What California law requires when selling property in a fire hazard zone
Last reviewed: March 2026 · Effective: July 1, 2021 · Enacted by: AB 38 (2019)
What this law is
California Civil Code Section 1102.19 is the specific code section that requires sellers of residential property in a High or Very High Fire Hazard Severity Zone (FHSZ) to provide the buyer with documentation showing the property is in compliance with defensible space requirements before the close of escrow. It was enacted by Assembly Bill 38 (AB 38) in 2019 and took effect July 1, 2021.
The requirement is straightforward: if you are selling property in a High or Very High FHSZ, you must obtain a defensible space inspection showing your property meets the requirements of Public Resources Code (PRC) 4291 — or the applicable local vegetation management ordinance — and provide that documentation to the buyer before escrow closes.
If the documentation cannot be obtained before the close of escrow, the law provides an alternative: the seller and buyer may enter into a written agreement in which the buyer agrees to obtain documentation of compliance within one year of the close of escrow. This agreement does not waive the compliance obligation — it transfers the timeline. The property must still come into compliance.
Civil Code 1102.19 is distinct from but related to AB 38’s home hardening disclosure requirement. AB 38 requires disclosure of a home’s fire vulnerability features and completed retrofits for homes built before January 1, 2010. Civil Code 1102.19 requires proof of defensible space compliance for all property sales in fire hazard zones, regardless of when the home was built.
The fire science behind it
Civil Code 1102.19 exists because defensible space compliance is one of the most measurable factors in whether a structure survives a wildfire — and because non-compliant properties are a documented fire risk not just to their owners but to neighboring structures and firefighters.
Research by CAL FIRE and post-fire investigations consistently show that the condition of a property’s defensible space affects fire behavior in the immediate structure zone. A property with unclearance vegetation creates continuous fuel that allows fire to travel from the surrounding landscape directly to the structure. It also reduces the margin of safety for firefighters attempting to defend the property.
The point-of-sale compliance requirement addresses a specific problem: properties that change ownership without any defensible space review can transfer fire risk to new owners who may not be aware of what they are inheriting. A buyer who has never managed a rural or semi-rural property in a fire hazard zone may not understand what compliance requires or how quickly vegetation returns after clearing. The inspection requirement at point of sale creates a documented baseline.
Standard defensible space requirements apply a uniform rule based on distance and vegetation type. A fire-informed assessment goes further — evaluating the specific slope, fuel load, structure placement, and access conditions of a property to identify where risk is most concentrated and what actions would most reduce it. That kind of analysis is particularly valuable at the point of sale, when buyers are making decisions about the property they are about to own. Learn more at Cal Wildfire Defense.
Who this law applies to
Civil Code 1102.19 applies to any seller of residential real property located in a High or Very High FHSZ — in both the State Responsibility Area (SRA) and the Local Responsibility Area (LRA). It applies regardless of when the home was built.
The law covers residential properties including single-family homes, 1–4 unit properties, condominiums, manufactured homes, and common interest development units that require a Real Estate Transfer Disclosure Statement (TDS). It also applies to lots/planned developments — the requirement is not limited to single-family homes.
For sellers in San Diego County’s fire-country communities — Alpine, Descanso, Julian, Pine Valley, Fallbrook, Ramona, Warner Springs, Lakeside, Santee, and surrounding areas — Civil Code 1102.19 is an active requirement on virtually every residential sale. Many of these communities also have local vegetation management ordinances that layer additional requirements on top of state law.
Nothing in Civil Code 1102.19 limits the ability of CAL FIRE or a local agency to enforce defensible space requirements independently of a real estate transaction. The compliance obligation is permanent — the point-of-sale requirement is an additional trigger, not the only enforcement mechanism.
What it requires
Documentation of defensible space compliance
The seller must provide the buyer with documentation showing the property is in compliance with PRC 4291 — the 100-foot defensible space requirement — or the applicable local vegetation management ordinance, before the close of escrow.
This documentation is typically obtained through a formal defensible space inspection conducted by CAL FIRE, a local fire agency, or a qualified third-party inspector where local agencies have approved that option. The inspection must be current — most agencies require the inspection to have been completed within a specified period, typically six months, prior to the close of escrow.
The buyer agreement alternative
If documentation of compliance cannot be obtained before the close of escrow, the seller and buyer may enter into a written agreement showing the buyer agrees to obtain documentation of compliance within one year of the close of escrow. This is not a waiver of the compliance requirement — it is a transfer of the obligation to the buyer with a defined timeline.
Buyers considering this agreement should understand what they are taking on. Bringing a non-compliant property into compliance may require significant vegetation management work, particularly on larger parcels or properties that have not been maintained. A pre-purchase fire-informed assessment can identify what that work involves and what it will cost before the buyer commits to the agreement.
Local ordinances may be stricter
San Diego County and many of its fire-protection districts have local vegetation management ordinances that exceed state minimums. Where a local ordinance exists, compliance with that ordinance — not just PRC 4291 — is required for the documentation. Buyers and sellers should verify which standard applies to the specific property before scheduling an inspection.

Enforcement
Civil Code 1102.19 is enforced through the real estate transaction process. A seller who fails to provide documentation of compliance — or a written buyer agreement — before the close of escrow is in violation of the disclosure requirement. This can expose the seller to liability for non-disclosure in a real estate transaction.
Real estate agents representing sellers in High or Very High FHSZ have an independent professional obligation to ensure their clients understand and meet the disclosure requirements. The California Association of Realtors has updated its standard disclosure forms to reflect these requirements.
Separately, CAL FIRE’s enforcement of defensible space requirements under PRC 4291 operates independently of real estate transactions. A property that passes a point-of-sale inspection in spring may be out of compliance by summer if vegetation has grown back. The compliance obligation is ongoing — the point-of-sale inspection documents the condition of the property at one point in time.
Addressing the underlying risk
Civil Code 1102.19 creates a compliance requirement at the point of sale. But the fire risk it is designed to address is present year-round, not just when a property changes hands. A property that meets PRC 4291 standards at close of escrow protects its owners, its neighbors, and the firefighters who may be called to defend it — not just the buyer in that transaction.
For sellers — get ahead of the inspection
The most common problem sellers face under Civil Code 1102.19 is discovering non-compliance late in escrow, when there is insufficient time to complete the required vegetation management work before closing. Scheduling a defensible space inspection — or a pre-inspection fire-informed assessment — early in the listing process eliminates that risk. It also gives sellers accurate information about what work is needed, which allows them to price the property correctly and avoid surprises.
For buyers — understand what you’re inheriting
A defensible space inspection at close of escrow documents compliance with minimum standards at a point in time. It does not tell a buyer what the property will require for ongoing maintenance, how quickly vegetation returns on that specific parcel, or whether the property has features — slope, fuel type, structure placement, fencing — that create risk beyond what a standard inspection measures. A fire-informed pre-purchase assessment provides that analysis and gives buyers the full picture before they close.
For properties with the buyer agreement
If you are a buyer who has taken on the one-year compliance obligation, the clock starts at close of escrow. Start the process early — schedule an inspection within the first few months, so that if work is required you have time to complete it and obtain documentation before the deadline. Vegetation management on rural properties takes time, and dry season constraints may limit when work can be done.
A fire-informed assessment identifies exactly what needs to be done, in what priority order, to bring the property into compliance — and gives you documentation you can use when you schedule the formal inspection.
