Flood Insurance in Montana

Spring snowmelt drives Montana's flood season, and standard homeowners policies do not cover flood damage. Here is how flood insurance works in Montana, 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 is available in most parts of Montana. 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. The Montana Commissioner of Securities and Insurance notes there is a 30-day waiting period for an NFIP policy before coverage 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 is the second option. The CSI notes that private coverage may be available and may be more affordable than the NFIP depending on your circumstances. Contact a licensed insurance agent to compare both.

Montana-specific rules and resources

Montana has no state-specific flood insurance program. The notable state effort is the Commissioner of Securities and Insurance's recurring flood insurance awareness campaign, timed to the spring snowmelt season that drives Montana flooding. The CSI's message: properties near rivers, creeks, low-lying underpasses, and land with drainage issues face the greatest risk, and residents should have multiple ways to receive flooding alerts.

The CSI's flood guidance notes two practical points. First, NFIP policyholders may be eligible for up to $1,000 in loss-avoidance reimbursement for supplies bought when flooding is imminent, such as sandbags, plastic sheeting, and lumber. Second, federal law requires flood insurance for federal or federally related financial assistance on buildings in Special Flood Hazard Areas. For help, the CSI's helpline is 800-332-6148 or 406-444-2040.

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. If you believe FEMA's map is wrong for your property, a FEMA Letter of Map Amendment (LOMA) is the formal way to challenge it.

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 Montana?

Usually not. Montana's Commissioner of Securities and Insurance notes that standard homeowners insurance policies typically do not cover flood damage. You need a separate flood policy.

What is loss-avoidance reimbursement?

NFIP policyholders may be eligible for up to $1,000 toward supplies bought when flooding is imminent, such as sandbags, plastic sheeting, and lumber. It is meant to reduce the damage before the water arrives.

When is Montana's flood season?

Spring, driven by snowmelt. The CSI times its flood insurance awareness campaign to the melt season and urges property owners to buy coverage, set up multiple flood alert methods, and keep emergency supplies ready well before it starts.
