San Mateo Earthquake Insurance
San Mateo is 7 miles from the San Andreas Fault — close enough that a major quake will cause serious damage across the city. The 1906 earthquake devastated the Peninsula. Your homeowners policy won't pay for any of it. Earthquake insurance is a separate policy, and in San Mateo, it's essential.
What San Mateo Homeowners Face
7 Miles from San Andreas
San Mateo sits well within the damage zone of a major San Andreas event. The 1906 quake caused widespread destruction across the Peninsula. The USGS projects significant ground shaking in San Mateo during the next major event.
Variable Soil Conditions
Bay-side San Mateo (near 101) has softer soils with higher liquefaction potential. Hillside areas in Baywood sit on more stable ground. Your location within the city significantly affects your earthquake risk.
Mixed Housing Stock
San Mateo's homes range from pre-1950 bungalows to modern builds. Older homes without seismic retrofitting face higher vulnerability — unreinforced foundations, cripple walls, and heavy chimneys.
Earthquake Insurance in San Mateo
Earthquake insurance covers damage from ground shaking, liquefaction, and post-quake fire — everything your homeowners policy excludes. In San Mateo, the question isn't whether to buy earthquake insurance. It's how much coverage and what deductible you can afford. We help you find that balance.

What Your San Mateo Property Is Really Worth to Insure
With a median home value of $1.7M in San Mateo, the financial exposure from an uninsured earthquake is enormous. CEA deductibles of 5-25% on a $900K dwelling policy mean $45K-$225K out of pocket. That's significant — but compare it to losing the entire home with no coverage at all, while still paying the mortgage.
The 5 Most Expensive Earthquake Insurance Mistakes in San Mateo
Paul's Take“Seven miles from the San Andreas Fault. That's San Mateo. People think that's a comfortable distance — it's not. When the 1906 quake hit, the Peninsula was devastated. When Loma Prieta hit in '89, homes 60 miles from the epicenter were damaged. At 7 miles, you'll feel every inch of it. I tell every San Mateo homeowner the same thing: earthquake insurance is the cost of living on the Peninsula. Budget for it.”
