The U.S. Department of Housing and Urban Development has finalized the rent figures that will govern the Housing Choice Voucher program for the next year, and they take effect in less than a month. Those figures, called Fair Market Rents, set the ceiling on what a housing agency will subsidize toward a voucher holder’s rent, so a change to the underlying formula reaches into rental housing markets nationwide at once. For a family paying part of the rent out of pocket and part through a voucher, the new numbers decide how large that gap is starting October 1.
Why the Housing Choice Voucher Payment Standard Resets Every October 1
Fair Market Rents are the number HUD uses to calculate the payment standard, the maximum amount a housing agency will subsidize toward rent for a family using a Housing Choice Voucher, the program most people still call Section 8. The requirement to update that figure comes straight from the U.S. Housing Act, which HUD implements through its payment standard regulations: the agency must publish new Fair Market Rents at least once a year, effective every October 1. HUD’s fiscal year 2027 notice, filed August 31 and published September 1, 2026, sets that effective date at October 1, 2026, unless a local housing agency wins a reevaluation for its specific market.
The Fair Market Rent for an area is meant to represent the 40th percentile gross rent, shelter plus utilities, that a recent mover pays for a decent, non-luxury apartment there. It is not just a voucher number, either: HUD also uses it to set renewal rents on some expiring project-based Section 8 contracts, rent ceilings in the HOME Investment Partnerships Program and Emergency Solutions Grants, award caps for Continuum of Care homelessness grants, and flat rents in public housing, which is why one annual notice can reshape rent limits across several federal housing programs at once.

The 8.7 Percent Adjustment That Pushes Up Three- and Four-Bedroom Rent Limits
HUD calculates its core estimate around two-bedroom units, the most common size and the easiest to survey accurately, then derives every other bedroom size from it using bedroom ratios. For FY 2027, HUD adds 8.7 percent on top of the calculated three-bedroom estimate and 7.7 percent on top of the four-bedroom estimate, an adjustment the agency says is meant to help the largest families, who have the hardest time finding units that fit under a voucher’s limit. Units bigger than four bedrooms get 15 percent tacked onto the four-bedroom figure for every extra bedroom, so a five-bedroom unit’s limit runs 1.15 times the four-bedroom rate and a six-bedroom unit’s runs 1.30 times.
At the small end of the scale, a single-room-occupancy unit, a room without a private kitchen, used in HUD’s Moderate Rehabilitation SRO program, is priced at 0.75 times the local efficiency, or zero-bedroom, rate. HUD also boxes in how far any bedroom size can drift from the two-bedroom number: efficiencies must land between 70 and 88 percent of it and one-bedrooms between 76 and 92 percent, before the three- and four-bedroom boosts are layered on. None of this is a judgment call made market by market, it is the same formula applied everywhere the notice covers.
HUD Built the FY 2027 Numbers From 2024 Rent Data, Then Trended Them Forward
The base rents behind the FY 2027 figures come from the Census Bureau’s five-year American Community Survey covering 2020 through 2024, adjusted using a recent-mover factor that captures what people who moved into their unit within the past year actually paid in 2024. HUD then inflates that 2024 figure using a blended measure of rent growth, roughly 55 percent from private rent trackers such as Apartment List, CoStar, Zillow and RealPage, and roughly 45 percent from the Consumer Price Index’s rent-of-primary-residence series, to bring the estimate up to 2025, then trends it forward again with local or regional forecasting models to project it out to FY 2027.
One piece of the formula changed this year: HUD switched how it measures utility cost inflation after the Bureau of Labor Statistics discontinued the local housing fuels and utilities index HUD used to rely on. The replacement blends state-level U.S. Energy Information Administration data on electricity, natural gas and fuel oil with national water, sewer and trash cost data. HUD publishes the full area-by-area calculations, including the underlying data, on its Fair Market Rents documentation page. Because the newest survey data behind any FMR is already more than a year old by the time it takes effect, the published number can lag a fast-moving local rental market even when HUD’s math is followed exactly.
A 10 Percent Floor Keeps Fair Market Rents From Falling Too Fast in One Year
HUD’s own regulations cap how much a Fair Market Rent can drop in a single year: no area’s FMR can fall below 90 percent of what it was the year before, regardless of what the underlying rent data would otherwise produce. If the formula generates a steeper cut, HUD simply sets the new number at that 90 percent floor instead. A separate, nationwide floor works the same way for the smallest markets: for FY 2027, the national non-metropolitan two-bedroom minimum is $1,014, and no non-metro area’s two-bedroom Fair Market Rent can be set below the lower of its state’s or the nation’s non-metro median.
In large metro areas, a different guardrail runs the other direction. Where HUD requires Small Area Fair Market Rents, ZIP-code-level numbers rather than one figure for an entire metro area, mandatory in dozens of metro areas including 41 added under a 2023 HUD expansion, no single ZIP code’s two-bedroom number can exceed 150 percent of the metro-wide Fair Market Rent, so one expensive neighborhood cannot push a voucher payment far past what the rest of the metro area supports.
Renters and Housing Agencies Have Until October 1 to Challenge Their Area’s Numbers
HUD is accepting public comments on the FY 2027 methodology, and separately, on requests to reevaluate the Fair Market Rent set for a specific area, through the same October 1, 2026 deadline the new numbers take effect. Comments and reevaluation requests go through the public docket on Regulations.gov. A reevaluation request has to come from the local housing agency, or, in areas with more than one, agencies representing at least half the voucher holders there, and it has to be backed by the agency’s own rent survey data, not just a complaint that the number feels low.
Agencies that file a valid request can keep using the FY 2026 Fair Market Rent while the reevaluation is pending, but they have to deliver their supporting survey data to HUD by January 8, 2027, and HUD expects to post any revised figures next April. For a voucher holder searching for an apartment this fall, none of that changes what governs the search today: the number that took effect October 1 is the one landlords and housing agencies work from until a reevaluation, if any, actually comes through.
