If you are selling a home in a California fire hazard zone, you will probably need paperwork showing your defensible space passed a fire department inspection. That rule comes from AB 38, and it catches many sellers off guard because the inspection is separate from your home inspection and the clock is shorter than most people expect. This guide covers who needs one, how it works in Los Angeles County, Malibu and Truckee, and how to get ready.
What AB 38 actually requires
Since July 1, 2021, California AB 38 has required owners selling a home in a High or Very High Fire Hazard Severity Zone to give buyers documentation proving compliance with defensible space requirements. The legal hook is Civil Code Section 1102.19. The underlying standard is Public Resources Code 4291, which, as the Town of Truckee explains, requires 100 feet of defensible space to the property line around structures.
Two details matter for your timeline:
- The report has a shelf life. Los Angeles County Fire notes that a compliant inspection completed in the previous six months meets the AB 38 requirement. Truckee Fire uses the same window, tied to the transaction date.
- There is a fallback. If compliance documentation is not available before closing, the buyer and seller may agree in writing that the buyer will obtain it within one year of closing.
The inspection exists for the sale. LA County Fire says AB 38 inspections are for real estate sales disclosure and documentation only. A passing report is not an insurance document, and your carrier sets its own requirements and final pricing.
Is your address in a zone that triggers it?
This is where many Los Angeles area owners are surprised. CAL FIRE issued new Local Responsibility Area maps for LA County on March 24, 2025. These maps classify land as moderate, high or very high using current data on fuels, fire history, weather and terrain. LAist reported that very high hazard now extends north of Ventura Boulevard in parts of the San Fernando Valley, and that very high hazard also expanded in Altadena and Pasadena.
The LA County Board of Supervisors adopted the updated zones on July 22, 2025. The ordinance set an operative date of 30 days after adoption. If you bought your home a decade ago and it was outside a zone then, it may be inside one now.
To check your address:
- Use the CAL FIRE Fire Hazard Severity Zone viewer. The state's viewer shows State Responsibility Area zones effective April 1, 2024, and Local Responsibility Area zones as recommended March 24, 2025.
- Confirm with your local agency. The viewer itself says that to verify your zone in a Local Responsibility Area, you should contact your local agency.
- Remember what a zone means. These maps describe hazard, not your home's individual risk. One city fire page puts it this way: the maps indicate hazard potential and do not account for mitigation like defensible space or fire-resistant construction.
For Los Angeles County properties, the county's AB 38 page says that inspections are only required if your home is in a Local Responsibility Area Very High zone, or a State Responsibility Area High or Very High zone. Your agent or escrow officer can confirm which applies to you, and the natural hazard disclosure report will flag the zone as well.
How the inspection works in LA County, Malibu and Truckee
The process is similar everywhere: you request an inspection, the fire agency walks the property, and you either pass or get a list of items to fix. Who does the inspection depends on your location.
Malibu. All of Malibu is designated Very High, so every sale inside city limits is subject to AB 38. The city notes that its Fire Safety Liaisons cannot conduct AB 38 inspections, and owners or agents should contact the Los Angeles County Fire Department Fire Prevention Division. If you own in Malibu, start there.
Unincorporated LA County and contract cities. LA County Fire handles requests through an online form, and the county says typing your address into its request tool shows whether your home is in a High or Very High zone. Other cities run their own programs. Glendale, for example, charges a $43 fee for the inspection. Fees and forms vary by agency, so check yours.
Truckee. Truckee Fire Protection District requires that sellers provide a Truckee Fire inspection report confirming compliance, from an inspection within the six months before the transaction date. Some details are specific to Truckee:
- Truckee Fire does not issue a certificate of compliance, and the front page of the inspection report is commonly used instead.
- An HOA inspection is not a substitute for Truckee Fire's inspection, unless specifically authorized.
- The inspector may be on site for about 10 to 30 minutes and does not need access inside your buildings.
- Winter matters. Truckee Fire suspends defensible space inspections in the winter because of weather and staffing limits. The district's fall-winter update says that if the calendar closes, real estate transactions are not held up, because buyers can take responsibility for compliance within one year.

The July 2025 hardening disclosure
AB 38 also changed what sellers must say about the house itself. Since July 1, 2025, sellers must provide information about fire-resistant retrofits using the State Fire Marshal's Low-Cost Retrofit List, and disclose whether any of those retrofits were completed during their ownership.
Sellers must also disclose known vulnerabilities. Glendale's summary of the law lists:
- Gaps in eaves, siding or roofing where embers could enter
- Single-pane or non-tempered glass windows
- Roofing not rated Class A
- Vents without noncombustible or ember-resistant screens
- Combustible materials or landscaping within 5 feet of the home
- Gutters without noncombustible covers
- Missing metal flashing where decks meet walls
The exact build-year cutoff for the checklist is described differently by different sources, so ask your agent or escrow officer whether your home is covered. One law firm summary adds that the rule emphasizes disclosure and transparency, not mandatory upgrades. Still, every item on that list is something a buyer's agent and insurer can read.
What this means for your home
Whether you are selling this spring or just want to stay ahead of the rules, this sequence works well:
- Confirm your zone early. Check the state viewer, then verify with your local fire agency. Do this before you list, not after you are in contract.
- Request the inspection after the work, not before. Truckee Fire advises that the fastest route is often hiring a knowledgeable professional to complete the defensible space work, then requesting the inspection. The same logic applies in LA County.
- Mind the six-month window. Time the inspection so the report is still valid at close of escrow. A long escrow or a delayed listing can push it out of range.
- Walk the five-foot zone yourself. Mulch, wood planters, doormats and stored items against the walls are the easy flags. Our Zone 0 guide shows what to clear.
- Read the vulnerability list as a to-do list. Eave gaps, open vents and uncovered gutters are common. Ember-resistant vents and gutter covers are among the more straightforward fixes. Pairing them with brush work covered in our LA brush clearance guide addresses both the inspection and the disclosure.
- Keep records. Dated photos, invoices and inspection reports help the sale, and they may help when you talk to your insurance carrier. Your carrier sets final pricing, and no upgrade guarantees a particular result.

Frequently asked questions
Do I need an AB 38 inspection if my home is in a Moderate zone?
No. The requirement applies to properties in High or Very High Fire Hazard Severity Zones. Every California seller still provides a natural hazard disclosure, which will show your zone. Confirm your status with your local fire agency or agent.
What if I can't get an inspection before escrow closes?
The law allows a written agreement in which the buyer takes on responsibility to obtain compliance documentation within one year of closing. Truckee Fire points sellers to the California Association of Realtors advisory form for this. Ask your agent whether it fits your sale, since a lender or buyer may prefer the report.
Does passing the AB 38 inspection help with my homeowners insurance?
Not automatically. LA County Fire describes these inspections as being for real estate documentation only. Insurers set their own underwriting rules, and your carrier sets final pricing. Documented defensible space and home hardening can still be useful records to share with your agent or carrier.
