Fire Zones, AB 38, and Defensible Space: What Foothill Sellers Must Know

If your home is in a High or Very High Fire Hazard Severity Zone in California, the rules changed for selling it, and most owners do not know it until their listing hits a problem. This is not open-to-interpretation territory, so let us walk through what the law actually says.

What AB 38 is

Assembly Bill 38, chaptered in 2019, created a statewide program around fire safety, defensible space inspections, and home hardening disclosures. For real estate, the effect is straightforward: homes built before January 1, 2010 that sit in a high or very high fire hazard severity zone carry required disclosures when they sell.

• Sellers must give buyers a written disclosure noting the home is in a fire hazard zone and was built before modern wildfire building codes, along with details about what makes it vulnerable and how to harden it.
• Sellers must also document that the property meets locally adopted defensible space requirements, or disclose in writing that they could not obtain that documentation.
• It is a disclosure and documentation law, not a forced retrofit mandate. You do not have to fix everything, but you must tell the truth about it, in writing.
• Defensible space itself is required of owners in these zones under Public Resources Code 4291, independent of any sale.

Why insurance changed the conversation

Foothill buyers now get insurance quotes before they sign offers, not after, because carriers grade defensible space and home hardening. The state's Safer from Wildfires regulation ties premium discounts to specific hardening and defensible-space measures, which means the work a seller does can be money in the bank at sale time. A home with a clean defensible-space inspection and documented hardening sells faster and for more than the identical home without it.

What sellers should do now

• Find out your Fire Hazard Severity Zone before you list. We map it for every property we take.
• Get the defensible space inspection done early, while there is time to fix what it finds.
• Keep the paperwork: inspection records, clearance documentation, and retrofit receipts become closing documents.
• Prepare buyers for the insurance conversation with the actual evidence, not a hand-wave.

"The county will ask, the buyer's lender will ask, and the insurance carrier will ask. We get you the answers before anyone asks."

If your property is in a fire zone, do not wait until the listing photos are done to learn the rules. Call us first and we will walk your property against the checklist that matters. Take care, Doug.
