The Short Version
San Francisco regulates fire pits and outdoor recreational fires under the locally adopted California Fire Code Section 307 and additional San Francisco Fire Department (SFFD) regulations. Recreational fires in approved portable fire pits are permitted with required clearances and attendance, but open burning on bare ground is prohibited within city limits. Wood-burning fire pits are subject to Bay Area Air Quality Management District (BAAQMD) no-burn day restrictions. Gas and propane fire pits are exempt from air quality burn restrictions and are the preferred option in San Francisco's dense neighborhoods.
Full Breakdown
San Francisco adopts the California Fire Code with local amendments, and Section 307 governs recreational fires, portable outdoor fireplaces, and open burning within the city. All uncontained open burning — including burning of yard debris, leaves, wood scraps, trash, or any material on bare ground or in an unapproved container — is strictly prohibited within city limits. Only contained recreational fires in approved fire pits, metal fire rings, chimineas, or portable outdoor fireplaces are permitted on private residential property.
For permitted recreational fires, the SF Fire Code requires a minimum clearance of 15 feet from any structure, including the primary residence, accessory buildings, fences, and neighboring structures. The fire pit or container must have a spark arrestor screen in place during use. The fuel area must not exceed 3 feet in diameter, and the fire height must not exceed 2 feet above the container rim. A responsible adult must attend the fire at all times, and a connected garden hose or other approved extinguishing equipment must be immediately available. The fire must be completely extinguished before being left unattended.
San Francisco is within the jurisdiction of the Bay Area Air Quality Management District (BAAQMD), and all wood-burning devices — including outdoor fire pits, fire rings, and chimineas — are subject to BAAQMD Winter Spare the Air alerts during which wood burning is prohibited. Gas and propane fire pits are exempt from these restrictions and may be used at any time. Given San Francisco's fog, wind, and compact lot sizes, the SFFD recommends gas or propane fire pits over wood-burning devices for residential use. The SFFD may impose additional outdoor fire restrictions during periods of elevated fire danger, particularly during dry offshore wind events.
What Happens If You Violate This?
Illegal open burning in San Francisco carries fines starting at $500 for a first offense under the Fire Code. Failure to maintain required clearances or attend an active fire results in citations starting at $250. Fires that cause property damage or endanger life may result in criminal charges. BAAQMD violations for wood burning during Spare the Air alerts carry fines starting at $100 for a first offense, escalating to $500 for subsequent violations. Report fire hazards to SFFD at 415-558-3200 or through SF 311.
