The 30-day waiting period: why to buy flood insurance before hurricane season
A new NFIP flood policy usually starts 30 days after you apply and pay. Buy it when a storm is on the map and it's too late. Here's how the wait works.
Updated
A new flood policy from the National Flood Insurance Program usually doesn’t start until 30 days after you apply and pay. That means the day a storm shows up on the forecast is already too late to buy protection for it.
When a storm is coming, the question is always the same: “Can I get flood insurance today?” You can buy it. It just won’t cover that storm. Here’s how the wait works, and the few times it doesn’t apply.
How the 30-day wait works
Under the federal rule (44 CFR 61.11), a new NFIP policy takes effect at 12:01 a.m. on the 30th day after the application date and the payment of the premium. Apply and pay on May 1, and coverage starts May 31.
The same wait applies when you add coverage or raise your limits on an existing NFIP policy. So if you’ve been meaning to increase your contents coverage, that also needs to happen well ahead of a storm.
Why the wait exists
Insurance works when people buy it before they know they’ll need it. If anyone could buy flood coverage the day before the water arrived, only people with a storm already on the way would buy it. The waiting period keeps the program from being used that way.
The exceptions
There are a few situations where the NFIP wait is shorter or doesn’t apply:
- When you’re getting a mortgage. If your first flood purchase is in connection with making, increasing, extending or renewing a loan, coverage can start at the loan closing, as long as you apply and pay at or before closing.
- When your community’s flood map changes. For 13 months after a revised flood map takes effect, a first purchase made in connection with that map change starts the day after you apply and pay.
- After certain wildfires. Where FEMA determines that flooding on federal land was caused or made worse by post-wildfire conditions, a first purchase for an affected private property within 60 days of the fire being contained starts the day after you apply and pay.
If none of these fits, plan on 30 days.
Private flood policies
Private flood insurers set their own waiting periods, and they aren’t all the same as the NFIP’s. Ask, and get the answer in writing on the policy. Don’t assume.
Florida · Switch to
In Florida
The Atlantic hurricane season runs June 1 through November 30, and according to the National Hurricane Center most activity happens between mid-August and mid-October. Count back 30 days from June 1 and you get the beginning of May. That’s the latest I’d want any Florida homeowner or renter thinking about flood coverage for the coming season.
Rainy season floods homes here too, not only hurricanes. A slow-moving storm can drop enough rain to flood streets that have never flooded before.
If you’re with Citizens Property Insurance and your policy now requires flood coverage, Citizens accepts a submitted flood application with proof of payment while the flood policy is pending. Don’t leave it to the renewal week, though. The waiting period still applies to when the flood coverage itself starts.
Illinois · Switch to
In Illinois
The Illinois Department of Insurance has reminded homeowners and renters that flood insurance becomes effective 30 days after it’s purchased, and that in participating communities it can be bought whether or not you’re in a mapped flood hazard area. Heavy rain and fast snowmelt can both bring water in. If your home sits near a river or you’ve had water in the basement before, buy it long before the next storm.
One more Illinois point from the Department: standard flood coverage doesn’t typically cover sewer backup or sump pump problems. That’s a separate add-on to ask about at the same time.
Good to know
- Put a date on your calendar. For Florida, early May at the latest. For anywhere, any time you’re thinking “I should look into flood.”
- Pay promptly. The 30 days count from the application and the premium payment, not from your first phone call.
- Don’t cancel one flood policy before the next has started. A gap restarts the problem.
- Renters can buy flood coverage too, for their belongings. The same wait applies. Renting in Florida.
