How California's Dual Burn Authorization System Works
California's residential burning system involves two completely separate agencies with separate rules:
Authorization 1: CAL FIRE Residential Burn Permit
CAL FIRE (California Department of Forestry and Fire Protection) issues annual Residential Burn Permits for burning vegetative debris — leaves, brush, yard clippings — on single or two-family residential properties. This permit is valid from the date of issue through April 30 of the current year. It authorizes burn piles no larger than 4 feet × 4 feet.
CAL FIRE permits apply only in State Responsibility Areas (SRA) — unincorporated, rural, and wildland areas where CAL FIRE (rather than local fire departments) has primary fire suppression responsibility. If you're in a city or Local Responsibility Area (LRA), your local fire department handles permits, not CAL FIRE.
Authorization 2: Air District Permissive Burn Day
California's 35 Air Quality Management Districts and Air Pollution Control Districts independently determine daily Burn Day Status based on meteorological conditions and air quality forecasts. Even with a valid CAL FIRE permit, you cannot legally burn on a "No Burn Day." Burn day status changes daily and is typically announced the day before or morning of.
Think of the CAL FIRE permit as your driver's license — it authorizes you to drive. The burn day designation is the traffic light — it tells you whether you can go right now.
Getting Your CAL FIRE Residential Burn Permit
- Go to fire.ca.gov/burnpermit — CAL FIRE's online permit portal. This is the fastest method and available 24/7.
- Enter your address — The system confirms you are in a State Responsibility Area. If not, it will direct you to your local fire authority.
- Watch the safety video — CAL FIRE requires permit applicants to watch a short (3–5 minute) fire safety video before issuing the permit. This is mandatory, not optional.
- Agree to safety conditions — Confirm you will follow the burn rules: pile size limits, burn windows, having water supply ready, and extinguishing completely.
- Receive your permit — The permit is emailed to you immediately. Print or save it to your phone. It is valid through April 30 of the current year.
How to Check if Today Is a Burn Day in California
This is where most California homeowners get tripped up. Unlike a static annual permit, burn day authorization changes every single day. Here is how to check for your area:
Major Air District Burn Day Resources
| Air District | Region Covered | How to Check Burn Status |
|---|---|---|
| SCAQMD | LA, Orange, Riverside, San Bernardino counties | aqmd.gov — daily burn day status page |
| BAAQMD | San Francisco Bay Area (9 counties) | baaqmd.gov — Spare the Air alerts |
| SJVAPCD | San Joaquin Valley (8 counties) | valleyair.org — burn day determination |
| CARB Regions | All other districts | arb.ca.gov — links to all district contacts |
| Local APCD | Varies by county | Call your county APCD directly |
Most air districts publish burn day status by 4 PM the prior day or by 7 AM on the day of burning. Some offer email or text alert subscriptions. If you can't find current status for your district, call them directly — it's a quick call.
Burn Day Terminology
- Permissive Burn Day: Burning is authorized today (with valid permit)
- No Burn Day: Burning is prohibited regardless of permit status
- Spare the Air Day: Bay Area terminology — burning prohibited due to air quality
- Wood Burning Curtailment: Some districts restrict wood-burning appliances separately from open burning
State Responsibility Area vs. Local Responsibility Area
Your location determines which agency issues your burn permit:
- State Responsibility Area (SRA): Unincorporated, rural, and wildland areas — CAL FIRE issues your permit at fire.ca.gov/burnpermit
- Local Responsibility Area (LRA): Cities and incorporated areas — your local fire department or county fire authority handles permits. Requirements vary significantly by city.
- Federal Responsibility Area (FRA): National forests and federal land — contact the relevant National Forest or BLM office. Different rules apply.
You can determine your area type by entering your address in CAL FIRE's permit portal — it will automatically identify your responsibility area and redirect you if needed.
What You Can Burn in California (Residential)
Allowed Under CAL FIRE Residential Permit
- Leaves, grass clippings, and yard trimmings from your residential property
- Small brush, twigs, and natural yard debris
- Burn piles no larger than 4 feet × 4 feet at the base
- Natural wood (untreated, unpainted, no composite materials)
Prohibited Statewide (No Permit Covers This)
- Garbage, household waste, or trash
- Construction or demolition debris of any kind
- Treated, painted, or composite wood products
- Agricultural burning (separate permit category, not covered by Residential permit)
- Tires, rubber, or synthetic materials
- Hazardous materials of any kind
Wildfire Zones and Extra Restrictions
California has designated High Fire Hazard Severity Zones (HFHSZ). If your property is in a Very High or Extreme HFHSZ — common in foothills, mountain communities, and the Wildland-Urban Interface — additional restrictions may apply beyond the standard Residential Burn Permit. CAL FIRE may impose supplemental conditions or restrict burn pile sizes further.
During active wildfire weather events — Red Flag Warnings issued by the National Weather Service — local fire authorities often implement total burn prohibitions that override all existing permits. If a Red Flag Warning is in effect for your area, do not burn regardless of permit status.
San Joaquin Valley: Very Limited Burn Days
Homeowners in the San Joaquin Valley (Fresno, Bakersfield, Modesto, Stockton, and surrounding communities) face some of the most restrictive burn day schedules in the state. The Valley has persistent air quality challenges due to geography — the mountains trap pollution and smoke. In practice, the San Joaquin Valley APCD issues very few Permissive Burn Days, particularly in fall and winter when temperature inversions are common.
If you live in the Valley, check valleyair.org before every planned burn. Many Valley residents find that composting, chipping, or using green waste collection is far more reliable than waiting for Permissive Burn Days.
California Penalties for Illegal Burning
- Burning without a permit: misdemeanor under California Health & Safety Code §41800
- Burning on a No Burn Day: violations up to $1,000 per day under air district rules
- Burning prohibited materials: penalties up to $25,000 per day
- If fire escapes: full suppression costs, civil liability for property damage
Frequently Asked Questions
If you live in a State Responsibility Area (most rural and unincorporated California), yes — a free CAL FIRE Residential Burn Permit is required for any outdoor burning of vegetative debris. In cities (Local Responsibility Areas), contact your local fire department. In all cases, you also need your Air District to declare a Permissive Burn Day before you can legally burn.
Visit your local Air Quality Management District's website or call their hotline. Each of California's 35 air districts publishes daily burn day status. Common resources: SCAQMD (aqmd.gov) for Southern California, BAAQMD (baaqmd.gov) for the Bay Area, and SJVAPCD (valleyair.org) for the San Joaquin Valley. Status is typically posted by 4 PM the day before or early morning on the burn day.
CAL FIRE Residential Burn Permits expire on April 30 each year. You must reapply annually at fire.ca.gov/burnpermit. The permit is free and the online process takes about 10 minutes including the required safety video.
Generally, no. While a Red Flag Warning itself doesn't automatically prohibit burning, most local fire authorities implement total burn bans during Red Flag conditions. More importantly, the air district will almost certainly not issue a Permissive Burn Day during Red Flag conditions due to extreme fire danger. If a Red Flag Warning is in effect for your area, treat it as a prohibition on burning.
