How Long Is an NHD Report Valid in California?
There's no statutory expiration for NHD reports, but best practice is to order a fresh report for each transaction. Here's why report age matters and when you need a new NHD report.
No explicit expiration in the statute
Civil Code §1103 does not set a shelf life for NHD reports. A properly prepared report is valid for the transaction it was ordered for. However, the statute also requires that the disclosure reflect current conditions — which creates a practical limit on how long an old report remains reliable.
Hazard maps change
Government agencies periodically update their hazard zone maps. FEMA updates flood maps, CAL FIRE revises Fire Hazard Severity Zones, and CGS updates seismic and liquefaction zone designations. A report that was accurate six months ago may not reflect a recent zone reclassification.

Industry standard: fresh report per transaction
Most title companies, escrow officers, and real estate attorneys recommend ordering a new NHD report for each transaction. The cost is modest — see our NHD report pricing guide — and a fresh report eliminates any question about whether the hazard data is current.
Risks of using a stale report
An agent or seller who relies on an outdated report faces exposure if a hazard zone has changed since the report was generated. The buyer could argue they were not properly informed, which creates rescission risk and potential liability for the agent, broker, and seller.
- Map revision missed. A post-report zone change leaves the file contradicted by current maps.
- Post-close litigation. A buyer who later discovers a missed zone has a straightforward failure-to-disclose claim.
- E&O exposure. Carriers scrutinize report age at close; a stale report is a red flag.

Bottom line
While NHD reports don't technically expire, the underlying data can change. Order a fresh NHD report for each transaction — it's the cheapest form of liability protection in the deal.
