California Disclosures: TDS, NHD, Material Facts, and Visual Inspection

The TDS addresses property condition. The NHD addresses specified mapped hazards. Known material facts require their own disclosure analysis, and a broker's required visual inspection is a separate duty. A completed form does not erase a known problem.

Start with the transfer, not just the form's name

The statutory Transfer Disclosure Statement applies to specified transfers of residential property improved with one to four dwelling units, subject to exemptions. Identify the transaction and any exemption before deciding that a TDS is required. An exemption from this form does not create blanket permission to conceal known material facts.

When the required TDS is delivered after the buyer's offer, Civil Code section 1102.3 provides a termination period of three days after personal delivery, five days after deposit in the mail, or five days after electronic delivery, exercised by written notice. Do not confuse this statutory right with a differently worded inspection contingency in the purchase agreement.

Mapped hazard and actual damage are different facts

The NHD statutory framework identifies six designated hazard categories, including specified flood, dam-inundation, fire-hazard, wildland-fire, earthquake-fault, and seismic-hazard areas. Apply the current map and statutory category, including the current high or very high fire-hazard classification where applicable. The framework has its own scope and exemptions.

A property can be outside a mapped flood zone yet have known flooding history. Conversely, a property can be in a mapped zone without having suffered flood damage. Answer the location question and the known-condition question separately. A private inspection report does not replace a required hazard disclosure.

Inspection does not mean demolition, but red flags still matter

Civil Code section 2079 imposes a reasonably competent and diligent visual inspection duty on specified brokers in covered one-to-four-unit residential transactions. It does not require dismantling the building, inspecting inaccessible areas, or performing every technical test. Scope limitations are not permission to ignore a visible defect or known information.

Materiality depends on the facts and applicable law. California has special rules for certain sensitive information, including Civil Code section 1710.2's treatment of deaths and HIV/AIDS. Avoid a slogan that either every fact must always be volunteered or every form exemption ends the analysis. Read the specific rule and any direct inquiry.

Apply it, then change one fact

The current hazard map places the home outside the special flood hazard area. The seller knows that the garage floods during heavy rain. May the seller omit that history merely because the NHD map answer is negative?

Reasoning: No. The map classification does not eliminate a known material condition. Disclose the relevant flooding history through the applicable property-condition and material-fact process.

Change one fact: A home inside a designated zone may still require the mapped-hazard disclosure even if it has never flooded. Actual history and mapped location answer different questions.

Keep these distinctions clear

TDS
Property-condition form for covered transfers; check exemptions.
NHD
Specified mapped-hazard disclosures; separate scope and exemptions.
Material facts and inspection
Known facts and covered visual-inspection duties remain distinct.

Check the controlling rule

Current statutes and regulations control over older reference-book descriptions. Read the cited section for transaction-specific conditions and exceptions.

Frequently asked questions

Does a TDS exemption allow the seller to conceal defects?

No. A form exemption is not a blanket exemption from disclosure of known material facts or other applicable duties.

Does an NHD report tell me whether the home has flooded?

Not by itself. It identifies specified hazard classifications. Known flooding history is a separate property-condition fact.
