The 2025 San Francisco Fire Code, effective January 1, 2026, adopts the 2025 California Fire Code with local amendments. Under the Fire Code's vegetation section (304.1.2), the owner or occupant must cut down and remove weeds, grass, vines and other growth that could catch fire and endanger property. Vegetation clearance in wildland-urban interface areas follows Chapter 49. Violations can be charged as infractions, with fines up to $130 for a first offense, $700 for a second within a year and $1,300 for each further one. They can also be charged as misdemeanors, with a $500 to $1,000 fine, up to six months in jail, or both. In a civil action, the city can seek up to $1,000 a day.

Its vegetation section requires owners or occupants to cut down and remove weeds, grass and vines that could catch fire and endanger property. The San Francisco Fire Department's Bureau of Fire Prevention enforces it. The State Fire Marshal's February 2025 map zones only about 500 acres of the city.
