Wildfire Hardening and Defensible Space Disclosure (AB 38)

The seller makes both disclosures and signs. The buyer signs to acknowledge receipt, and — where the parties agree the buyer will obtain defensible space documentation after closing — the buyer's written agreement to that arrangement is the operative piece. Agents deliver the disclosures and should confirm the zone designation from the natural hazard report rather than from memory or a neighbor's assumption.

Note the trigger: the zone designation, plus (for hardening) a pre-2010 build date. The obligation follows the map, so the mapped zone finding in the NHD report is what tells you whether these forms apply at all.

With the seller's disclosure package, as soon as practicable before transfer of title. Ordering the natural hazard report at listing is what makes this workable: you cannot know whether AB 38 applies until you know the fire hazard severity zone.

The seller's defensible space documentation must have been obtained within the six months before entering into the transaction, and the inspection itself takes real calendar time in fire season — backlogs are common, so start early. If the parties instead agree the buyer will obtain documentation, put that agreement in writing in the contract: the local ordinance deadline controls where one exists, and otherwise the outside date is one year from the close of escrow.

Local vegetation management ordinances can be stricter than the state minimum, so read the ordinance for the jurisdiction the property sits in.

The immediate consequence is the same family as other statutory disclosure failures: an open buyer response right before closing, and a nondisclosure claim after. But wildfire disclosure has an additional practical edge — insurance. A buyer who closes on a home in a Very High Fire Hazard Severity Zone without the hardening disclosure, then cannot obtain or afford coverage, has both a concrete financial injury and a clear statutory hook.

Missing defensible space documentation also leaves the buyer holding an unquantified compliance obligation. Vegetation clearance around a hillside property can be a meaningful expense, and a buyer who learns of it after closing tends to look for someone to hand it to.

Checking the zone from the wrong map. Fire hazard severity zone maps have been redrawn; a designation from an old report may not match current mapping. Pull a current report.

Confusing the two obligations. Hardening disclosure and defensible space documentation are separate requirements with separate triggers. Satisfying one does not satisfy the other.

Assuming High zones are excluded. They are not. Both obligations reach High and Very High Fire Hazard Severity Zones; the pre-2010 build date is a trigger for the hardening disclosure only, not for defensible space.

Handling the one-year buyer agreement informally. If the buyer is taking on the compliance documentation, that belongs in the written agreement.

Skipping local ordinances. Many jurisdictions layer their own vegetation management rules on top of PRC 4291.
