One of the Favorite thing you find in San Francisco is the street art. San Francisco Bay Area Street Art are any visual images created in public places such as on walls or street walk ways. Street art is often developed in order to create artworks that are outside of the scope of normalized art standards. Street Art has been a major part of the Bay Area's culture since the early 1980s. As the years went on street art became more and more prevalent in the Bay Area. While in some areas of San Francisco this art is done with the permission of the wall owners the majority is done illegally.
