What Is a Natural Hazard Disclosure Report in California?
Short answer: it is a one-page statutory form telling you whether the property sits inside six specific mapped hazard zones. It is not an inspection, not a risk score, and not an insurance opinion. The form changed on January 1, 2025, and the fire question on it now has four checkboxes instead of two. Most buyers sign it in a stack of paperwork without reading which box was ticked.
What does the Natural Hazard Disclosure actually cover?
Six zones, no more. The statutory form appears in Civil Code section 1103.2, under the heading "THIS REAL PROPERTY LIES WITHIN THE FOLLOWING HAZARDOUS AREA(S)":
- A special flood hazard area, any Zone A or V, designated by FEMA
- An area of potential flooding on a dam failure inundation map, under Government Code 8589.5
- A high or very high fire hazard severity zone, under Government Code 51178 or Public Resources Code 4201 and following
- A wildland area that may contain substantial forest fire risks, under Public Resources Code 4125
- An earthquake fault zone, under Public Resources Code 2622
- A seismic hazard zone, under Public Resources Code 2696
Anything outside that list is not on this form. Landslide history that never got mapped, a creek that floods but sits outside a FEMA polygon, soil problems, none of it appears. The form says so itself, in capitals: the maps "ESTIMATE WHERE NATURAL HAZARDS EXIST" and "ARE NOT DEFINITIVE INDICATORS OF WHETHER OR NOT A PROPERTY WILL BE AFFECTED BY A NATURAL DISASTER."
What changed on the fire question in 2025?
This is the detail worth knowing, because it is recent and it is not in most explainers.
Section 1103.2 was amended by Stats. 2024, Chapter 80, Section 19, effective January 1, 2025. Two things changed. The fire item now reads "A HIGH or VERY HIGH FIRE HAZARD SEVERITY ZONE," where it previously captured only very high. And the response options expanded from a plain yes and no to four boxes: high FHSZ in a state responsibility area, very high FHSZ in a state responsibility area, and very high FHSZ in a local responsibility area.
There is a wrinkle that shows how fresh this is. The trigger provision at Civil Code section 1103 subdivision (c)(3) still refers only to a "very high fire hazard severity zone." The form was updated and the trigger clause was not conformed. Cite the form for the high-or-very-high language.
Why did the fire zones change, and did Los Angeles change?
CAL FIRE's Office of the State Fire Marshal rebuilt the maps. Its fire hazard severity zones page states that state responsibility area mapping was completed at the end of 2023 and "went into effect in April 2024," with the local responsibility area maps rolled out in four phases across February and March 2025.
Los Angeles County received its recommended maps on March 24, 2025. The Los Angeles Fire Department published notice confirming the City of Los Angeles was included and adding that "The LAFD estimates an increase in the number of parcels that will be affected by the newly issued FHSZ maps."
One structural point matters here. Government Code 51179(b)(3) says a local agency "shall not decrease" the hazard level the State Fire Marshal recommends, and "may only increase" it. The ratchet turns one way. A city cannot map its way out of a very high designation.
Who is responsible if the disclosure is wrong?
Usually nobody you can reach, which surprises people.
Civil Code 1103.4(b) provides that delivery of the required information by a public agency or a qualifying third party "shall relieve the seller, seller's agent, and buyer's agent of any further duty under this article with respect to that item of information." The seller side orders a report from a natural hazard expert, and the duty shifts.
The condition is good faith in selecting that provider. Civil Code 1103.7 defines the standard in one sentence: "'good faith' means honesty in fact in the conduct of the transaction." Note what that is not. It is not a duty to verify the report, and not a warranty of accuracy.
The expert's own exposure is narrow too. Under 1103.4(c) the expert "shall not be responsible for any items of information or parts thereof, other than those expressly set forth in the statement."
There is one place the seller's judgement still bites. Under 1103.2(b), if a map is not of sufficient accuracy or scale for a reasonable person to tell whether the property is inside a zone, the seller or agent "shall mark 'Yes'." A borderline parcel is supposed to be disclosed as inside, not outside.
Can I back out after receiving the report late?
Sometimes, and the window is short. Civil Code 1103.3(c) gives a buyer who receives a disclosure or a material amendment after executing an offer:
| Delivery method | Days to terminate |
|---|---|
| In person | 3 days |
| Deposit in the mail | 5 days |
| Electronic record, where agreed | 5 days |
Two limits worth being precise about. This terminates the offer, it does not unwind a closed sale. And it only runs if delivery came after the offer was executed, which is why sloppy timing on the seller side occasionally hands a buyer an exit nobody intended.
Waiving the article does not work. Civil Code 1103(d): "Any waiver of the requirements of this article is void as against public policy."
Does a very high fire zone create ongoing duties?
Yes, and the governing statute depends on which responsibility area you are in. Getting this backwards is the most common error in local coverage.
Property in a state responsibility area falls under Public Resources Code 4291. Property in a locally designated very high fire hazard severity zone falls under Government Code 51182. Most Los Angeles County and City of Los Angeles parcels are local responsibility area, so 51182 is the one to read.
It requires maintaining 100 feet of defensible space, more intense fuel reduction between 5 and 30 feet, removing tree portions within 10 feet of a chimney outlet, keeping vegetation adjacent to the building free of dead wood, and keeping the roof clear of vegetative debris.
Is Zone 0 in effect yet?
Not as of August 2026, despite plenty of coverage implying otherwise.
Public Resources Code 4291(g) contains the delay switch. The ember-resistant zone requirement "shall not take effect for new structures until the board updates the regulations ... and the guidance document," and then takes effect for existing structures "three years after the effective date for the new structures." The Board of Forestry and Fire Protection approved a final draft on August 19, 2026, but the package still has to clear the Office of Administrative Law before publication.
So the honest position for a buyer today: Zone 0 is coming, phased, and not yet enforceable. Budget for it on a hillside purchase. Do not let anyone tell you it is already the law.
What does an NHD report cost and who orders it?
Standard residential reports run roughly $70 to $100 in California, with wildfire-specific add-on reports priced higher. The statute puts the delivery duty on the seller and the seller's agent under 1103.2(a) and 1103.3(a), so in practice the seller side orders it.
One restriction people misuse: Civil Code 1103.2(g) says the disclosure "shall not be used by any other party, including, but not limited to, insurance companies, lenders, or governmental agencies, for any purpose." Your NHD is not an insurance document. If you want to know whether the property is insurable and at what price, get a quote in writing during your contingency period. In fire-exposed parts of the county that quote, rather than the disclosure, is the number that decides whether the deal works.
For older housing stock the hazard form pairs with the retrofit obligations covered in retrofits required before selling a house in Los Angeles, and buyers of pre-1980 multifamily should read the Burbank soft-story retrofit deadlines alongside it.
Q: Is the natural hazard disclosure the same as a home inspection?
No. The NHD reports map positions only. It says nothing about the roof, the foundation, the sewer lateral or the electrical panel. A property can come back clean on all six zones and still have serious physical defects.
Q: Does every California home sale require an NHD?
No. Civil Code 1103.1 lists ten exempt categories, including sales by court order, foreclosure sales, transfers between coowners, transfers to a spouse or close relative, and transfers to or from a government entity. Trust and probate sales are exempt, with an exception where a natural person trustee of a revocable trust was a former owner or recent occupant.
Q: What is the difference between a state and local responsibility area?
It describes who is legally responsible for wildfire protection, the state or the local agency. It matters for buyers because the ongoing defensible space statute differs, Public Resources Code 4291 for state responsibility areas and Government Code 51182 for locally designated very high zones.
Q: Can I rely on the NHD for flood insurance decisions?
No, and the statute forbids that use. The form flags whether FEMA maps place the parcel in a Zone A or V special flood hazard area, which affects lender requirements, but pricing and availability come from an insurance quote.
Q: The seller ticked "do not know" on flooding. What now?
Two of the six items allow a "do not know and information not available from local jurisdiction" response. Treat it as an open question rather than a no, and order your own review during the contingency period.
