Practical next steps

Simple things homeowners in ZIP 91730 can do with this information.

Check your flood zone. Look up your address on FEMA's Flood Map Service Center (msc.fema.gov). Standard home policies don't cover flood damage, and flood insurance usually has a 30-day waiting period, so it's worth sorting out before storm season.
Know that earthquake damage is separate. Standard homeowners policies exclude earthquakes. If shaking is a concern where you live, ask about a separate earthquake policy or endorsement and its deductible.
Create defensible space. Clearing dry brush and debris within 30 feet of the house and using ember-resistant vents can lower wildfire exposure. Some insurers and states recognize mitigation work with discounts.
Compare at renewal. Premiums vary widely by ZIP code, home and insurer. Use these averages as a reference point, not a price, and compare a few quotes at renewal.

Historical averages, not a quote. Homeowners figures are inflation-adjusted averages from the U.S. Treasury Federal Insurance Office "Supporting Underlying Metrics" (2018–2022, published January 2025). They cover HO-3/HO-5 policies from participating private insurers and exclude state residual-market plans (such as FAIR plans and Citizens), surplus-lines and flood coverage. Treasury notes that individual ZIP codes can contain data anomalies. Your price depends on your home, coverage and insurer.
