Flood Insurance in Maine

Coastal storm surge, river flooding, and spring snowmelt all reach Maine, and a standard Maine homeowners policy does not cover flood. Here is how flood insurance works in Maine, in plain English.

Your two options: NFIP or private flood insurance

The National Flood Insurance Program (NFIP), run by FEMA, is the federal option and the dominant one in Maine. For homes, it offers up to $250,000 in building coverage and up to $100,000 in contents coverage, sold as two separate coverages. For businesses, up to $500,000 for the building and up to $500,000 for contents. NFIP rates are set by FEMA, so the price does not change with the agent you buy from. There is a 30-day waiting period before a new NFIP policy takes effect. You buy NFIP policies through a licensed insurance agent, and your community must participate in the NFIP for you to be eligible.

Private flood insurance exists, but the Maine Bureau of Insurance describes the state's private flood market as very small. In practice, flood insurance in Maine is overwhelmingly an NFIP product. A licensed agent can tell you whether any private option is available for your property, but expect the NFIP to be the main quote you compare against.

Maine-specific rules and resources

Maine's Bureau of Insurance is unusually direct about the market. It states plainly that the Bureau has no jurisdiction over the NFIP program, and that Maine's private market for flood coverage is very small. That means your flood policy is a federal product bought through a licensed agent, and state regulators cannot step in on NFIP policy disputes the way they can with a homeowners policy.

The Bureau's flood guidance lists the NFIP's maximum coverages and points Mainers to the NFIP at 1-800-427-4661 or FloodSmart.gov, and to the Maine Emergency Management Agency for NFIP information. Separately, Maine's Floodplain Management Program (in the Department of Agriculture, Conservation and Forestry) coordinates the state's NFIP participation, including the local floodplain ordinances that set minimum standards for building in flood-prone areas. If you build or substantially improve a structure in a floodplain, the local ordinance, and the elevation certificate that goes with it, will affect both your permit and your premium.

Maine warning worth hearing. The Bureau notes that FEMA reported more than 40 percent of flood claims between 2014 and 2018 came from outside high-risk flood areas. And do not count on federal aid after a flood: FEMA assistance is targeted at immediate shelter and safety needs, not rebuilding, and most disaster aid arrives as a loan you repay.

Lender rules and the mandatory purchase requirement

The mandatory purchase rule is federal, not state. Under the Flood Disaster Protection Act of 1973, flood insurance is required when a building sits in a Special Flood Hazard Area (the high-risk zone on FEMA's maps) and the loan is backed by the federal government or made by a federally regulated lender. Your lender checks FEMA's maps, and if your property is in a high-risk zone, the lender can require flood insurance as a condition of the loan.

Lenders can also require flood insurance outside high-risk zones, and many do. One Maine-specific wrinkle to know: a lender's flood determination is a horizontal check against the current FEMA map. It cannot be based on elevation data unless FEMA has issued a Letter of Map Amendment (LOMA) for your property based on an elevation certificate. If you dispute the determination, the LOMA process is the formal route.

How flood claims work

The NFIP claims process is the same nationwide. Here is the plain-English version, based on FEMA's claims manual:

Notify your insurer or agent promptly after the flood. Do not wait.
Document everything. Take photos and video of the damage before you clean up, and keep damaged items until the adjuster has seen them.
Prevent further damage. Make temporary repairs and keep receipts for anything you spend protecting the property.
File a signed, sworn proof of loss within 60 days of the flood, with documentation supporting the amount you are claiming. FEMA sometimes extends this deadline after major disasters.
An adjuster inspects the damage, and payment follows once the insurer agrees on the covered amount. If your claim is denied or you disagree with the amount, you can appeal directly to FEMA within 60 days of the denial letter.

If local officials declare your home substantially damaged, your NFIP policy's Increased Cost of Compliance (ICC) coverage can provide up to $30,000 to help bring the building up to current floodplain standards, through elevation, relocation, demolition, or floodproofing.

Quick answers

Does my homeowners insurance cover flood damage in Maine?

No. The Maine Bureau of Insurance notes that flooding is not covered under most property policies. Flood coverage must be purchased separately, usually through the NFIP.

Can Maine's Bureau of Insurance help with an NFIP dispute?

Not on the policy itself. The Bureau states it has no jurisdiction over the NFIP program. NFIP claim disputes go through the insurer's process and then a direct appeal to FEMA, within 60 days of a denial letter.

Do I need flood insurance if my Maine home is not in a high-risk zone?

Federal law only requires it in high-risk zones with a federally backed loan, but FEMA reported that more than 40 percent of flood claims between 2014 and 2018 came from outside high-risk areas. Your lender can also require coverage anywhere.
