Two of the country’s largest rental markets got more room to charge under a federal rent ceiling this fall, while five others got less. Los Angeles and Chicago are among the metro areas where HUD’s newly published Fair Market Rents rose sharply for fiscal year 2027, effective October 1, 2026. Phoenix, Dallas, Houston, San Diego and Atlanta are moving the opposite direction, with lower ceilings taking effect the same day.
Reading a Rent Ceiling as a Map, Not a Single Number
Fair Market Rent is HUD’s area-by-area estimate of what a recent mover would pay for a modest two-bedroom unit, and it feeds directly into how much a Housing Choice Voucher is worth in that specific market. Because it is calculated separately for each of 2,606 areas rather than as one national figure, a year that looks flat or even up in the aggregate can hide sharp movement in both directions underneath. That is what happened heading into FY 2027: nationally, the population-weighted change came in at a modest 2.4 percent increase, an average of metro areas moving in opposite directions, not a description of what happened anywhere in particular.
Among the 25 largest FMR areas, Padmission’s comparison of HUD’s FY 2026 and FY 2027 files found Los Angeles and Chicago moving up sharply, while Dallas, Houston, Phoenix, San Diego and Atlanta all came down. Those metro-level groupings are Padmission’s own compilation of HUD’s published area files; HUD’s notice lists the resulting figures for each area but does not rank or group them by metro the way Padmission’s analysis does.

Arizona’s Decline Is Almost Entirely a Phoenix Story
Statewide, Arizona posted the steepest population-weighted decline of any state in the country, and Padmission’s data attribute nearly all of that drop to a single metro area: Phoenix is falling hard enough to drag the whole state average down, while Tucson’s Fair Market Rent is essentially flat year over year. That split matters for how the decline should be read. This is not evidence that Arizona rents broadly softened, but that one large, fast-growing metro area’s underlying rent data cooled enough to pull its Fair Market Rent down while a smaller Arizona metro barely moved at all.
The same unevenness shows up around the other four falling metros. Dallas, Houston, San Diego and Atlanta are each calculated independently, using each area’s own Census rent data, recent-mover trends and inflation factors; there is no single “Sun Belt effect” written into HUD’s methodology that moves those areas together. That they moved in the same direction this year reflects overlapping local rental-market conditions, not a rule that treats them as a bloc. Los Angeles and Chicago sit on the opposite side of that same independent process: each area’s own base rents and recent-mover data simply came in strong enough to clear HUD’s inflation and trend adjustments and land above last year’s published figure, with nothing in the methodology that ties their increase to any other area’s decline.
The Regulatory Floor Behind the Steepest Drops
Wherever a metro’s underlying rent calculation would have produced a decline steeper than 10 percent, HUD’s own rule limits how far the published number is allowed to fall. Under HUD’s Federal Register notice, a current year’s Fair Market Rent cannot be set below 90 percent of the prior year’s figure for the same bedroom size, regardless of what the raw data shows. That floor does not change which direction a metro area is moving, and it is not the reason Phoenix, Dallas, Houston, San Diego or Atlanta appear in the falling column this year; the underlying calculations, not the floor, are what pulled each of them down.
Where the floor does matter is at the edges: in an area whose calculated FMR would have fallen further than 10 percent, a local housing agency can request permission from HUD to use the lower, “unfloored” figure instead of the published one when it sets its own payment standard, a detail spelled out in the same notice under the rule at 24 CFR 888.113.
How the Divergence Changes a Voucher Search
For a family holding a Housing Choice Voucher, the practical effect of this divergence depends entirely on where they are searching. A household with a voucher in the Los Angeles or Chicago area gets a higher payment standard to work with starting October 1, which can open up units that were previously out of reach. A household searching in Phoenix, Dallas, Houston, San Diego or Atlanta faces a lower ceiling on the same date, which can narrow the pool of units a landlord will accept a voucher for, particularly in neighborhoods where market rent already sits close to or above the old Fair Market Rent.
The effect is not limited to new voucher applicants, either. Housing agencies in Phoenix, Dallas, Houston, San Diego and Atlanta also use the Fair Market Rent to calculate the Renewal Funding Inflation Factor that determines their own federal voucher funding for the coming year, so a falling FMR can tighten an agency’s budget at the same time it tightens what a household can offer a landlord. In Los Angeles and Chicago, the same mechanism works in the opposite direction, giving both the household and the local housing agency more room than they had a year ago.
None of these figures are proposals. All of them are the published, effective FY 2027 numbers unless a specific area’s public housing agency requests and receives a formal reevaluation before HUD’s October 1 comment window closes.
Padmission’s full area-by-area table, compiled directly from HUD’s FY 2026 and FY 2027 FMR files on September 1, 2026, remains the most granular public breakdown of which of the 25 largest metro areas moved up and which moved down under the new rent ceilings.
