8 rules for unincorporated Sierra County, California.
Verified from official government sources
Sierra County has not adopted a standalone fire-pit ordinance, but recreational fires are governed by the California Fire Code (adopted in Sierra County Code 12.04.080) and CAL FIRE rules. During fire season, open flames in the State Responsibility Area generally require a CAL FIRE campfire permit, and burning is restricted on no-burn days.
Nearly all of unincorporated Sierra County is a State Responsibility Area (SRA) where ALL fireworks — including state-approved 'Safe and Sane' fireworks — are illegal to use, possess, or sell. Vast federal forest lands (Tahoe and Plumas National Forests) likewise prohibit all fireworks. Violations are misdemeanors, and offenders are billed for fire-suppression costs.
Because nearly all of unincorporated Sierra County is a State Responsibility Area, property owners must maintain 100 feet of defensible space around buildings under California Public Resources Code 4291. This includes an ember-resistant 0-5 foot zone, intense fuel reduction from 5-30 feet, and reduced fuel from 30-100 feet. CAL FIRE inspects and enforces.
Residential outdoor burning in Sierra County is regulated by the Northern Sierra Air Quality Management District. Only dry vegetation grown on the property may be burned, only on declared permissive burn days, and a CAL FIRE burn permit is required during fire season. Burn barrels are illegal statewide, and burns over one acre need an additional air-district permit.
Nearly all of unincorporated Sierra County is a State Responsibility Area in forested Sierra Nevada terrain, with extensive High and Very High Fire Hazard Severity Zones mapped by CAL FIRE under PRC 4201-4204. These designations trigger 100-foot defensible space (PRC 4291) and influence building standards. CAL FIRE and federal agencies (Tahoe/Plumas NF) cover the county.
Sierra County adopts the California Building Standards Code, including the California Residential Code (Code Section 12.04.080), which carries statewide smoke- and carbon-monoxide-alarm rules. Under California Health and Safety Code 13113.7, smoke alarms are required in every bedroom, outside each sleeping area, and on every floor. CO alarms are required where fuel-burning appliances or attached garages exist.
Backyard open fires in Sierra County combine two rule sets: the Northern Sierra Air Quality Management District allows burning only dry on-site vegetation on permissive burn days, and CAL FIRE requires a burn permit during fire season because the county is a State Responsibility Area. Recreational warming/cooking fires follow California Fire Code attendance and clearance rules.
Sierra County Code 12.04.080 adopts NFPA 58 (the Liquefied Petroleum Gas Code) and the California Fire/Mechanical Codes for propane tank installation. Above-ground residential tanks of 125-500 gallons must generally be at least 10 feet from buildings and property lines, kept clear of vegetation, and installed by permit. Larger tanks require greater setbacks.
