Special flood hazard area
Is the property in one of FEMA's zones with a 1% or greater chance of flooding in any year (Zones A and V)? Lenders often require flood insurance there.

What's covered
Six mapped hazards every California seller has to disclose.
California Civil Code §1103 requires sellers and their agents to tell buyers whether a property lies in any of these state or federally mapped zones. Your report makes each determination and shows where it came from.
Dam inundation area
Could the property flood if an upstream dam failed? The state maps these areas of potential flooding from dam inundation studies.
Mapped by the CA Department of Water Resources
Very high fire hazard severity zone
The State Fire Marshal rates fire hazard as Moderate, High or Very High based on expected fire behavior. Maps for local responsibility areas were updated in 2025.
Mapped by the Office of the State Fire Marshal
Wildland area (State Responsibility Area)
Is the property in wildland where the State of California is primarily responsible for fire protection? These areas carry their own fire-prevention requirements.
Mapped by CAL FIRE
Earthquake fault zone
Is the property inside an Alquist-Priolo Earthquake Fault Zone, drawn around active faults where the ground surface could rupture?
Mapped by the California Geological Survey
Seismic hazard zone
Is the property in ground mapped for possible liquefaction or earthquake-induced landslides? These zones can require site studies before building.
Mapped by the California Geological Survey
Hazard maps are estimates. Being in or out of a zone doesn't predict whether a property will be damaged, and an NHD report isn't a home inspection, a geologic study or an insurance decision.

Wildfire disclosures
Fire-zone disclosures, flagged up front.
The State Fire Marshal released updated Fire Hazard Severity Zone maps for local responsibility areas in 2025. Homes in high and very high zones can carry added disclosure requirements, including the Fire Hardening and Defensible Space disclosure under AB 38.
The report preview now flags when that disclosure may be required, so it's handled at listing instead of discovered in escrow.

What is a Natural Hazard Disclosure (NHD) report?
California law requires sellers and their agents to tell buyers whether a property sits in certain mapped hazard zones (Civil Code §1103). An NHD report checks the official maps for the property and prepares the Natural Hazard Disclosure Statement, so the disclosure is accurate and documented.
Who orders the NHD, and when?
The disclosure goes to the buyer as soon as practicable before the transfer of title, so most listing agents order it when the property goes on the market. That way it's ready to hand over with the rest of the seller's disclosures.
How fast will I get my report?
Most reports are delivered in about a minute after you order, and you can check the real-time hazard maps right away.
Does an NHD tell me everything about a property's risk?
No. It reports whether the property is inside officially mapped zones. Maps are estimates: they don't predict whether a property will be damaged, and an NHD isn't a home inspection, a geologic study or an insurance decision. For property-specific questions, talk to the right licensed professional.
What changed with the new ordering platform?
Ordering now happens on a single page, the report preview flags when the Fire Hardening and Defensible Space disclosure may be required, and your order history and downloads are all in one place. The first time you sign in, we'll email you a link to set a new password.
I'm a landlord. Do I need a tenant flood disclosure?
California requires residential landlords to disclose certain flood-hazard information to tenants. The Tenant Flood Report shows whether the rental is in a special flood hazard area or an area of potential flooding, so what you disclose is accurate.
Can I get a copy of a past report?
Yes. Sign in and your order history and report downloads are there. Trouble signing in? Email support@logicnhd.com.
