It is advisable to still deliver a copy of The Homeowner's Guide to Earthquake Safety Booklet in all real estate transactions even if the property is built after 1960 as it covers the steps to take before, during and after an earthquake.
If the seller is unsure if the property is located in an earthquake zone, the Natural Hazard Disclosure (NHD) report will reveal that. California State law requires the seller to provide the buyer with a Natural Hazard Disclosure statement that designates whether the home they are selling is located in a hazard area. Hazard areas include flood, fire, earthquake fault and seismic hazards zones. The NHD report can be purchased through a third party company and be paid at closing through escrow.
