How to Read Your NHD Report
A practical guide for agents and clients to interpreting each section of the Natural Hazard Disclosure report and understanding what a 'Yes' or 'No' really means.
What the NHD Report Covers
The Natural Hazard Disclosure Statement is required by California Civil Code §1103 whenever specified residential property is sold. It tells the buyer whether the property lies within any of six statutory hazard zones. Each zone is answered "Yes," "No," or "Map Not Available."
The Six Statutory Hazard Zones
| Zone | Authority | What It Means |
|---|---|---|
| Special Flood Hazard Area | FEMA / Civil Code §1103 | 1% annual flood risk; flood insurance may be mandatory |
| Area of Potential Flooding (Dam Inundation) | Gov. Code §8589.3 | Could flood if an upstream dam fails |
| Very High Fire Hazard Severity Zone | Gov. Code §51178 | Local high-fire zone with defensible-space duties |
| Wildland Fire Area (State Responsibility Area) | PRC §4125 | State bears wildfire suppression responsibility |
| Earthquake Fault Zone | PRC §2622 (Alquist-Priolo) | Near an active surface fault trace |
| Seismic Hazard Zone | PRC §2696 | Risk of liquefaction or earthquake-induced landslide |
Beyond the Six Zones
Most commercial NHD reports also include supplemental disclosures that are commonly bundled with the statutory statement:
- Property tax & special assessments:Mello-Roos Community Facilities Districts (CFDs) and 1915 Bond Act assessments that add to the tax bill.
- Advisories: Megan's Law notice, environmental hazards, airport influence areas, right-to-farm, and mining operations.
- Data sources: a list of the maps and databases consulted, so the buyer can verify the determination.
How to Explain Results to Clients
- A "Yes" is a disclosure of risk, not a defect — but it may affect insurance, financing, and defensible-space obligations.
- "Map Not Available" means the jurisdiction has not published a map; it is neither a "Yes" nor a "No."
- Encourage buyers to review flood-insurance quotes and any Mello-Roos/CFD assessment amounts before removing contingencies.
Fiduciary Best Practice
Deliver the NHD report early in the transaction, document delivery and buyer acknowledgment, and never characterize a hazard determination as "nothing to worry about." Let the report speak for itself and refer clients to specialists (insurers, engineers) for hazard-specific questions.
Bottom Line
The NHD report answers six statutory zone questions plus tax and advisory disclosures. Read every "Yes," understand its practical impact, and deliver and document the report early to protect both your client and your license.
