Graffiti are an ongoing problem in Oakland. It seems that no sooner are they painted over than the tags are back. If we want to keep our neighborhoods clean and free of graffiti, we the citizens have to act. Graffiti are a "quality of life" issue, a minor crime with a disproportionately large effect on the neighborhood.
If graffiti are on your property, you are responsible for cleaning them up.
If graffiti are anywhere else, call the Public Works Call Center at 510-615-5566.
For background information, here is the text of the City Administrator's report to the City Council on Graffiti Abatement, dated June 24, 2008:
Oakland Public Works can't clean up graffiti on CalTrans property - freeway underpasses and signs, including on-ramp and off-ramp signs. Oakland Police Department also can't enforce laws against homeless camps on CalTrans property.
You can report graffiti, and any other type of problem on CalTrans property, directly on their website page:
The site also accepts reports of most types of problems, from damaged fencing to litter and illegal dumping, including homeless encampments.
