required by State law, all returned ballots will be counted and weighted according to the proportional benefit received and assessment paid by each property owner. The outcome of the ballot proceeding will depend on whether the majority of ballots returned are in favor or opposed.
The City anticipates the ballots will be mailed on May 31, 2019. You should find them in your mailbox soon afterward. You will have until July 16, 2019 to fill them out and return them to City Hall. You may mail them back, drop them off at the City Clerk’s office or bring them to the public hearing on the evening of July 16 and give them to the City Clerk. In any case, all ballots must be received prior to the time the City Council closes the public hearing on July 16.
There are several options that the City considered prior to initiating the assessment ballot proceedings to give property owners in their respective districts the opportunity to decide whether or not to approve the assessment increase to cover their district’s maintenance needs. Should the assessment not be approved, other options that may be considered include: (1) reducing the level of maintenance service; (2) detaching some of the more expensive portions of the assessment district, which would mean the property owners would have to take over the maintenance themselves; or (3) entirely dissolving the assessment districts, which typically leads to an existing or new homeowner’s association taking over maintenance of the private properties and passing along the cost to property owners through monthly or annual fees.
The assessment will provide for adjustments, based on the consumer price index (CPI) and not to exceed 3 percent per year, so that it keeps pace with maintenance costs. However, per State law, assessments will not exceed maintenance costs and the CPI adjustment will only apply if there is an increase in the cost of service. Also, the assessments, whether increased or not, will be approved annually by the City Council as part of one of its regularly scheduled public meetings.
Proposition 218 requires property owners pay their share of the maintenance costs to the extent each property owner is benefited and therefore any exemptions or discounts on assessments for seniors or low income are not allowed.
When your neighborhood was being built in the mid-1980s, the developer and the County agreed to create an assessment district as authorized by State law. Its function is to maintain certain private properties that are of special benefit to property owners within the assessment district and to fund such maintenance by way of an annual assessment on the properties benefitted. This assessment is collected as part of your property tax payment. The revenues from the assessments fund the maintenance of landscaping and park facilities within the assessment district. Three such assessment districts were formed by the County and developers, and the administration of them was taken over by the City when it incorporated in 1989.
District is bounded by Pathfinder Road to the north, Brea Canyon Cutoff to the south, and SR 57 to the east. It comprises 544 parcels, 12 acres of slopes, 3 acres of brush. PDF Map
When the assessment district was formed, it was intended to be self-supporting, and the City Council had the authority to increase assessments each year to keep up with rising costs. However, Proposition 218 (1996) stripped that authority away and put it in the hands of property owners through a ballot process. As a result, assessment rates have not been increased for over 25 years even though cost of maintenance has. For more than a decade the City has subsidized the maintenance of the neighborhood districts by contributing money from its General Fund. The subsidy has grown to a point where it is becoming a significant drain on the City’s finances and the City has determined it can no longer sustain that subsidy level. The purpose of the vote is to once again make the assessment districts self-supporting as originally intended by increasing the assessments to property owners to align with the costs of maintenance.
Up until 1996 the City had the authority to increase assessments as needed to keep up with expenses by a vote of the City Council. But in 1996 voters approved Proposition 218 which, among other things, changed the law to require that any increases in assessments be approved by property owners through a mail-in ballot process. The mail-in ballot process is time-consuming for both the City and property owners and comes with its own costs, so the City held off asking residents to approve an increase. The point has been reached now where the City can no longer justify or afford the amount of the subsidy.
Primarily the City contracts with a private contractor to perform basic weekly, monthly and annual landscape work such as mowing grass, trimming shrubs and trees, clearing brush from adjacent open space for fire safety, and keeping drainage ditches clear of debris to prevent erosion and flooding. Some areas require regular watering to stay healthy. Overall, this work is aimed at keeping the neighborhoods attractive, reducing erosion, and limiting dangers from wildland fire.
The proposed assessment for your property for fiscal year 2021-22 is printed on the Official Ballot included with the notice and information item. The new assessment rates by property type are as follows:
The method used for apportioning the assessment is based upon the proportional special benefits to be derived by the properties in the assessment area over and above general benefits conferred on real property or to the public at large. The apportionment of special benefit is a multi-step process: the first step is to identify the types of special benefit arising from the improvements or services, the second step is to estimate the general and special benefits, and the third step is to allocate the assessments to property based on the estimated relative special benefit for each type of property.
In order to determine the assessments, each property was assigned an estimated level of special benefit relative to a single family home. The method of benefit determination is based on the type of property and its size. After the level of benefit for each property was estimated, the total cost of the Landscape Assessment District Improvements to be funded by the proposed assessments was allocated to each property based on the estimated special benefit received.
An engineer’s report describing the proposed improvements or services, method of assessment, budget, benefits and proposed assessment for each parcel is available on the City’s website at www.diamondbarca.gov/41218
For more information, contact the Public Works Department-Engineering at (909) 839-7040.
The City is proposing to establish the assessment so that it keeps pace with increasing costs in maintenance by including a consumer price index component which would be capped at 3% per year. However, every year the City must do a report to justify any proposed increase. Assessments may only be increased if costs increase and all assessments, whether increased or not, must be approved by the City Council annually at a public meeting and the amount cannot exceed the cost of providing the service.
State law requires that any assessment funds be deposited into a special account, and they can only be spent on costs incurred in maintaining the assessment districts as permitted under the assessment district’s original formation. In addition, the properties cannot be assessed for any more than what it costs to perform such maintenance. As noted above, each year an independent report must be generated that verifies the assessment is aligned with the costs and each year the City Council must approve the assessment at a noticed public meeting. In addition, the City is required to put the maintenance contract out for competitive bidding and by State law, must award the contract to the lowest responsible bidder. No funds from these assessments can go into the City’s General fund, and they are subject to annual audits.
The City Council dissolved the existing District No. 41 on May 4, 2021, so there will be no more revenue in future years from that previous funding source. The proposed District No. 41-2021 would replace that old district with enough revenue to continue providing services the neighborhood is accustomed to. If the proposed assessment is not approved, the responsibility for all the landscaping work previous done by the City will fall on the shoulders of individual property owners or collectively on the various homeowners’ associations in the neighborhood. If the responsibility falls to a homeowners' association, this may cause some property owners HOA dues to increase. Property owners are encouraged to contact their HOA for more information.
Everyone who owns property within the boundaries of the districts can vote. This includes property owners who do not live in the area. Since property owners pay the assessments when they pay property taxes, State law requires that property owners vote on the assessment. The assessment will be considered approved if the number of mail-in ballots approving it exceed the number of mail-in ballots opposing it. As required by State law, ballots are weighted based upon the amount of assessment paid by each property owner.
Please follow these steps to complete the ballot:
1. Verify that the owner name, addresses, and parcel number(s) listed on the ballot are correct. If they are not correct, please telephone the City of Diamond Bar at (909) 839-7000. (If something is incorrect, find out from the caller what information is not correct and include this on your e-mail-form log to SCI.)
2. Mark or completely fill in the oval next to the word “YES” or “NO” to approve or disapprove of the proposed assessment. You may use a pencil or pen. Be sure to fill in only one oval, otherwise, your ballot may be disqualified.
3. Sign and date the ballot. After making your vote, simply FOLD the ballot so that your vote is on the inside of the fold. Then place the ballot in the return envelope provided and seal the envelope. No postage is necessary. Please see the response to the next question below for more information on how to return the ballot.
4. If you make a mistake in completing your ballot or wish to change or withdraw your ballot, please submit a request by mail to the City of Diamond Bar, at 21810 Copley, Diamond Bar, CA 91765; or in person at the same address, or by calling (909) 839-7000.
You may return your ballot in either of the following ways:
1. Mail it to the address shown in the enclosed, postage-paid return envelope so it is received on or before July 6, 2021.
2. Deliver it in person
a. By July 6, 2021, 5 p.m. to the Diamond Bar City Clerk, at the Diamond Bar City Hall located at 21810 Copley Drive, Diamond Bar, CA.
b. On July 6, 2021 after 5 p.m. and before 6:30 p.m. (and previous to the close of the public input portion of the public hearing) to the Diamond Bar City Clerk, at City Hall, located at 21810 Copley Drive, Diamond Bar, CA.
3. Deliver it in person to the public hearing which is scheduled to begin at 6:30 pm on Tuesday, July 6, 2021, at the City Hall, Windmill Room, First Floor located at 21810 Copley Drive, Diamond Bar, CA.
Only official ballots that are signed, marked with the property owner’s support or opposition, and received by the deadline will be counted. Ballots will be tabulated under the direction of the City Clerk (Tabulator) on July 6 after the last call for ballots, at the conclusion of comment period of the Public Hearing. The results of the balloting are expected to be announced at the same City Council Meeting.
The City Council will not impose the assessment if there is a majority protest. A majority protest exists if, upon conclusion of the ballot tabulation, ballots submitted in opposition to the assessment exceed ballots submitted in favor of the assessment. Ballots shall be weighted according to the proportional financial obligation of the affected property.
Each ballot is weighted by the amount of assessment it represents. In other words, if one property owner of a home receives a ballot for $525.22 in proposed assessment, and another property owner of a condominium receives a ballot for $483.21 in proposed assessment, the first property owner’s ballot will count for approximately 1.1 times that of the second property owner because the first property owner’s ballot is for a larger proposed assessment amount.
To request a replacement ballot, contact the City Clerk's office at (909) 839-7000 and provide the following information:
Replacement ballots will be mailed to the name and address listed on the Los Angeles County Property Assessor records. If requesting to be mailed to different address, proof of ownership must be submitted. Proof of ownership may include property deed, title report or settlement statement (HUD).
To report incorrect information contained on your ballot, contact the City Clerk's office at (909) 839-7000.

Note: Request must be received before the conclusion of the comment period of the City Council meeting public hearing on July 6.
Yes. Please perform the following two steps to change your vote:
If you own property in an area that has an existing homeowners association you may be paying fees to the HOA for maintenance of property and facilities that are not part of the assessment district’s responsibility. Typically, the HOA fees would be for common areas within a condominium complex.
Property taxes fund a wide range of governmental services and the largest portion of the property tax revenue goes to fund public schools. The City only receives about 5.2% of the property taxes you pay, and that goes for supporting various City-wide functions including police services, street maintenance and improvements, park maintenance and improvements, maintenance of other public facilities, and general administrative services.
Several neighborhoods in the City maintain private common areas and landscaping along streets by way of a homeowner’s association. These HOAs collect fees from the property owners to pay the costs of maintenance. From the standpoint of common maintenance, assessment districts perform a function similar to that of an HOA.
Proposition 218 requires that property owners pay their share of the maintenance costs to the extent each property owner is benefitted and thus, forbids any exemptions or discounts on assessments for seniors or low income.
Dissolution means the Landscape Assessment Districts (Districts) will cease to exist, at which time responsibility for the maintenance of the district will be turned over to property owners.
Dissolution is being considered because, for several years now, the assessment revenue generated in both Landscape Assessment Districts (Districts) has been insufficient to cover even the bare essential level of landscape maintenance and related services needed.
Districts are meant to be self-supporting through assessments on properties that benefit from the services provided. The annual assessment amounts of $236 per parcel in District 39 and $220.50 per parcel in District 41 were established upon their formation in 1985 and have never been increased.
For more than 10 years, the City has used Diamond Bar General Fund dollars to subsidize the budget shortfalls in each District which placed added strain on the City’s limited resources and diverts funds needed in other areas of benefit to the greater community such as public safety, road and park maintenance.
In order to help make the Districts financially viable again, the City conducted a mailed ballot proceeding in summer 2019. The ballot asked District property voters whether or not they would support an assessment increase. The majority of ballot respondents opposed the increase.

Prior to the July 1 transition, it is suggested that property owners become familiar with their maintenance responsibilities and review the following:
Property owners may make changes in accordance with City landscape and construction regulations. Contact the Planning Division for additional details by submitting an inquiry form.
Yes, property owners may remove trees on their properties. As a reminder, Diamond Bar is home to many protected species of trees, including Sycamore, Oak, and Black Walnut, and property owners should verify the species prior to removal.
A complete grid trim of the trees located within the districts is not scheduled for this fiscal year. Property owners may request trimming or maintenance of trees that may pose a health and safety issue by contacting the City’s Public Works Department at (909) 839-7060 or www.diamondbarca.gov/report
The City will continue to maintain the five mini-parks and trails after the July 1, 2021 dissolution.
No, all irrigation equipment will remain but City utility accounts, (water and electricity), will be closed effective June 30, 2021.
The City maintains trees located within parkways and medians.
The final day the City will maintain the landscaped areas located on private property within the districts will be June 30, 2021.
No, this is not public information.
The City’s Neighborhood Improvement Division is responsible for ensuring property owners adhere to all City maintenance guidelines. Residents are encouraged to report unmaintained areas to the Neighborhood Improvement office at (909) 839-7030 or www.diamondbarca.gov/report
Upon dissolution, the property tax assessment will no longer be charged, starting with the 2021-22 fiscal year. Property owners must contact their Homeowners Association for fee information.
All scheduled maintenance will be completed prior to dissolution. No new vegetation will be planted, as this is not included in the current fiscal year budget.
For the current fiscal year of 2020-2021, a total of $264,981 was budgeted for District 41 and $375,748 for District 39.
The beverage container recycling program began in California in 1987 as a way to assure the return for recycling of a greater percentage of the beverage containers sold in the state. It is estimated that more than 300 billion aluminum, glass, and plastic beverage containers have been recycled since.
Any product sold in a container that is not aluminum, glass, plastic, or bimetal is excluded from CRV. These include:
A recycling center is an operation certified by the Department to accept empty beverage containers and pay CRV to consumers. Recycling centers are operated by independent businesses, not the State of California.
Currently, state certified recycling centers pay a minimum of $1.65 CRV for aluminum cans; $1.31 CRV for clear PET plastic bottles; $0.58 CRV for HDPE plastic bottles (similar to the large water jugs); and $0.10 CRV for glass bottles. These CRV per pound rates are periodically adjusted, with new rates taking effect January 1 and July 1.
Yes, if the material is contaminated. Operators of certified recycling centers must inspect each load of containers to determine whether it is eligible for CRV. Recycling centers have the option to refuse to accept containers which, in their opinion, are excessively contaminated with dirt, moisture, or other foreign substances.

All individuals and businesses doing work within city limits, whether or not they have a physical structure in the city, are required to have a business license. This includes contractors, internet and home-based businesses. Refer to the Business License webpage to download the business license packet or contact the Planning Division for more information by calling (909) 839-7030 or emailing firstname.lastname@example.org.
You may mail in the application along with a check to the address noted on the application, submit online through the Planning Inquiry form, or make an appointment with the Planning Division at www.diamondbarca.gov/appointment..
Once an application is received, a staff member will contact you if additional information is required; otherwise, the business license certificate and receipt will be sent to the email address provided on the application. Please allow a few days for processing.
The basic business license fee is $14 per year. Licenses requiring a one-time zoning clearance (PDF) are $77.91, and an additional fee of $320 per individual requiring a background check. All fees are due when the application(s) are submitted, and are non-refundable and non-transferable. Businesses that require background checks include: acupressure and massage establishments, alarm companies, and sales of alcoholic beverages for offsite consumption.
Once you have provided your completed application with appropriate payment, it takes an average of 5 working days to process and issue a basic business license, and may take up to 30 days for those requiring a zoning clearance. Licenses requiring background check(s), the process may take up to 90 days. If for any reason your application is not approved, you will be notified within these time frames.
Applications may need to be reviewed by other departments and government agencies including, but not limited to:
You will be notified if additional permits, approvals, or fees are required.
This may be filed with any local newspaper, such as the Daily Bulletin, Highlander or San Gabriel Valley Tribune.
Yes. Licenses are not transferable. Relocation, expansion, change in owner, change in name, change in type of business, all require a new business license application and fee(s).
Business licenses are valid for one year and must be renewed annually. Any person who fails to renew their license on or before the renewal date shall be deemed to be operating without a license, and will be subject to delinquent fees that double each thirty-day period. Renewal fees are $14 for basic licenses. Additional fees may apply for those applications requiring substantial changes and/or background check.
It is the business owner’s responsibility to notify the Planning Division if you have closed your business. Your account will remain active until notification is received and you will be responsible for all accrued penalties.
In order to operate, maintain, or work in a massage establishment within Diamond, individuals must possess a current California Massage Therapy Council (CAMTC) certificate and CAMTC-issued identification card. Copies of both the certificate/renewal and ID card must be submitted to the City when applying for a massage establishment business license. A background investigation will be conducted as part of the application process. Additional information, including permit requirements and restrictions as well as requirements for the operation and maintenance of the massage establishment premises and equipment can be found on Sec. 5.08.070 of the Diamond Bar Municipal Code.
No, applications will not be prioritized in any way. All applications submitted within the two-day filing window of 9 a.m. on Monday, June 22 to noon on Wednesday, June 24 will be entered into the lottery.
As soon as the application window closes at noon on June 22, all applications will be placed into a pool and 64 will be randomly drawn.
A team of City staff members will promptly call all business owners whose applications were drawn. It should be noted, however, that being selected in the lottery does not guarantee that a grant will be issued to the applicant. City staff will verify the eligibility of each application and contact the business owners if additional documents are needed.
Once approved, business owners will be provided grant funds in one lump sum. Proof of payment for eligible expenses will need to be submitted to the City on a quarterly basis or until all grant funds have been spent.
Grant funds must be used to cover essential operating expenses (e.g.rent, utilities and payroll) or costs related to reopening safely such the purchase of personal protective equipment (e.g. masks, gloves, aprons or gowns, goggles and face shields) or products or materials to assist with infection prevention and physical distancing (e.g. plexi-glass guards, signage and floor markers)
No. The grant does not have to be repaid, however, any funds not spent within one year of receipt must be returned to the City.
To maximize the impact of the limited funds available, at this time the Business Recovery Program grant is only open to businesses that were required to close or reduce operations under the Governor’s and County Public Health Department orders. Home-based business owners perform activities from their own homes and therefore are not heavily dependent on in-person services or transactions nor do they have to pay rent, utility, wages, and other related expenses associated with maintaining a physical storefront and having a workforce.
Because the tax status and circumstances are unique to each business, grant recipients should consult their tax professionals to determine what, if any, tax obligations will result from receiving this grant.
Yes, you must employ a minimum of one employee and no more than 25 full-time or full-time equivalent employees. The phrase full-time equivalent refers to a combination of part-time employees whose combined hours are the equivalent of a full-time position. For example, two employees who each work 20 hours per week are equal to one full-time worker.
A low-to-moderate job is one that pays a salary less or equal than 80 percent of the low-moderate median household income as defined by the federal Community Development Block Grant (CDBG) program. This depends on the number of persons in the employee’s household. For a single individual, the low to moderate income level is at or below $63,100 annually; 80 percent of this amount is $50,480. For maximum income limits for households of more than one person, refer to the 2020 CDBG income guidelines for Los Angeles County, see Business Recovery Program policy for income details.

The Neighborhood Improvement Officers enforce all City Municipal Codes applicable in the community, including the provision against the open storage of junk. This code states that front and side yards shall be kept and maintained free and clear of:
If a property is found not in compliance with the code, a notice of violation is sent to the owner allowing a certain number of days to correct the violation. If a violation is not corrected within the time allowed, the owner may be fined. Any debris that is found, which is associated with the code violation, may be removed by a contractor at the property owner's expense. Failure to pay the fine will result in a lien being placed against the property. For more information, call 909-839-7030 or submit a request.
The City's Municipal Code states that exterior holiday lights and decorations must be removed within 30 days of installation, and no later than mid January. Besides contributing to blight, keeping holiday lights installed for an extended period of time creates the potential for a fire hazard because of their temporary-use nature. Homeowners found not to be in compliance will be issued a courtesy notice to correct violation within 10 days. Failing to remove the lights within the allotted time frame can result in a $100 fine.
Yes. All vehicles that are being repaired, dismantled, or incapable of operating are considered "inoperable" and must be stored out of public view, such as in the garage, when possible. It is considered a violation of the City Code if the vehicle or its parts become a hazard to the public health and safety. To report, contact the Neighborhood Improvement Division at 909-839-7030.

Short-term rentals, such as those listed on Airbnb and similar sites, are prohibited in all residential zones within Diamond Bar. The Diamond Bar Municipal Code defines a hotel or motel as “facilities with guest rooms or suites, provided with or without kitchen facilities, rented to the general public for transient lodging (less than 30 days).” By definition, a residence being rented to a tenant for fewer than 30 days is, therefore, classified as a hotel/motel, and is not a permissible use in residential zones pursuant to the City’s land use table. For more information, refer to Sec. 22.08.030. and Sec. 22.80.020. of the Diamond Bar Municipal Code.
The Diamond Bar Zoning Map designates existing land use classifications for each parcel located within the city. In addition to land use types (residential, commercial, and open space/conservation), the map also indicates the density of housing development allowed such as Low Medium Density Residential (RLM), Medium High Density Residential (RMH), and High Density Residential (RH). The Zoning Map is available online as part of the City’s GIS mapping database. To view the Zoning Map, click the Layers List icon on the top right corner and select “Zoning.” For more information, contact the Planning Division at (909) 839-7030 or firstname.lastname@example.org.

State law requires each city to adopt a comprehensive, long-term General Plan for its physical development. General Plans include several “elements” that address various topics. The Diamond Bar General Plan was comprehensively updated in 2019 and includes the following elements:
While most portions of General Plans typically have a time horizon of 20-25 years, State law requires that the Housing Element be updated in 8-year “cycles.” The City is currently preparing a Housing Element update for the 2021 to 2029 planning period, which is referred to as the “6th Housing Element cycle” in reference to the six required updates that have occurred since the comprehensive revision to State Housing Element law in 1980.
 California Government Code Sec. 65300 et seq.
 The Housing Element was last updated in 2014 and was not part of the 2019 General Plan update
The State Legislature has delegated to the California Department of Housing and Community Development (“HCD”) the authority to review Housing Elements and issue findings regarding the elements’ compliance with the law. When HCD issues a letter finding that the Housing Element is in substantial compliance with State law it is referred to as “certification” of the Housing Element.
Housing Element certification is important for two main reasons:
 California Government Code Sec. 65585
 California Government Code Sec. 65589.3.
 AB 101 of 2019
The major issues that must be addressed in the Housing Element are: 1) how City policies, plans and regulations help to meet the region’s housing needs for persons and families of all income levels; and 2) how City land use regulations accommodate the special housing needs of those with disabilities or other difficulties.
Reasonable accommodation for persons with disabilities
Emergency shelters and other facilities serving the homeless
Large (5+) families
 California Government Code Sec. 65583
 California Government Code Sec. 65583(a)(5)
By definition, housing is considered “affordable” when total housing cost, including utilities, is no more than 30% of a family’s gross income. State law describes five income categories, which are based on county median income as shown in Table 1.
Table 1. Household Income Categories
% of county median income
Up to 30%

Affordable housing costs for all jurisdictions in Los Angeles County are determined based on these income categories as shown in Table 2. These incomes, rents and housing prices are based on a 4-person family and are adjusted for different family sizes.
Table 2. Income Categories and Affordable Housing Costs – Los Angeles County

Each California city is required to plan for new housing to accommodate a share of regional needs. The Regional Housing Needs Assessment (“RHNA”) is the process established in State law by which housing needs are determined.
Prior to each planning cycle the total new housing need for each region of California is determined by HCD based upon economic and demographic trends, existing housing problems such as overcrowding and overpayment, and additional housing needed to ensure reasonable vacancy rates and replace units lost due to demolition or natural disasters.
Diamond Bar is located within the Southern California Association of Governments (“SCAG”) region, which includes Los Angeles, Orange, Riverside, San Bernardino, Imperial and Ventura counties. The total housing need for the SCAG region is distributed to cities and counties by SCAG based upon objectives and criteria established in State law.
In 2019 HCD determined that the total new housing need for the entire SCAG region in the 6th Housing Element cycle is 1,341,827 units. SCAG is currently finalizing the RHNA plan for the 6th cycle, which must fully allocate the total RHNA to jurisdictions in the SCAG region. SCAG expects to adopt the final RHNA plan by February 2021.
The RHNA also distributes each jurisdiction’s total housing need into four income categories (the extremely-low and very-low categories are combined for RHNA purposes). Diamond Bar’s preliminary 6th cycle RHNA allocation by income category is shown in Table 3.

Extremely Low + Very Low

 California Government Code Sec. 65584 et seq.
 California Government Code Sec. 65584(d)
The RHNA allocation identifies the amount of additional housing a jurisdiction would need in order to have enough housing at all price levels to fully accommodate its assigned share projected growth over the 8-year planning period. The RHNA is a planning requirement based upon housing need, not a construction quota or mandate. Jurisdictions are not required to build housing or issue permits to achieve their RHNA allocations, but some provisions of State law establish specific requirements when housing production falls short of RHNA allocations. One such requirement is streamlined review and approval of housing development applications that meet specific standards. Other than requirements for streamlined permit processing, there are currently no legal or financial penalties imposed on cities for failing to achieve their RHNA allocations.
 California Government Code Sec. 65913.4 (SB 35 of 2017)
The Housing Element must providean evaluation of the city’s capacity for additional housing based on land usepatterns, development regulations, other development constraints (such asinfrastructure availability and environmental conditions) and real estatemarket trends. The analysis must be prepared at a parcel-specific level ofdetail and identify properties (or “sites”) where additional housing could bebuilt consistent with City regulations. This evaluation is referred to as the“sites analysis” and State law requires the analysis to demonstrate that thecity has adequate capacity to fully accommodate its RHNA allocation in eachincome category. If the sites analysis does not demonstrate that adequatecapacity exists to fully accommodate the RHNA, the Housing Element must describewhat steps will be taken to increase capacity commensurate with the RHNA –typically through amendments to land use and zoning regulations that couldfacilitate additional housing development. Such amendments typically includeincreasing the allowable residential density or allowing housing to be built inareas that are currently restricted to only non-residential land uses.
Diamond Bar’s new General Plan,adopted in December 2019, estimates that up to 3,750 new housing units could bebuilt in the city by 2040, depending on market conditions. It is expected thatmuch of this growth would occur within the Town Center Mixed Use, NeighborhoodMixed Use, Transit Oriented Development and Community Core Overlay focus areas,while most existing residential neighborhoods will experience less growth andchange. While the General Plan identifies potential for significantly more newhousing than the draft 6th RHNA allocation of 2,514 units, theHousing Element must demonstrate that realistic capacity exists for the amountof new housing in each income category to be built during the 2021-2029 planningperiod based on zoning, site conditions and market trends. This analysis isexpected to be the primary focus of the Housing Element update.
State housing laws are based on the premise that every city has an obligation to accommodate a range of housing types for persons at all income levels. Every community is dependent on a variety of low- and moderate-income workers in jobs such as landscaping, building maintenance, child and elder care, medical technicians, personal services, clerical support and retail trade. While the existing housing stock serves the needs of many residents, market rents and prices are higher than some families can afford. In addition, low-wage jobs have increased at a much faster rate than affordable housing is being built.
While cities are not required to build new housing, they must ensure that their land use regulations encourage a full range of housing types. Rental apartments typically provide the majority of affordable housing, but other types of housing such as accessory dwelling units (ADUs) can also help to address this need. Various governmental programs provide funding assistance for affordable housing, but if a city’s development regulations are too restrictive, affordable housing may be infeasible and the housing needs of the local workforce will be shifted to other cities.
 “Accessory dwelling unit” means an attached or a detached residential dwelling unit that provides complete independent living facilities for one or more persons and is located on a lot with a proposed or existing primary residence. It shall include permanent provisions for living, sleeping, eating, cooking, and sanitation on the same parcel as the single-family or multifamily dwelling is or will be situated. (Government Code Sec. 65852.2(j)(1)
SCAG’s 6th cycle RHNA allocation for the entire 6-county region is 1,341,827 units compared to 412,137 units in the 5th cycle. There are two main reasons why the 6th RHNA allocation is so much higher than the 5th cycle.
First, the 5th cycle RHNA allocation was established in 2012 while the severe economic effects of the “Great Recession” were discouraging growth. As a result, the 5th RHNA was uncharacteristically low. For comparison, SCAG’s 4th cycle (2006-2013) RHNA allocation was approximately 700,000 housing units.
Second, for the 6th cycle the State made a major modification to the process for determining RHNA allocations. In prior RHNA cycles, total housing need was based only on projected population growth. However, for the 6th RHNA cycle the State added existing need to the total RHNA calculation. Existing need includes households that are currently overcrowded (defined as more than one person per room) or are overpaying for housing (defined as more than 30% of gross income).
The total 6th cycle RHNA allocation for the SCAG region is comprised of the sum of existing need and projected need, as follows:
Existing need: 577,422 units \ Projected need: 764,405 units
Total need: 1,341,827 units
As seen from this breakdown, if existing need were excluded (as was the case in prior RHNA cycles) the total need would be similar to the 4th cycle RHNA.
With regard to jurisdictional RHNA allocations, the methodology adopted by SCAG for the 6th cycle places greater emphasis on the proximity of jobs and public transit rather than vacant developable land. As a result, the urbanized areas of Los Angeles and Orange counties are assigned much higher housing need as compared to prior cycles even though they generally have much less vacant land than inland areas.
Diamond Bar’s RHNA allocation in the 5th cycle was 1,146 units; therefore, the draft 6th cycle allocation of 2,514 units is about 2.2 times the prior cycle. By comparison, SCAG’s total 6th RHNA allocation is 3.3 times the 5th cycle total.

Effective July 1, 2020 - AB 827 mandates food service establishments provide customers with bins for three types of waste generated from items purchased and consumed on site – food scraps, recyclables, and trash.
AB 827 applies only to limited-service food establishments such as fast-food restaurants where customers order and pay at the counter and clear their own tables after eating. Full-service restaurants are exempt from this law since they typically have staff separating food waste after clearing tables.
Full-service restaurants are exempt if they they have wait staff and/or kitchen staff responsible for escorting diners to their table, taking their order, delivering their food to their table, bringing their bill or helping them process their payment, and clearing their table after they leave. Bins for employees to sort food waste must be labeled, visible, and readily accessible.
Organic waste bins or containers must be visible and easily accessible to employees and customers, they must be labeled, and they must be placed adjacent to each trash can (restroom waste bins are excluded). There is no minimum number of bins required.
To reduce greenhouse emissions by diverting commercial and multi-family residential organic waste through organics recycling.
Organic waste, as defined in AB 1826, is food waste, green waste, landscape and pruning waste, nonhazardous wood waste, and food-soiled paper.
Composting, mulching, anaerobic digestion, and rendering are examples of ways organic material is processed to create a variety of valuable products.
Permits for garage or yard sales are not required, but residents are asked to hold no more than two per year. Advertising signs may not be posted in the public right-of-way (for example on street signs, street trees, traffic signals, streetlight poles, or inside road medians). Residents may advertise through local publications or by asking neighbors to post signs on their private property. Signs shall not exceed three square feet in area and may only be displayed during the time of the sale. The signs shall be promptly removed at the end of the sale.
The City's Municipal Code states that exterior holiday lights and decorations must be removed within 30 days of installation, and no later than mid January.
Besides contributing to blight, keeping holiday lights installed for an extended period of time creates the potential for a fire hazard because of their temporary-use nature.
Homeowners found not to be in compliance will be issued a courtesy notice to correct violation within 10 days. Failing to remove the lights within the allotted time frame can result in a $100 fine.
Yes. All vehicles that are being repaired, dismantled, or incapable of operating are considered "inoperable" and must be stored out of public view, such as in the garage, when possible. It is considered a violation of the City Code if the vehicle or its parts become a hazard to the public health and safety.
The Neighborhood Improvement Officers enforce all City Municipal Codes applicable in the community, including the provision against the open storage of junk. This code states that front and side yards shall be kept and maintained free and clear of all construction and automotive materials or parts, trash, refuse, debris, inoperative motor vehicles, camper shells, discarded or broken materials, appliances, furniture, junk, equipment or similar materials.
If a property is found not in compliance with the code, a notice of violation is sent to the owner allowing a certain number of days to correct the violation. If a violation is not corrected within the time allowed, the owner may be fined. Any debris that is found, which is associated with the code violation, may be removed by a contractor at the property owner's expense. Failure to pay the fine will result in a lien being placed against the property.
Contact the Neighborhood Improvement Officer at 909-839-7030.
Shopping carts are private property and provided to shoppers as a customer service. Removing them from their respective store parking lot is illegal. Also, carts left on sidewalks or streets create visual blight and pose hazards to motorists, pedestrians, and bicyclists. This makes them a violation of 12.04.140 of the City's Municipal Code that prohibits encroachment within public streets and sidewalks. Report stray shopping carts by completing a request online or calling (888) 992-4778.
Yes. All vehicles that are being repaired, dismantled, or incapable of operating are considered "inoperable" and must be stored out of public view, such as in the garage, when possible.

Any action that is taken in association with correcting the violation will be charged to the property owner. Contact the Neighborhood Improvement Division at 909-839-7030.
By law, you have the right to trim tree branches that extend into your property line. However, it is good practice to bring up the issue with your neighbor first. Give them a chance to take care of the trimming themselves, and/or offer to do it if they prefer.
Keep in mind that California has very strict laws regarding tree trimming. Under section 3346 of the California Civil Code, a person may not cut or remove any part of a tree that does not overhang their property. If you cause the tree to die or cause so much damage that its value is destroyed, you may be held financially responsible. Furthermore, certain trees such as the native oak, walnut, sycamore and willow are protected by Diamond Bar ordinance, even if they are on private property. If the pruning is extensive, you need to first obtain a permit. Refer to Chapter 22.38 of Diamond Bar Municipal Code for more information on tree preservation and protection.

To determine allowable uses on a property, refer to the Land Use Table in Development Code Section 22.08.030 for residential properties and Development Code Section 22.10.030 for commercial, office and industrial properties. Uses listed with a “P” are permitted outright; uses listed with a “CUP” require approval of a conditional use permit; and a dash ( - ) means that the use is not permitted in that zoning designation. Contact the Planning Division at (909) 839-7030 or Planning@DiamondBarCA.gov for CUP application requirements.
Exact location of property lines are determined by a licensed surveyor. The City does not recommend any specific surveyor or survey company. However, you can search for California-licensed professional engineers and land surveyors by visiting the California Department of Consumer Affairs website. For approximate property lines, visit the L.A. County Office of the Assessor’s website for your property line dimensions.
All residentially-zoned properties are eligible to construct one ADU and one Junior ADU (JADU), regardless of lot size.

The City Council is considering placing athree-quarter cent local sales tax increase (also known as a “transactions anduse tax”) measure on the November 3, 2020 ballot for consideration by thevoters. The measure, which requires a majority vote of the Diamond Bar voters,would provide a reliable, ongoing source of local revenue to fund essentialcity services like public safety, parks and recreation facilities and programs,and street maintenance.
The City is experiencing concerning revenue trends as the cost of doing business continues to rise. There are a number of contributing factors, including:
A three-quarter cent sales tax increase isestimated to generate approximately $3.8 million annually.
The sales tax revenues could be used to address any community priority, including but not limited to:
No. Absent a Statewide legislative change, allrevenues generated by the sales tax measure remain under the control of theCity and used only for local needs and priorities.
Yes. As they have done recently with Measure M (transportation) and Measure H (homelessness), the County or other regional agency could place a sales tax measure on the ballot to increase the sales tax in the City. That money would go to the County or other regional agency and potentially none of it spent to directly benefit Diamond Bar. A County sales tax measure could be imposed in Diamond Bar even if a majority of Diamond Bar voters voted against it.
Generally, state law caps sales tax rates at 10.25 percent in the City. The current City rate is 9.5 percent. If Diamond Bar voters were to enact the local 0.75 percent sales tax increase, the local rate would be capped and no further local sales tax increases could be applied to Diamond Bar.
Yes. All funds generated from the measure would be subject to the City’s annual independent audit to verify proper expenditure. Regular reports evidencing the expenditures would be publicly available.
Yes. Voters in many Southern California cities voted in favor of enacting local sales tax increases in recent years, including, but not limited to:
The City has historically spent within its means, approving balanced operating budgets and using banked reserves to complete capital projects like the Diamond Bar Center, City Hall & Library, and various maintenance projects throughout town. The City’s decision to operate with a contract services model keeps staffing levels modest (less than one city employee per 1,000 residents) and associated pension costs down. The City has also taken proactive steps to reduce pension liability through additional annual payments and contributions to a Section 115 Trust to reduce Other Post Employment Benefits (OPEB) liability.
No, it is illegal to possess, transport, discharge, or sell fireworks within the city of Diamond Bar. For details, view the Diamond Bar Municipal Code Chapter 16.04
All trash cans must be kept out of public view at all times. (Exception will be made on the evening prior to, and/or the day of your trash pick-up.) Rear yard storage of trash receptacles shall be screened by approved walls or fences from view of neighboring property, public and private streets, and public and private right-of-way.
For bulky item pickup, contact your waste hauler. Single family residences may contact Waste Management at 909-599-1274 and multi-family residences may contact Valley Vista at 800-442-6454.
If the tree is planted on public property, a work order can be generated by submitting an online request through the City’s Report a Concern portal. Once received, City staff will inspect the tree to determine if it meets the criteria for trimming. Inspection findings will be shared with the reporting individual. The City does not maintain backyard trees or trees on private property.
Water leaks on private property such as shopping centers or multi-family complexes are the property owner’s responsibility, and can be reported to the Walnut Valley Water District at (909) 595-7554. If the water leak is occurring in a city park, street median, or public slope, notify the City’s Public Works Department by calling (909) 839-7060.
Maintenance of the city’s storm drains fall under the purview of the Public Works Department. If you accidentally drop your keys or other object in a storm drain inlet and they are within view, you can inquire with the Public Works staff for retrieval assistance by calling (909) 839-7060.
In addition to organics recycling, SB 1383 also require businesses to implement an Edible Food program to prevent throwing out "edible food".
SB 1383 regulations apply to all persons and entities that generate organic materials, such as food scraps and plant trimmings. Everyone is required to divert their organic materials from the garbage. In addition, certain entities that provide food will be required to donate their excess food to feed people.
Commercial entities and education agencies may be exempted from some or all of the requirements if they can provide documentation or evidence that shows minimal organic material is being generated or if their premises lack adequate space to fit all three containers (garbage, recycling, and organics). For more details, visit: https://calrecycle.ca.gov/organics/slcp/waivers.
As the most aggressive waste reduction law to be adopted in California in the past three decades, SB 1383 includes significant penalties for non-compliance including monetary penalties. Penalty amounts vary depending on the jurisdiction and extent of non-compliance, but the base penalties shall fall within the ranges listed below.
Report for Reward is a City of Diamond Bar program that offers individuals financial incentive of up to $500 for providing information leading to the arrest of a person(s) who damaged property as a result of a realized (or attempted) residential or vehicular burglary within Diamond Bar city limits.
Report for Reward was established on November 15, 2013 after being approved by the Diamond Bar City Council – by way of Ordinance No. 08(2013) – during its regular meeting of October 1, 2013.
Ordinance Number 08(2013) is now part of the Diamond Bar City Municipal Code – Chapter 9.02 entitled: “Reward for Crime Information.” The City’s Municipal Code is available for viewing online or in person at Diamond Bar City Hall during its regular business hours of Monday through Thursday 7:30 a.m. to 5:30 p.m., and Friday from 7:30 a.m. to 4:30 p.m.
Everyone is encouraged to report property crime-related information or any suspicious activity to the Walnut-Diamond Bar Sheriff’s Station. However no City employee or employee of the Los Angeles County Sheriff’s Department shall be eligible for a monetary reward under this program.
The majority of burglaries happen on weekdays during daytime hours when most people are away from their homes – either at work, school, or running errands. Suspicious activity that should be reported includes unfamiliar persons on foot, bicycle, or vehicle driving through residential streets below the speed limit or lingering in an area, seemingly without a purpose.
When calling the Sheriff’s Station at 909-595-2264 (9-1-1 if it’s an emergency), try to provide as much as information as you can about what you are observing (description of the individuals, and the car color, make, model and, if possible, license plate number).
The dispatcher will take down your contact information, and if your tip leads to the identification and arrest of a person or persons suspected of damaging personal property as a result of a burglary incident, the Sheriff’s Station will then forward a recommendation for reward disbursement to the Report for Reward Committee.
The Report for Reward Committee consists of the Diamond Bar City Manager or designee and a sworn member of the Sheriff’s Department.
The committee members will consider and verify the Sheriff’s Department recommendation and ensure that the information provided was directly relevant to the identification and arrest of the suspect(s), and that there was damage to real or personal property as a result of the burglary incident.
The Report for Reward Committee reviews each recommendation carefully and determines the reward amount based on the specific characteristics of the incident, including how much weight the tip carried in locating and arresting the burglary suspect, and the value of the property damaged.
Get to know your neighbors and watch out for each other’s property. The more eyes you have looking for suspicious or criminal activity, the better protected you are your neighbors will be against burglaries. If you are not already a member of Neighborhood Watch, consider joining or starting a group in your area by calling Community Relations Deputy Aaron Scheller at 909-839-7079.

In September 2021, the Diamond Bar Village Homeowners Association hired a California licensed engineer to visually inspect the condominium property and they found a number of issues that are a safety concern and which they detail in a report. The City’s building inspectors and code enforcement officers have been on site and reviewed the report and agree with the engineer’s recommendation of more thorough inspection and testing, as well the installation of temporary roof supports.
The tag colors rate occupancy risk, with yellow indicating medium risk and red indicating high risk:
Regardless of tag color, the condominiums must be vacated in order to keep residents out of harm’s way, and for the engineers and inspectors to safely assess and test all areas of concern, and determine what repairs are necessary.
You should collect essential personal belongings and vacate your condominium as soon as possible. However, on October 11, 2021, the City put the Enforcement of Order to Vacate on hold pending further structural investigations and hearings on appeals.
If you are a renter, you are entitled to relocation assistance from your landlord under California Health and Safety Code Sections 17975-17975.10.
