Federal regulations do not require a housing authority to change anything the moment a new rent ceiling takes effect. HUD’s fiscal year 2027 Fair Market Rents become official on October 1, 2026, but the agencies that actually run local voucher programs have a separate, longer clock for putting those numbers to work. Under HUD’s own rule, they get up to three months past that date to adjust the figure that sets a voucher’s real dollar value.
The Three-Month Window Written Into Federal Rule
The timeline comes straight from federal regulation, not agency discretion. Every housing authority running the Housing Choice Voucher program must maintain a “payment standard schedule,” the local dollar amounts tied to each unit size that actually cap a voucher’s subsidy. 24 CFR 982.503(c)(3) states that a housing authority “must revise its payment standard amounts and schedule no later than 3 months following the effective date of the published FMR if revisions are necessary.” For the FY2027 FMRs, that effective date is October 1, 2026, so agencies have until roughly the end of the year to bring their own numbers into line, not a single day.
That window exists because a payment standard schedule is a local administrative document, built by each housing authority’s own staff, board, or contracted administrator, not something HUD updates for them. A single housing authority can be responsible for several separate FMR areas at once, and within each one it may also carve out its own smaller “payment standard areas,” no smaller than a census tract block group, each with its own dollar figure by unit size. Recalculating every one of those figures, then formally adopting the revised schedule, takes real staff time, which is exactly what the three-month buffer is meant to cover.

What the “Basic Range” Actually Means
The three-month clock only starts ticking “if revisions are necessary.” A housing authority does not have to touch its schedule at all if its current payment standards already sit inside what the regulation calls the basic range: anywhere from 90 percent up to 110 percent of the newly published FMR for that unit size. Agencies can set different percentages for different bedroom counts within that band without asking HUD for approval. So a housing authority whose current numbers already fall inside the new basic range can simply leave them alone, while one whose numbers now sit outside that band, because the FMR moved sharply in either direction, has until the three-month deadline to fix it. Some agencies operate outside the basic range entirely: those that can show low voucher success rates or high rent burden among assisted families may get HUD’s blessing to set “exception” payment standards as high as 120 percent of the FMR, and in a few cases higher still, precisely because the ordinary 90-to-110-percent band was not covering rents families could actually find.
A Second Clock Running at the Same Time
A separate, shorter clock is running in parallel, and it can change which FMR a housing authority is even working from. The FY2027 FMR notice opened a 30-day window, closing October 1, 2026, for a housing authority, or a group of agencies representing at least half the voucher holders sharing an FMR area, to formally request a reevaluation of their area’s new figure. An agency that files a valid request can choose to keep using the FY2026 FMR while the reevaluation is pending, rather than immediately switching to the FY2027 number the three-month rule would otherwise apply to. Requesting a reevaluation is not automatic relief from the three-month clock everywhere else in the country; it only pauses the switch to FY2027 numbers in the specific FMR area named in that request.
Areas That Could Still Be Using Last Year’s Numbers Into 2027
For agencies that go that route, the timeline stretches well past three months. The Federal Register notice requires reevaluation data to reach HUD no later than January 8, 2027, after which HUD plans to post any revised figures, along with a new Federal Register notice responding to comments, in April 2027. HUD has also said it will publish, at its public FMR dataset page, a list of areas that requested reevaluations but never delivered supporting data; those areas simply revert to the FY2027 FMR at that point. In effect, a jurisdiction under an active reevaluation request can be running on FY2026 numbers for months after every other agency in the country has already moved to FY2027, and its own three-month payment standard clock does not start until its FMR question is finally settled.
What the Timeline Means While You Wait
For a renter or landlord watching this play out locally, the practical lesson is that “the FMR changed October 1” and “my housing authority’s voucher amount changed” are two different events, sometimes separated by weeks and occasionally by a full reevaluation cycle. A housing authority’s website or administrative plan, not the federal notice itself, is the place to confirm which payment standard schedule, and which fiscal year’s numbers, currently apply in a specific jurisdiction, since two neighboring counties can legally be running two different years’ figures at the same time.
