How San Leandro Handles Fire Regulations: A Practical Guide

San Leandro maintains 151 local ordinances across all categories, and 8 of those deal specifically with fire regulations. Here is a breakdown of what the city actually requires, what is prohibited, and where San Leandro falls on the strict-to-permissive spectrum compared to other cities.

Backyard Fires

Backyard recreational fires in San Leandro are allowed in approved pits under 3 ft diameter with 15 ft setback, banned on Spare the Air days.

Key details: Allowed Fuel: Clean dry firewood. Attendance: Required at all times. Setback: 15 ft structures. Spare Air: No wood fires. Extinguisher: Must be on hand.

Nuisance smoke can trigger abatement plus a 100 dollar citation. BAAQMD violations start at 100 dollars for first wood-smoke infractions.

Brush Clearance

SLMC §3-2-205 caps grass and weeds at 4 inches in height citywide; properties in the newly mapped High Fire Hazard Severity Zone (adopted June 2025 from CAL FIRE 2025 maps) must also meet Public Resources Code §4291 / Government Code §51182 defensible space - 100 feet of clearance around structures.

Key details: Citywide weed-height limit: 4 inches (SLMC §3-2-205). Nuisance code: SLMC §3-1-200 (Community Preservation Ordinance). Defensible space (High FHSZ): 100 ft per PRC §4291 / Gov Code §51182. 2025 FHSZ map status: Moderate + High added; Very High eliminated (CAL FIRE Feb 2025). First citation fine: $100 (Chapter 1-12 administrative).

SLMC §3-2-205 / §3-1-200 violations are enforced by Code Enforcement under SLMC Title 1, Chapter 1-12 (administrative citations) - typically a courtesy notice, then a $100 first citation, $200 second, $500 third and subsequent, plus city cost-recovery if the City abates the weeds. Defensible space violations under PRC §4291 / Gov Code §51182 are infractions punishable by fines from $100 (first violation) to $500 (subsequent), and the local fire agency may abate and lien the property.

Outdoor Burning

Open burning of yard waste, leaves, brush, or trash is effectively banned in San Leandro. The Bay Area Air Quality Management District Regulation 5 (Open Burning) prohibits residential open burning year-round in urbanized Alameda County, and California Fire Code §307 (adopted by SLMC §7-5-810) requires permits for any open fire.

Key details: Yard-waste burning: Prohibited - use green-cart collection. BAAQMD rule: Regulation 5 (Open Burning, 2025 amendment). Permissive burn seasons: Mar 1 - Apr 15 and Sept 1 - Oct 15 (limited categories, not yard waste). Fire code permit: Required for any open fire (CFC §307.1). Spare the Air days: All outdoor wood burning banned.

BAAQMD open-burning violations are misdemeanors under California Health & Safety Code §42400 - up to $1,000 per day for negligent violations, up to $10,000 per day for knowing violations, and up to $25,000 per day with potential 1-year jail for violations that emit toxic air contaminants. Permit-less open burning under CFC §307.1 / SLMC §7-5-810 is a misdemeanor (CFC §109.3) and the Fire Code Official may order immediate extinguishment. Report illegal burning to BAAQMD at 1-800-334-ODOR (6367).

Compared to other cities, San Leandro takes a harder line on outdoor burning. The enforcement and penalty structure reflects that.

Wildfire Zones

CAL FIRE's Feb 24, 2025 LRA Fire Hazard Severity Zone maps (adopted by San Leandro City Council mid-June 2025) designate hillside neighborhoods east of I-580 as Moderate and High FHSZ. The prior Very High zone was eliminated. Properties in mapped zones must follow California Building Code Chapter 7A (Wildland-Urban Interface) and PRC §4291 defensible space.

Key details: Map vintage: CAL FIRE 2025 LRA maps (released Feb 24, 2025). Zones in San Leandro: Moderate + High (Very High eliminated). Defensible space (High): 100 ft per PRC §4291. WUI building standards: California Building Code Chapter 7A in High FHSZ. Real estate disclosure: Required under Natural Hazard Disclosure Statement.

Defensible space violations under PRC §4291: $100 first violation, up to $500 subsequent; failure to abate after notice authorizes the local fire agency to abate and lien the property. WUI Chapter 7A non-compliance is a stop-work and certificate-of-occupancy issue enforced by San Leandro Building & Safety. Failure to provide a Natural Hazard Disclosure can void real estate transactions or expose sellers to civil liability under Civil Code §1102.13.

Fire Pit Rules

San Leandro adopts the 2022 California Fire Code under SLMC §7-5-810, which incorporates California Fire Code §307.4 governing recreational fires and portable outdoor fireplaces. Wood burning in outdoor fire pits is also illegal anywhere in the Bay Area on any day a Spare the Air Alert is in effect (BAAQMD Regulation 6, Rule 3).

Key details: Fire-code adoption: SLMC §7-5-810 adopts 2022 California Fire Code. Recreational fire size limit: 3 ft diameter, 2 ft tall (CFC §307.4.2).

Permit required for recreational fire: No (residential R-3) unless prohibited by Fire Marshal.

Recreational-fire violations of the California Fire Code are enforced by the Alameda County Fire Department (which contracts to provide fire services to San Leandro) and are misdemeanors under CFC §109.3 / Health & Safety Code §13871, punishable by fines and abatement. BAAQMD wood-burning violations carry an administrative fine that starts at $100 for a first offense and escalates to $500+ per day for repeat offenses; BAAQMD takes complaints at 1-877-4NO-BURN.
