Practical next steps

Simple things homeowners in ZIP 08558 can do with this information.

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.
Ask about wind mitigation credits. Features like hurricane straps, a newer roof and impact-rated windows or shutters can lower premiums. Ask your insurer which upgrades earn a discount and what paperwork it needs.
Prepare for freezing weather. Burst pipes are a common winter claim. Insulating exposed pipes, keeping heat on while away and knowing where your main water shut-off is all help.
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.

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.
