Selling a home involves more than preparing the property and finding the right buyer. Sellers must also disclose information that could affect a buyer’s safety, insurance, future improvements, and decision to purchase. In California, the Natural Hazard Disclosure—commonly called the NHD report—plays an important role in that process.
For homeowners in Westlake Village, Agoura Hills and Thousand Oaks, understanding this report is especially valuable because fire hazards, hillsides, flood zones and local requirements can vary from one property to the next.
A hazard designation does not necessarily mean something is wrong with your home. However, certain findings can trigger additional disclosures, inspections, or compliance work.
What Is an NHD Report?
An NHD report identifies whether a property falls within certain officially mapped natural hazard areas. Its core disclosures cover:
- Special flood hazard areas designated by FEMA.
- Potential flooding from dam failure, based on inundation maps.
- High or Very High Fire Hazard Severity Zones.
- Wildland areas with substantial forest-fire risks and hazards.
- Earthquake fault zones.
- Seismic hazard zones, including earthquake-induced landslide and liquefaction areas.
Liquefaction occurs when certain water-saturated soils lose strength during earthquake shaking. A landslide designation identifies areas where earthquake-related slope movement may occur. These maps identify potential hazards; they do not predict whether a particular home will experience damage.
Why Is It Required When Selling Your Home?
California law requires applicable natural hazard disclosures in covered real estate transfers. Sellers commonly use a professional NHD company to research the maps and prepare the disclosure package.
The legal obligation is to provide the required disclosures; it is not simply a requirement to purchase a particular commercial report. The completed Natural Hazard Disclosure Statement helps buyers understand mapped risks before proceeding with their purchase. Some transfers have exemptions, which should be evaluated individually.
An NHD report also does not replace the seller’s other disclosure obligations. Known flooding, drainage problems, slope movement, fire damage or other material conditions must still be addressed in the appropriate disclosures. A report showing that a home is outside a mapped hazard zone does not establish that the property has no risk.
What Must the Seller Do With the Results?
The answer depends on the finding. A “yes” on an NHD report does not automatically require repairs, an engineering inspection or a price reduction. Some findings primarily require disclosure; others connect to separate laws requiring action.
If the Property Is in a High or Very High Fire Hazard Zone
For covered sales, California Civil Code Section 1102.19 requires defensible-space compliance documentation or an appropriate written buyer agreement under the applicable rules. Local ordinances determine important details, including inspections and correction deadlines.
A defensible-space inspection evaluates vegetation and other conditions affecting wildfire exposure. If deficiencies are found, the seller should obtain the written correction requirements and establish how compliance will be completed and documented. A private agreement does not prevent the fire authority from enforcing existing requirements.
Additional home-hardening disclosures apply to covered homes built before January 1, 2010 in High or Very High Fire Hazard Severity Zones. These include known vulnerable features and, beginning July 1, 2025, disclosure of which listed low-cost retrofits were completed during the seller’s ownership. This disclosure requirement does not itself impose a blanket obligation to complete every retrofit. Separate code requirements or enforcement orders may still apply.
If the Property Is in a Flood or Dam-Inundation Zone
The seller must disclose the applicable designation. The NHD designation itself does not order the seller to floodproof the home or obtain a drainage inspection.
Nevertheless, known flooding, water intrusion and drainage problems require attention in the seller’s disclosures. Buyers should investigate insurance and financing implications early; the statutory disclosure warns that mapped hazards can affect insurance and future development.
If the Property Is in a Fault, Landslide or Liquefaction Zone
The seller must disclose the mapped designation. A seismic hazard designation does not automatically require a geological investigation solely because an existing home is being sold.
A site-specific geological or engineering investigation may become necessary for development or permitting. For a resale involving visible movement, significant cracking or a known slope concern, specialist evaluation may also be appropriate to understand the condition and support accurate disclosures.
Local Requirements: The Property’s Jurisdiction Matters
A “Westlake Village” mailing address does not establish which city, county or fire authority governs the property. Confirm the parcel’s actual jurisdiction before deciding which inspection process applies.
Property location | Fire inspection process to verify |
|---|---|
City of Westlake Village, Los Angeles County | Los Angeles County Fire Department’s AB 38 process for qualifying properties. |
Agoura Hills and nearby Los Angeles County communities | Los Angeles County Fire Department’s process, based on the parcel’s designation and jurisdiction. |
Thousand Oaks, including Westlake-area properties within Thousand Oaks | Ventura County Fire Department requirements for qualifying properties, including the rules effective January 1, 2026. |
Nearby unincorporated areas | Confirm the county, responsible fire agency and parcel-specific requirements before ordering inspections. |
The Los Angeles County Fire Department provides an AB 38 inspection request process. Ventura County Fire Department’s published guidance specifically includes Thousand Oaks and unincorporated Ventura County within its service area.
Los Angeles County: Westlake Village and Agoura Hills
For qualifying properties, request the defensible-space inspection early. Los Angeles County’s inspection instructions describe providing a passing report from the six months preceding the sales contract.
If the property does not pass, the inspector identifies necessary work and the reinspection process. The department’s instructions also describe a written buyer agreement to obtain compliance within one year after closing when compliance documentation is unavailable. Confirm that this option fits the property’s circumstances and any existing enforcement notices.
Ventura County: Important Requirements Effective January 1, 2026
Ventura County Fire Protection District’s Guideline 427 establishes stricter procedures for covered residential transfers in High or Very High Fire Hazard Severity Zones within its jurisdiction:
- A Fire District defensible-space inspection is required before transfer.
- An approved inspection within the applicable six-month period may satisfy the requirement; obtain the approval report.
- Identified violations generally must be corrected within 30 days of the correction notice or before escrow closes, whichever comes first.
- After corrections, the seller must request reinspection and obtain approval.
- If corrections cannot reasonably be completed before closing, an eligible written agreement may assign completion to the buyer within 60 days after closing. The agreement must be provided to the Fire Prevention Bureau before closing.
- An existing Notice to Abate Fire Hazard has separate deadline provisions that must be followed.
Do not assume that a general one-year buyer agreement satisfies Ventura County’s local requirements.
What Other Inspections Should Sellers Plan For?
There is no single inspection checklist that applies to every home in these communities. Requirements depend on the parcel, property type, existing notices, purchase agreement and lender.
Fire inspection: Required for qualifying properties under the applicable defensible-space rules described above. The NHD report identifies mapped hazards; it does not replace the physical compliance inspection.
Home and specialist inspections: General home, roof, HVAC, electrical, plumbing, sewer-camera, pool, chimney, foundation and drainage inspections may be appropriate based on the property’s condition and the contract. Homes with private septic systems, wells, hillside improvements or retaining walls need particular attention to those features and any applicable agency requirements. These are not all automatically seller-required inspections merely because a hazard appears on the NHD report. California DRE encourages buyers to investigate the home’s major systems and use qualified professionals.
Termite inspection: California does not universally require a structural pest inspection before a sale. A purchase agreement or lender may require one, and applicable reports must be delivered as required.
City records and resale requirements: Thousand Oaks discontinued its mandatory residential building-records resale report requirement on June 2, 2023, although records remain available. Also, the City of Los Angeles 9A report is a Los Angeles city requirement; it does not apply to Westlake Village or Agoura Hills simply because they are in Los Angeles County.
Before listing, have your agent confirm the complete address-specific checklist with the relevant building department, fire authority and, where applicable, environmental health agency. Include existing code notices, permit issues and required safety compliance in that review.
Prepare Early for a Smoother Sale
Ordering the NHD report early gives sellers time to understand the findings, schedule any required fire inspection and address correction notices before they interfere with escrow. It also gives buyers more time to investigate insurance and property-specific concerns.
