What a board can check this month

The renewal date on the master flood policy, against September 30. That is a five-minute check with a consequence measured in weeks.

A pending vehicle exists — H.R. 5577, the NFIP Extension Act of 2026 — and the legislation that ended the October 2025 lapse reauthorized the programme retroactively. Neither fact helps a closing scheduled for October 8.

Note also what happened during the last lapse: the Congressional Research Service records that “some lenders suspended the requirement for homebuyers to purchase flood insurance.” That is a lender-by-lender accommodation, not a rule, and it is not something a board or a seller can count on.

The rate trap that comes with raising coverage

NFIP premium increases are capped at 18 percent a year under 42 U.S.C. §4015(e)(1) — “the chargeable risk premium rate for flood insurance under this chapter for any property may not be increased by more than 18 percent each year” — and FEMA's own Risk Rating 2.0 materials describe the glide path: “all policies formerly eligible for grandfathering will transition to their new full-risk premium. Increases will be gradual and within the 18% annual cap imposed by Congress.”³

But the statute removes the cap in specified cases, including where the policyholder “has — (I) decreased the amount of the deductible; or (II) increased the amount of coverage.”

An Oregon association raising its building policy limit to satisfy a lender's 100-percent-replacement-cost requirement has increased the amount of coverage. On the face of §4015(e)(1)(C)(ii), that association can lose its glide-path protection and move to the full-risk rate in one renewal. A board doing coverage-sufficiency work and flood-policy work in the same year should understand the interaction before it acts, not after the renewal notice arrives.

Oregon's other flood problem, which no other state has in this form

Since 2016, FEMA's implementation of the NFIP in Oregon has been constrained by a National Marine Fisheries Service biological opinion concluding that continuing as-is would jeopardise 16 anadromous fish species and the Southern Resident Killer Whale and adversely modify critical habitat.

Every Oregon NFIP community had to adopt one of three Pre-Implementation Compliance Measures by December 1, 2024, or default to a permit-by-permit approach; communities choosing the model ordinance had to adopt it by August 29, 2025. The three options are: prohibit all new development in the floodplain; incorporate the ESA performance standards into local floodplain ordinances through a model ordinance; or require permit applications to include a Floodplain Habitat Assessment demonstrating no net loss of flood storage, water quality and vegetation.⁴

Which one applies varies by city and county. For an Oregon association with common property in a mapped floodplain, that choice determines whether a capital project is routine or requires a consultant. Rebuilding a clubhouse, replacing a parking area, regrading, or removing riparian vegetation can now require a habitat assessment.

The city or county floodplain administrator knows which of the three its jurisdiction adopted, and that answer feeds the reserve study assumptions. Our Oregon reserve studies page covers how capital planning is supposed to work.

What to watch next

September 30, and whether Congress acts before it. Thirty-five short-term reauthorisations since 2017 is a pattern, and two lapses in eleven months is a different pattern. A board with an October renewal should not assume the first one holds.
