Earthquake Readiness for SLO County Homeowners: Retrofits, Insurance, and What to Ask
Updated: 2 days ago
The Central Coast is known for easy weather and open space, but it is also earthquake country. The San Andreas Fault runs through the eastern part of San Luis Obispo County across the Carrizo Plain, and other faults run both onshore and offshore. Most days, none of that crosses anyone's mind. It is still worth a little planning, especially for owners of older homes.
Here is what we share with owners and buyers about SLO County earthquake readiness, from the house itself to insurance and the disclosures that come with a sale.
What 2003 taught the county
On December 22, 2003, a magnitude 6.5 earthquake centered in the hills near San Simeon shook the county. The worst damage was in downtown Paso Robles, where an unreinforced masonry building from the 1890s collapsed and two people lost their lives. Other older masonry buildings were badly damaged, and in Atascadero the historic city hall was closed for years of repairs.
The lesson for homeowners is simple: how a building is constructed, and whether it has been strengthened, matters. Most homes here are wood-framed, which tends to flex rather than crumble, but a few specific weak points are worth checking.
FOUNDATION · RETROFIT
Know how your house sits on its foundation
California's Homeowner's Guide to Earthquake Safety lists the weaknesses that cause the most trouble in houses: a frame that is not bolted to the foundation, unbraced crawl space (cripple) walls, pier-and-post foundations, unreinforced masonry chimneys, rooms built over garages, and hillside homes without adequate support. Older wood-frame homes on raised foundations are the classic case to look at. A licensed contractor or structural engineer can tell you what your house has and what it needs.
The state's Earthquake Brace + Bolt program has offered grants toward bolting and bracing qualifying older houses with raised foundations in eligible ZIP codes. Check the program site to see whether your ZIP code and home qualify and when registration opens. If you own an older property, our post on historic homes in SLO County covers upkeep more broadly.
WATER HEATER · QUICK FIXES
Start with the small fixes
Some of the most useful steps take an afternoon, not a construction crew.
Water heater straps. California requires water heaters to be braced, anchored, or strapped, and sellers certify this when a home sells.
Tall furniture. Secure bookcases, dressers, and TVs to wall studs, especially in bedrooms.
Gas shutoff. Know where your gas meter shutoff is, and only turn it off if you smell gas or suspect a leak.
Early warning. The state's MyShake app can send earthquake early warning alerts to phones in California.
INSURANCE · DEDUCTIBLES
Price earthquake coverage, then decide
Standard homeowners policies in California do not cover earthquake damage. Coverage is purchased separately, most often through the California Earthquake Authority via your regular insurance company. CEA deductibles are a percentage of the dwelling coverage rather than a flat amount, and CEA offers premium discounts for older homes that have been properly retrofitted.
Whether to carry it is a personal risk decision. We encourage clients to get a real quote on a real address before deciding. Our guide to homeowners insurance beyond fire walks through the other coverages worth a look.
BUYING · SELLING
What buyers and sellers should look for
The Natural Hazard Disclosure report shows whether a property sits in a mapped earthquake fault zone or seismic hazard zone. More in our post on what California sellers must disclose.
For one-to-four unit homes built before 1960, sellers provide the Homeowner's Guide to Earthquake Safety and disclose known weaknesses it describes.
If a seller says the house was retrofitted, ask for permits, invoices, or engineering documents.
Use the home inspection to look at the crawl space, foundation connections, and chimney condition.
On hillside or bluff-top property, consider what a geologic report can tell you.
Earthquake readiness is mostly unglamorous: a few bolts, a strap, and a conversation with your insurer. It is worth doing before you ever need it.
