Earthquake risk in San Antonio and Bexar County is very low. Earthquake insurance is generally not considered necessary for most homeowners in this area. Standard homeowners policies do not cover earthquake damage, but given the minimal risk, most experts recommend skipping this endorsement in South Texas.
Earthquake Risk in San Antonio
San Antonio sits in a region with very low seismic activity. The USGS rates Bexar County at minimal risk for earthquakes. The nearest fault zones are hundreds of miles away. Most San Antonio homeowners will never experience earthquake damage in their lifetime.
What Standard Homeowners Insurance Covers
Standard HO-3 policies explicitly exclude earthquake damage. If you want coverage, you must purchase a separate earthquake endorsement or policy. The deductible is typically 10-20% of the dwelling limit, making it a high-cost, high-deductible product.
Cost of Earthquake Insurance
In low-risk areas like San Antonio, earthquake insurance is relatively cheap ($100-$300 per year), but the high deductible means it only pays out for catastrophic damage. For most homeowners, that trade-off does not make financial sense compared to other priorities.
When to Consider It
If you have an extraordinary risk tolerance, a very high-value home, or a lender that requires it (rare in Texas), earthquake insurance is available. For the typical San Antonio homeowner, the premium is better spent on wind/hail coverage, flood insurance, or an umbrella policy.
