Federal flood insurance authority expires September 30, and South Carolina has more than 5,500 condominium association policies riding on it
2026-09-19 · South Carolina · Regulation
Eleven days from now, the National Flood Insurance Program's authority to write or renew a policy expires by operation of statute. The text of 42 U.S.C. § 4026 is one sentence: "No new contract for flood insurance under this chapter shall be entered into after September 30, 2026."1
That date was set on February 3, 2026 by Pub. L. 119-75, which substituted "September 30, 2026" for the prior expiry as part of the package that ended the shutdown and cured the January 2026 lapse.
The South Carolina exposure, counted
FEMA publishes its policy records through the OpenFEMA NFIP dataset, last refreshed September 9, 2026. Filtered to South Carolina properties whose policy term had not ended as of September 19, 2026:
- 132,185 active South Carolina policy records.
- 5,466 coded "A" — condominium association — plus 86 coded "L," low-rise residential condominium building association policies. That is more than 5,500 South Carolina condominium association or master flood policies.
- 3,536 coded "U," individual condominium units insured by a unit owner or by an association.
One caution on that figure, which FEMA states in its own data dictionary: a residential condominium building association policy is stored as a single record but insures every unit in the building. The number of South Carolina condominium units standing behind those 5,552 records is considerably larger.2
What a lapse does, and does not do
FEMA's position is published and specific. During a lapse the programme "cannot issue new or renewal flood insurance policies until the program is reauthorized." Claims are treated differently: FEMA states it "would still have authority to ensure the payment of valid claims with available funds," and notes that it and Congress "have never failed to honor the flood insurance contracts in place with NFIP policyholders."3
Why renewal, not claims, is the association problem
An existing policy continues to its term end and claims under it continue to be paid. The break is at renewal. A residential condominium building association policy that comes up for renewal during a lapse cannot be renewed while the lapse runs.
The consequence runs through the mortgage. A lender will not close on a unit in a Special Flood Hazard Area without flood coverage in force, and in a condominium the building's master flood policy is what satisfies that requirement for the structure. So a lapse does not merely inconvenience the association — it stops unit sales in the building, for every owner, regardless of that owner's own circumstances.
The National Association of Realtors estimates a lapse disrupts roughly 1,300 property sales a day nationally, about 40,000 closings a month. In South Carolina the concentration is coastal: Horry, Charleston, Beaufort and Georgetown Counties hold the bulk of the state's flood-zone condominium stock.
The history says short extension, not collapse
This is not a novel cliff. The programme has run on short-term reauthorisations — 35 of them since the end of fiscal 2017 — with the last long-term reauthorisation being the Biggert-Waters Act of 2012. The February 2026 extension itself came after a lapse that began January 30, 2026 and was cured retroactively.
A reform vehicle exists: the NFIP Reauthorization and Reform Act of 2025, H.R. 5484 in the 119th Congress, which would cap annual premium increases and add affordability provisions. A further extension riding on fiscal 2027 appropriations is the ordinary outcome. But the statutory text is what it is until Congress changes it, and the date is September 30.
What makes this year's date different in South Carolina
The flood deadline falls in the same window as two other financing constraints on the same buildings.
Fannie Mae and Freddie Mac retired Limited and Streamlined project review for loan applications dated on or after August 3, 2026, pushing established projects into Full Review — which examines budgets, reserves, deferred maintenance, insurance and litigation. And the reserve-funding minimum rises from 10% to 15% of budgeted assessment income for applications dated on or after January 4, 2027.
A coastal South Carolina regime can therefore face a project review it does not pass and a master flood policy it cannot renew within the same quarter. Both problems present the same way from the outside: units that will not close.
What is knowable and what is not
Knowable: the statutory expiry date, the policy counts, and the fact that renewals stop during a lapse. Not knowable from any source: whether Congress extends before September 30, and on what terms. Anyone stating a probability is guessing.
The insurance obligations a South Carolina association carries come from its declaration and from lender requirements rather than from state statute, which is why a federal programme lapse reaches South Carolina associations directly and without any state-law buffer. South Carolina imposes no statutory flood-coverage requirement of its own.
