8 rules for unincorporated Trinity County, California.
Verified from official government sources
Small recreational campfires are treated separately from debris burning, but in Trinity County's State Responsibility Area a CAL FIRE campfire permit is required for open fires outside developed campgrounds during fire season. Defensible space and a 10-foot cleared area apply.
Trinity County is entirely wildland: 100% of the county is State Responsibility Area or federal land. Fireworks are always prohibited on national forest land, and 'dangerous' (aerial/exploding) fireworks are illegal statewide. There is effectively nowhere to legally discharge consumer fireworks in this extreme-fire-risk county.
Because all of Trinity County is State Responsibility Area, state law (PRC 4291) requires 100 feet of defensible space around structures. The county's Fire Safe Ordinance (Chapter 8.30) adds fuel-clearance, access, signage, and water-supply standards for new development.
Open burning of yard debris requires both a North Coast Unified AQMD burn permit and (in fire season) a CAL FIRE permit. Burning is allowed only on declared permissive burn days, during set hours, on a property with a residence. Burning garbage is illegal.
All of Trinity County is within State Responsibility Areas or federal land, and many communities are in the wildland-urban interface mapped as High or Very High Fire Hazard Severity Zones. PRC 4291 defensible space and the county Fire Safe Ordinance apply, and wildfire risk is rising with climate change.
Trinity County follows California state law. Smoke alarms are required in every dwelling intended for human occupancy (HSC 13113.7/13113.8), and carbon monoxide alarms are required under the Carbon Monoxide Poisoning Prevention Act of 2010 in homes with fuel-burning appliances, fireplaces, or an attached garage.
Open backyard burning of debris needs an NCUAQMD permit (and a CAL FIRE permit on SRA land) and is allowed only on permissive burn days. Small recreational fires are exempt from the air-district permit but still need a CAL FIRE campfire permit on State Responsibility Area land.
Trinity County does not publish a separate propane ordinance; storage follows the California Fire Code and NFPA 58. Above-ground residential tanks of 125-500 gallons must generally sit at least 10 feet from any building, property line, and ignition source. Defensible space rules also apply around tanks.
