Earthquake Safety Booklet and Residential Earthquake Hazards Report
Reviewed by Jimi (James) Allyn · Founder, Verity NHD · 37-year real estate professional
Delivery of the state earthquake safety booklet, plus — for certain pre-1960 homes — a completed Residential Earthquake Hazards Report identifying known weaknesses.
What it is
California's earthquake disclosure scheme has two layers: a booklet everyone gets, and a report some sellers must complete.
The booklet. Civil Code sections 2079.8 and 2079.9 direct that the Homeowner's Guide to Earthquake Safety, developed by the California Seismic Safety Commission, be delivered to the buyer in covered residential transactions. Delivery of the booklet satisfies the disclosure obligation as to its contents — you are not expected to teach seismic engineering, only to put the state's guide in the buyer's hands. A separate Commercial Property Owner's Guide to Earthquake Safety serves commercial and industrial transfers.
The report. Government Code section 8897.1 requires the Homeowner's Guide to Earthquake Safety and a completed Residential Earthquake Hazards Report for any residential dwelling built before January 1, 1960, with one to four units, of conventional light-frame construction as that term is defined in Chapter 25 of the 1991 Uniform Building Code. The report is a structured questionnaire about known seismic weaknesses: an unbraced water heater, an unbolted sill plate, unreinforced masonry walls or chimneys, a cripple wall without bracing, a house on a post-and-pier foundation.
On the commercial side, Government Code section 8875.6 requires the Commercial Property Owner's Guide to Earthquake Safety for any unreinforced masonry building with wood-frame floors or roofs built before January 1, 1975. The current Homeowner's Guide edition is the 2020 edition from the Seismic Safety Commission.

Who signs it
The seller completes and signs the Residential Earthquake Hazards Report where it applies, answering from actual knowledge — "unknown" is an available and honest answer for a condition inside a wall. The buyer acknowledges receipt of the booklet and, where applicable, the report.
Agents deliver the booklet and should confirm the build year from a reliable source rather than a listing sheet, since the pre-1960 trigger turns on it. The seller is not required to hire an engineer; the disclosure is about known conditions, not a structural assessment.
When it's due
With the seller's disclosure package, as soon as practicable before transfer of title. The booklet is a delivery item, so it belongs in the same package as the TDS and NHD statement.
The Residential Earthquake Hazards Report takes the seller a little time and sometimes a look in the crawl space, so it should not be left to the final days of escrow. Note also that the same conditions the report asks about overlap with the water heater bracing certification, so the two are efficient to handle together.
If it's missed
Failure to deliver the booklet is a compliance defect; failure to complete a required Residential Earthquake Hazards Report is the more consequential one, because it goes to specific known conditions. A buyer who discovers an unbraced cripple wall that the seller knew about has an ordinary nondisclosure claim, with the statutory form as evidence of what should have been reported.
There is a related insurance dimension. Seismic retrofit status can affect earthquake coverage availability and pricing, and a buyer who relied on silence may argue they were denied the chance to price that risk.
Common mistakes
Delivering the booklet and skipping the report. For qualifying pre-1960 homes they are two separate obligations.
Answering "no" instead of "unknown." If nobody has looked under the house, say so.
Using the residential guide for a commercial transfer. There is a separate commercial guide.
Confusing this with the NHD statement's seismic zones. The NHD reports mapped fault and seismic hazard zones. This disclosure is about the building.
Assuming a remodel resets the build year. It does not.
