The National Flood Insurance Program is currently authorized through December 11, 2026. On September 2, 2026, the Continuing Appropriations and Extensions Act, 2027 extended the program’s authorization past its previous September 30 date, so NFIP continues operating normally until at least December 11. Congress could extend it again before then, as it has many times before. If you own coastal property in Mount Pleasant, Charleston, or along the Grand Strand — or you’re closing on one this fall — here’s what that actually means, separated from what it doesn’t.
This isn’t a new situation. NFIP has been reauthorized through short-term extensions 36 times since 2017 — most recently this September, and it briefly lapsed just this January before being renewed a few days later. Sometimes these resolve in days. In 2025, a lapse ran 43 days. A lapse isn’t certain, and we don’t know how Congress will handle December 11 — but here’s what stays true either way.
Source: Continuing Appropriations and Extensions Act, 2027 (H.R. 6500, Public Law 119-103), Section 139, signed into law September 2, 2026, which extended NFIP authorization from September 30, 2026 to December 11, 2026. See the Congressional Research Service overview of the law.
What Actually Happens If NFIP Lapses
NFIP can’t issue new or renewal policies during a lapse. That’s the core effect. It does not mean coverage disappears overnight for people who already have a policy.
Existing policies generally remain in effect. If you have NFIP flood coverage today, it generally stays active until its expiration date. A lapse in authorization doesn’t cancel your policy.
Claims on active policies may continue to be paid. FEMA can continue paying valid claims on active policies during a lapse, subject to available FEMA funding.
Private flood insurance isn’t directly affected. If your flood coverage is written through a private carrier rather than NFIP, an NFIP authorization lapse doesn’t directly affect your policy. See our NFIP vs. private flood comparison for how the two compare.
If You’re Buying or Selling During a Lapse
This is where a lapse actually creates friction — and where most of the confusion happens.
If NFIP isn’t authorized, no new flood policies can be issued. That matters if you’re closing on a home that needs flood coverage and doesn’t already have it.
But there’s a workaround that keeps most closings on track: if the property already has an active NFIP policy, the seller’s policy can typically be assigned to the buyer by substituting the name on the policy — coverage carries over without a new policy having to be issued. This is the detail most homeowners (and some agents) don’t know, and it’s the reason a lapse doesn’t have to mean a delayed closing.
If the property has never been insured under NFIP and needs a policy for the first time during a lapse, that’s the scenario that actually stalls — and it’s exactly when private flood insurance becomes worth a serious look instead of waiting on Congress.
Should You Consider Private Flood Insurance Now?
Not because NFIP is going away — it almost certainly isn’t, long-term. But a private policy sidesteps the whole question, and depending on your property, it sometimes prices better or offers higher limits than NFIP’s caps. We compare both for every flood placement we write, lapse or no lapse, because “NFIP by default” isn’t always the right call even in a normal year. See how flood insurance costs break down in the Charleston area for context on both options.
What We’re Doing About It
We’re not waiting until December 11 to figure this out. A few things worth knowing if you work with us:
- We hold both NFIP and private flood market access, so a lapse doesn’t leave us with only one option to offer you.
- We have two offices in the exact markets this affects most — Mount Pleasant and North Myrtle Beach — not a call center reading from a script.
- We’ve already been through a real lapse this year (the brief one in late January), so this isn’t theoretical for us either.
- We’ve helped save closings that were at risk over flood insurance timing before — if you’re a realtor or closing attorney with a deal that touches flood coverage between now and December 11, reach out before it becomes a problem, not after.
Frequently Asked Questions
Will my flood insurance be cancelled if NFIP lapses?
No. Policies already in force generally stay active until their expiration date. A lapse affects new and renewal policies, not coverage you already have.
I’m buying a home and the seller has NFIP flood insurance. Does a lapse affect my closing?
Usually not. The seller’s policy can typically be assigned to you by substituting the name on the policy, without a new policy being issued. Ask us to confirm this specifically for your transaction.
What if the home I’m buying has never had flood insurance?
That’s the scenario a lapse actually affects, since a brand-new NFIP policy can’t be issued during a lapse. This is exactly when a private flood policy is worth pricing out as an alternative — we can usually turn that around quickly.
How long do these lapses usually last?
It varies. The most recent one, in late January 2026, lasted only a few days. A 2025 lapse ran 43 days. There’s no way to predict which this will be, which is why we’d rather help you plan around it than guess.
Does this affect my homeowners insurance too?
No. This is specific to NFIP flood coverage. Homeowners, wind, and other coverage types are unrelated to NFIP’s authorization status.
Have a closing or renewal that touches flood insurance before December 11?
