How flood insurance works
Flood insurance covers damage from rising water: overflowing rivers, storm surge, heavy rain that pools, and mudflow. That includes your home’s structure, foundation, electrical and plumbing systems, furnace and water heater, and (with contents cover) your belongings.
| NFIP | Private flood | |
|---|---|---|
| Building coverage | Up to $250,000 | Often higher limits |
| Contents coverage | Up to $100,000 | Often higher limits |
| Extra living expenses | Not included | Sometimes included |
| Waiting period | Usually 30 days | Often shorter |
| Available to renters | Yes, contents only | Varies |
What it costs
NFIP prices now reflect each home’s individual flood risk (FEMA’s Risk Rating 2.0), so costs vary widely. Figures cited by Kiplinger put the average at about $888 a year. For lower-risk homes with $250,000 of building and $100,000 of contents cover, FEMA’s average was about $673 a year plus a $25 surcharge for a primary residence. Renters’ contents-only cover can start around $99 a year.

- Homes in high-risk flood zones with a federally backed mortgage are required to have it.
- Everyone else should consider it. Flooding happens outside mapped high-risk zones too, and disaster aid is often a loan that must be repaid, not a grant.
- Check your home’s flood risk on FEMA’s flood maps and ask insurers for a quote; low-risk homes are often affordable.
Tips
- Buy early because of the waiting period.
- Add contents coverage; building cover alone doesn’t include your belongings.
- Compare NFIP with private flood for higher limits or living-expense cover.
- Keep an inventory and photos of your home and belongings.
