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.
