Natural Hazard Disclosure Statement
California is one of the most geologically and environmentally complex states in the country. Earthquakes, wildfires, floods, landslides. The risks are real, and buyers have a right to know about them before they sign. The Natural Hazard Disclosure Statement, or NHD, is the form that makes that happen. It's state-mandated, seller-obligated, and one of the first disclosures that needs to be ordered and delivered in any residential transaction. If you're listing a property in California and haven't ordered an NHD yet, stop what you're doing.
Why This Document Matters
California Civil Code Section 1103 requires sellers of residential property to disclose whether a property falls within specific natural hazard zones designated by state and federal agencies. This isn't optional. It's not a best practice. It's the law.
The NHD protects buyers by giving them material information about the property's exposure to natural hazards before they remove contingencies or close escrow. It also protects sellers (and you, their agent) by creating a documented record of disclosure. If a buyer later claims they didn't know the property was in a fire hazard zone, a properly delivered NHD is your defense.
Real talk: skipping or delaying this disclosure is one of the common transaction coordination mistakes that can expose everyone involved to liability.
How It Works
Unlike most disclosure forms, the NHD is not something the seller fills out themselves. It's prepared by a licensed third-party NHD company that cross-references the property's location against state and federal hazard zone maps. The seller pays for the report. The agent typically orders it.
The process is straightforward:
- You order the report from an NHD provider (TDS, ProNatura, JCP, Disclosure Source, and similar companies are common in California)
- The provider checks the property address against current hazard zone maps
- The report comes back with yes/no determinations for each statutory hazard category
- The seller reviews and signs it
- It gets delivered to the buyer as part of the disclosure package
Most NHD companies turn reports around quickly, often within 24 to 48 hours. Order it at listing so it's ready to go the moment you have an accepted offer. Don't wait. Buyers expect disclosures fast, and delays can create friction right out of the gate.
Key Sections Explained
The NHD covers six statutory hazard categories required under California law. Here's what each one actually means:
Special Flood Hazard Area (FEMA): This identifies properties in FEMA-designated flood zones where federal flood insurance may be required. These are areas with a 1% or greater annual chance of flooding, also called the 100-year floodplain.
Dam Inundation Zone: Indicates whether the property sits in an area that could be flooded if a nearby dam fails. The California Department of Water Resources maintains these maps.
Very High Fire Hazard Severity Zone: Designated by CAL FIRE for properties in local responsibility areas. If you're selling anywhere near the hills, the urban-wildland interface, or coastal shrubland, there's a real chance this box gets checked.
Wildland Fire Area: This one applies to properties in state responsibility areas, as determined by the Board of Forestry. Different from the Very High Fire Hazard Severity Zone, though buyers often confuse the two.
Earthquake Fault Zone (Alquist-Priolo): Identifies properties within 50 feet of an active fault trace as mapped by the California Geological Survey. New construction is generally prohibited in these zones, but plenty of existing homes sit within them.
Seismic Hazard Zone: Covers areas with elevated risk of earthquake-triggered ground failure, including liquefaction and landslide zones. Also mapped by the California Geological Survey.
Beyond these six, a good NHD report from a reputable provider will include supplemental disclosures covering things like Mello-Roos districts, supplemental property tax information, airport influence areas, and various environmental hazards. That additional data isn't part of the statutory NHD form itself, but it's genuinely useful and buyers will ask about it.
Common Mistakes to Avoid
Using outdated reports. NHD reports aren't evergreen. FEMA updates flood maps. The state updates fire severity zones. An NHD ordered two years ago for a listing that fell through is not a valid disclosure for your current transaction. Order a new one.
Not ordering a new report after FEMA map updates. FEMA's flood map revisions can change a property's flood zone designation entirely. A property that wasn't in a Special Flood Hazard Area six months ago might be now, or vice versa. This matters for insurance, financing, and buyer decision-making.
Failing to deliver before close of escrow. The NHD must be delivered to the buyer before the transaction closes. Delivery after the fact is a compliance failure. Make delivery confirmation part of your escrow checklist.
Relying on the seller's knowledge. This is not a form where the seller checks boxes based on what they think they know. Sellers are not geologists. They don't have access to current FEMA maps. That's exactly why third-party NHD companies exist. The seller's knowledge is irrelevant here. What matters is what the maps say.
Pro Tips from a TC
Here's the thing: not all NHD reports are created equal. Some bare-minimum reports just cover the six statutory zones and nothing else. That's technically compliant, but it leaves a lot of useful information out of the disclosure package. Always order from a provider that includes tax and environmental add-ons.
A good report will include:
- Mello-Roos and CFD (Community Facilities District) information
- Supplemental tax disclosures
- Airport influence area disclosures
- Environmental hazard notices
- Military ordnance locations where applicable
Buyers are going to ask about property taxes and special assessments regardless. Having that information in the NHD package upfront saves you from scrambling later.
Also, keep a copy of the delivery confirmation. Whether you deliver disclosures through DocuSign, Glide, or directly through escrow, document that the buyer received the NHD and when. If anything goes sideways after close, that timestamp matters.
If you want to make sure your disclosure coordination process is tight from start to finish, disclosure coordination is one of the things a TC handles as a core part of the job.

Frequently Asked Questions
Q: Who is responsible for ordering the NHD report?
Technically the obligation to disclose falls on the seller, but in practice the listing agent almost always orders the report on the seller's behalf. The seller pays for it. Some brokerages have systems in place to order it automatically at listing. If you work with a TC, they typically track this as part of the listing setup process. If you're not using a TC yet, check out what a TC actually does before your next listing.
Q: Can the same NHD report be used if the listing expires and re-lists?
Not necessarily. If the report is more than a few months old and there have been any map updates in that window, you should order a fresh one. More importantly, even if nothing has changed on the map side, your NHD provider's terms will specify how long the report is valid. Check the expiration date listed on the report itself. When in doubt, order a new one. The cost is minor compared to the exposure of using stale information.
Q: What happens if a property is in a fire hazard zone? Does that kill the deal?
Not automatically. Lots of properties in California are in fire hazard zones, and they sell all the time. What it does affect is insurance. The California FAIR Plan exists as a last-resort insurer for properties that can't get coverage through the standard market, but coverage and pricing have gotten significantly more complicated in recent years. Buyers need time to sort out insurance before removing contingencies, especially in high fire risk areas.
