A seller of a house in a high or very high fire hazard severity zone on the Palos Verdes Peninsula owes the buyer two things that did not exist before 2021: a home hardening disclosure that lists the specific features of the house that make it vulnerable to embers, and documentation of a defensible space inspection done within six months before the sale, or, if there is none, the buyer’s written agreement to get one within a year of closing. The buyer gets a list of what to fix and, in a state where insurers now price hardening, a map to the discounts. This is what the law requires, which South Bay addresses it covers after the 2025 hazard maps, how the inspection works, what the disclosures look like, and why a careful seller does the inspection before listing rather than after.
Which South Bay addresses are in a fire hazard severity zone?
The ones on the hill. The State Fire Marshal classifies land as moderate, high or very high fire hazard on the basis of fuel, slope, fire weather and ember transport over a 30 to 50 year horizon, without credit for what an owner has done to mitigate, per the Office of the State Fire Marshal. The updated maps for the local responsibility areas of Los Angeles County were released in phases in February and March 2025, and under Government Code section 51179 each city had 120 days to adopt them by ordinance, with the power to add to the state’s zones but not to subtract. On the Peninsula, the canyon and slope neighborhoods of Rancho Palos Verdes, including the Portuguese Bend side and the areas around the nature preserve, parts of Palos Verdes Estates along its canyons and bluffs, and Rolling Hills, which has treated itself as very high hazard for years, carry the designations that trigger the rules below. The flat beach cities and most of Torrance do not. The line is drawn parcel by parcel, and the state’s map viewer and each city’s adopted map are where a seller confirms it; the Natural Hazard Disclosure report that every California seller orders will state the answer, because the very high zone is one of the six statutory items it covers.
What is the home hardening disclosure?
A statement, required by Civil Code section 1102.6f, from a seller of a house in a high or very high fire hazard severity zone that was built before January 1, 2010. The seller must state that the property is in a hazard zone and that the state’s building codes for wildfire areas may apply, point the buyer to the state’s Ready for Wildfire resources, and list which of the specific vulnerability features the house has: roof vents that are not ember resistant, a wood shingle roof, combustible landscaping within five feet of the structure, single pane windows, roof damage, uncovered rain gutters, and the rest of the statutory list. Since July 1, 2025, the seller must also state which of the state’s low-cost retrofits have been completed, from the list the State Fire Marshal published under Government Code section 51189. A seller who has had a defensible space inspection under section 51182 must give the buyer a copy of the report. The California Association of REALTORS® packages all of this on its fire hardening and defensible space disclosure form, and the form is now part of every Peninsula listing package we prepare.
What is the defensible space documentation requirement?
The second half of the same 2019 law, AB 38, codified at Civil Code section 1102.19 and operative since July 1, 2021. A seller of property in a high or very high zone must provide the buyer with documentation that the property complies with the defensible space requirements of Public Resources Code section 4291 or the local vegetation management ordinance, obtained within the six months before the sale. If the seller does not have it, the buyer and seller sign a written agreement in which the buyer agrees to obtain the documentation, within a year of closing where no local ordinance sets a different period. The statute does not stop the fire agency from enforcing defensible space on its own schedule; it puts the compliance question into the transaction so that nobody buys a hillside house without knowing where it stands.
What does defensible space actually require?
One hundred feet, in zones, per Government Code section 51182 for the local responsibility areas that cover the Peninsula cities and Public Resources Code section 4291 for state responsibility areas. The owner of an occupied dwelling in a very high zone must maintain defensible space of 100 feet from each side of the structure, not extending beyond the property line; more intensive fuel reduction in the zone from 5 to 30 feet; an ember-resistant zone within 5 feet of the structure, cleared of anything likely to ignite from embers; ten feet of clearance between tree branches and any chimney or stovepipe; trees and shrubs free of dead wood; and a roof kept clear of leaves and needles. The five foot ember-resistant zone, which the state calls Zone 0, is the item that has been changing. The Governor’s February 2025 executive order directed the Board of Forestry and Fire Protection to complete its Zone 0 regulations by the end of 2025; as of the Board’s August 2026 meeting materials the rule package was still in final review at the Office of Administrative Law, per the Board’s Zone 0 page, and an owner should check that page for the current status, because once it takes effect it will govern what can sit against the house, from mulch to a wood fence to the hedge under the eaves.
On the Peninsula the inspecting agency is the Los Angeles County Fire Department, which runs the Fire Hazard Reduction Program with the county Agricultural Commissioner: annual defensible space notices go out each spring, parcels are inspected, uncleared hazardous vegetation is declared a public nuisance, the base requirement is a 100 foot radius and up to 200 feet where the structure’s siting requires it, and an owner who does not clear is cleared by the county and billed. The department’s inspection record is the documentation section 1102.19 contemplates, and a seller can request an inspection rather than wait for the annual cycle. Rolling Hills, Palos Verdes Estates and Rancho Palos Verdes each add their own brush clearance and fuel modification rules on top of the county’s program, and the city’s ordinance is the one to read for a specific lot.
How does the C.A.R. partner program work?
The California Association of REALTORS® runs a wildfire disclosure partner program with a vendor, FortressFire, that produces two products for a listing. The first is a Wildfire Disclosure Report, an assessment of the property’s vulnerability from imagery, aligned to the fields of the AB 38 disclosure and ordered through the natural hazard disclosure companies most agents already use. The second is an on-site inspection: a ground level assessment of the structure, the vegetation and the defensible space, with a report, an inventory of the vulnerabilities found, a quote for the mitigation work, and a checklist keyed to the standards that insurers use in underwriting. The vendor credits the cost of the report toward the inspection. For a Peninsula seller the value is in the order of events: the inspection before the listing tells the seller what an underwriter and a buyer’s inspector will find, and the mitigation done before the photographs is worth more than the same work done as a repair credit in escrow.
Why does hardening now change the insurance?
Because the Department of Insurance requires it to. Under the state’s Safer from Wildfires framework, adopted in 2022, insurers must offer discounts for a defined set of mitigation measures: a Class A fire-rated roof, a five foot ember-resistant zone, ember and fire resistant vents, six inches of noncombustible material at the base of exterior walls, enclosed eaves, multi-pane windows, clearance of combustibles from under decks, and compliance with defensible space rules, along with community-level measures such as Firewise recognition. The FAIR Plan offers up to 20 percent off the wildfire portion of its premium for hardened homes, and the Insurance Institute for Business and Home Safety’s Wildfire Prepared Home designation, in a base and a plus tier, gives an owner a third-party certificate that several carriers recognize. We wrote about the insurance market itself, the FAIR Plan and the new rating rules in insuring a hillside or coastal home in the South Bay. The link between that piece and this one is the seller’s disclosure: the features the law makes a seller list are, item for item, the features the insurer discounts, and a seller who has done the work has an easier sale and a buyer who has an easier policy.
What should a Peninsula seller do, and in what order?
| Step | Timing |
|---|---|
| Confirm the parcel’s fire hazard severity zone on the state viewer and the city’s adopted map | Before anything else; the rules below apply only if the parcel is in a high or very high zone |
| Order a defensible space inspection from the county fire department or the C.A.R. partner vendor | Three to six months before listing, so the documentation is within the six month window at sale and there is time to clear |
| Do the low-cost retrofits: vents, gutter covers, the five foot zone, the wood under the deck | Before photography; each one is a line on the disclosure that reads “completed” |
| Complete the home hardening and defensible space disclosure with the inspection report attached | With the rest of the disclosure package, delivered at or before acceptance |
| Provide the current insurance declarations page and any carrier inspection letters | With the disclosures; buyers’ brokers ask for them on day one |
A buyer’s list is shorter: read the two disclosures, walk the property with the inspection report in hand, get the insurance quote before the contingency ends, and if the seller has no defensible space documentation, understand that the written agreement to obtain it within a year is a real obligation with the county’s enforcement behind it. None of this makes a Peninsula canyon house a bad purchase. It makes it a purchase with a known list, which is the only kind we recommend.
If you are selling a house in a hazard zone on the Peninsula, in Rancho Palos Verdes, Palos Verdes Estates or Rolling Hills, we will tell you what the inspection will find before you order it. Send Neil the address, and see the Sellers page for how the disclosure package fits into the listing.
