For graffiti removal in the unincorporated areas of the Los Angeles County, you may contact our Graffiti Hotline at (800) 675-4357. Our graffiti removal hotline is available with live operators 24 hours a day seven days a week. We strive for a 48-hour response when calls are received via our hotline. In order for us to respond in a timely manner, please answer the brief questions our operators may ask you.

Often questions may be related to graffiti on property which is not the responsibility of the Los Angeles County. For example, we offer information for the agency providing graffiti removal services to the following: Parks and Recreation, Caltrans, Metropolitan Transit Authority (MTA), Metrolink, United States Post Office, Southern California Edison, and the 88 Cities within the Los Angeles County.
