Buying Flood Insurance for a Coastal Second Home: What to Know First
Learning goal: Know why a coastal second home generally needs separate flood insurance, the NFIP's limits and waiting period, and what to check before storm season.
Short answer
Plan ahead. Most home policies don't cover flood damage, so a coastal second home generally needs a separate flood policy. NFIP building coverage goes up to $250,000 and contents up to $100,000, and a new policy usually takes effect 30 days after purchase, with exceptions such as buying it when you get a mortgage.

The Fuller Picture
Coastal homes face storm surge and rising water that a homeowners policy typically excludes. Flood insurance is a separate decision with its own limits and timing, and the 30-day wait means it can't be bought as a storm approaches.
Key Takeaways
- FEMA: "Building policies cover up to $250,000 of flood damage," and contents policies up to $100,000 "for belongings kept inside your home."
- A new NFIP policy generally takes effect 30 days after purchase. FEMA lists exceptions: "There is no wait if you buy flood insurance while making, increasing, extending or renewing a mortgage."
- The Texas Department of Insurance: "Most flood policies have a 30-day waiting period before kicking in so don't wait for an approaching storm."
- Building and contents are separate coverages; buy both if you want both covered.
- If a home's value is above NFIP limits, private flood policies may offer more; compare terms.
Real-World Example
Buying in March vs August
The Lees close on a beach condo in March with a mortgage. Buying NFIP flood coverage at closing, they'd have no waiting period under FEMA's mortgage exception. Their neighbors, who bought years ago without flood insurance, decide to buy it in August when a storm is forecast. Their new policy would generally take effect 30 days later, after the storm. Same street, same storm, very different outcomes, decided by timing.
Common Mistakes
- Waiting for a forecast storm to buy flood insurance.
- Buying building coverage only and assuming that includes belongings.
- Assuming the homeowners policy covers storm surge.
