Why a seller cares

Earthquake coverage is separate from homeowners insurance and mostly optional. In an earthquake zone, a buyer may ask whether the home is retrofitted and what coverage costs, and the natural hazard disclosure names the zone.

A simple example

Your California home was bolted to its foundation in 2015. The buyer asks for the retrofit paperwork and a quote for earthquake coverage.

Earthquake insurance: a simple example
What the buyer weighsWhat helps
The cost of coverageA retrofit certificate lowers it
The deductibleOften 10% to 20% of the dwelling value
Whether to carry it at allTheir call; lenders rarely ask for it

Earthquake insurance is the buyer's choice, and the home's retrofit is what changes the price of it.
