Residential Property Maintenance Guide
This Property Maintenance guide has been developed to assist you in preserving and enhancing the value of your home and the aesthetic quality of your neighborhood.
- Park your vehicles - (including, but not limited to cars, boats, trailers, recreational vehicles, etc.) in the garage, carport, or driveway to ensure public safety, easy trash pick-up, fast access for emergency vehicles, and improved street sweeping, street maintenance, and repair.
- Residents are responsible for the maintenance of parkways adjacent to their property with the exception of trees trimmed by the City. Residents are expected to regularly water parkway trees. To request tree trimming of a parkway tree, contact the Community Services Division at 909.839.7060. Parkways must be maintained free of trash. Grass and plants must be maintained.
The purpose of the City's property maintenance requirements are to preserve property values while assuring a clean and attractive community. Residents are encouraged to maintain attractive homes that have a positive effect on the overall appearance of your neighborhood.
The City's Neighborhood Improvement Officers proactively investigate Municipal Code violations. Commercial and industrial areas in Diamond Bar are also encouraged to maintain attractive places of business.
