In This New Hampshire Flood Insurance Guide:
Is New Hampshire Flood Insurance Required?
Standard homeowners insurance does NOT cover flood damage in New Hampshire or any other state. This is one of the most common and costly misconceptions among homeowners. If your home is damaged by flooding — whether from a hurricane, heavy rain, river overflow, or storm surge — your standard HO-3 policy will not pay for repairs.
If you have a federally backed mortgage (FHA, VA, USDA, or conventional through Fannie Mae/Freddie Mac) and your property is in a FEMA-designated Special Flood Hazard Area (SFHA), flood insurance is mandatory. Your lender will require you to maintain flood coverage as a condition of the loan.
Even if flood insurance is not required for your property, it is strongly recommended. FEMA data shows that approximately 25% of all flood claims come from properties outside high-risk flood zones. Just one inch of floodwater can cause over $25,000 in damage.
FEMA Flood Zones in New Hampshire
New Hampshire has both riverine and coastal flood zones designated by FEMA. High-risk zones (A and V zones) exist along major river corridors including the Connecticut, Merrimack, Saco, and Piscataqua Rivers, as well as the short Atlantic coastline in Rockingham County. FEMA is actively updating Flood Insurance Rate Maps across the state through the Risk MAP process.
Areas in New Hampshire with the highest flood risk include:
- Grafton County
- Coos County
- Carroll County
- coastal Rockingham County
- Merrimack River valley
- Connecticut River valley
- Keene
- Claremont
Notable flood events in New Hampshire’s history include:
- Great New England Flood (1927)
- Connecticut River Flood (1936)
- Great Hurricane Flood (1938)
- Mothers Day Flood (2006)
- Nor’easter Flood (2007)
These events underscore why New Hampshire flood insurance is essential protection.
NFIP Flood Insurance Coverage & Costs in New Hampshire
The National Flood Insurance Program (NFIP), administered by FEMA, is the primary source of flood insurance in New Hampshire. NFIP policies are sold through private insurance agents but are backed by the federal government.
The average annual NFIP premium in New Hampshire is approximately $1,140. This is above the national average NFIP premium of approximately $900 per year.
NFIP residential coverage limits:
| Building Coverage (max) | $250,000 |
| Contents Coverage (max) | $100,000 |
| Deductible Options | $1,000 – $10,000 |
| Waiting Period | 30 days for new NFIP policies, 0 if at closing |
| Basement Coverage | Limited — structural elements only |
Important NFIP limitations: NFIP policies do not cover finished basements, landscaping, currency, precious metals, or temporary housing costs. Maximum residential building coverage is $250,000 — homeowners with properties valued above this should consider a private flood policy or excess flood coverage.
Private Flood Insurance in New Hampshire
In addition to the NFIP, private flood insurance is available in New Hampshire from companies including:
- Neptune Flood
- Selective Flood
- EZ Flood
- Palomar Specialty
- Wright Flood
Private flood policies may offer higher coverage limits (above the $250,000 NFIP cap), shorter waiting periods, replacement cost coverage, and additional living expense (ALE) coverage that NFIP does not provide.

How to Save on New Hampshire Flood Insurance
Flood insurance costs vary significantly based on your property’s flood zone, elevation, and coverage options. Here are proven strategies to reduce your premium:
- Elevation Certificate: Documents your home’s elevation relative to the Base Flood Elevation. If above BFE, you may qualify for significantly lower NFIP rates.
- Compare NFIP vs private flood: Private flood insurers may offer lower rates for properties in certain risk zones.
- Higher deductible: Increasing your deductible from $1,000 to $5,000 or $10,000 can reduce your premium substantially.
- Flood mitigation improvements: Flood vents, elevated utilities, and sump pumps can qualify you for lower rates.
- Preferred Risk Policy: Properties in moderate-to-low risk zones (Zone B, C, or X) may qualify for rates as low as $300-$500/year.
- Community Rating System (CRS): Communities in FEMA’s CRS program give all policyholders a 5-45% discount.
