Graffiti Abatement Program


The mission of the Graffiti Abatement Program is to beautify the City by preventing and removing graffiti.  The program emphasizes a community approach to short term blight removal and graffiti abatement.  The involvement by Half Moon Bay residents in the anti-graffiti movement is key to the long term success of the program.

To report graffiti vandalism in progress, residents should call 911. If you want to report information about “taggers” anonymously, please call the HMB Sheriff Sub Station at (650) 726-8288.

When reporting graffiti, the following should be included:


  • If graffiti is on your property, remove it as soon as you have photographed it and reported it.
  • When graffiti is on a painted surface, the best course of action is to cover it with paint. Before painting over the graffiti, make sure it is reported and photographed. First put a primer coat over the graffiti and follow up with a coat of exterior paint.
  • The rules to protect water quality must be followed. Updated National Pollutant Discharge Elimination System (NPDES) removal requirements are available in the Graffiti Abatement Frequently Asked Questions


Municipal Code Section 15.26.030 B makes it unlawful for an owner of a lot or parcel to allow graffiti to remain on any structure upon the lot or parcel.  Section 15.26.050 of the Municipal Code requires the owner or occupant of the lot or parcel to remove the graffiti within fifteen (15) days after notification by cleaning, painting or other method.

If the graffiti is not removed after 15 days, City staff will remove the graffiti from the property.  All costs associated with the removal of graffiti will be charged to the owner of the property per the Half Moon Bay Municipal Code Section 15.26.090.
