• county: County name.
• fmr_area: HUD's name for the fair market rent area the county belongs to. Counties with the same area share the same rents.
• efficiency: Monthly fair market rent, rent plus utilities, for an efficiency (no separate bedroom), in dollars.
• one_br: Monthly fair market rent for a one-bedroom home, in dollars.
• two_br: Monthly fair market rent for a two-bedroom home, in dollars.
• three_br: Monthly fair market rent for a three-bedroom home, in dollars.
• four_br: Monthly fair market rent for a four-bedroom home, in dollars.

Caveats

• A fair market rent is HUD's estimate of the gross rent, meaning rent plus tenant-paid utilities, of a modest rental home in the area. HUD sets it near the 40th percentile of what recent movers pay, so about 40 percent of such rentals cost less. It is a ceiling for housing subsidies, not the average rent and not what any listing asks.
• Each figure is for a fiscal year of the federal government. HUD's fiscal year 2027 rents take effect October 1, 2026, and are computed from earlier surveys, so they trail the market.
• Counties that HUD groups into one fair market rent area share a single value. Boise City's area covers four counties and Idaho Falls's covers two; the area name is given with each county's current rents.
• HUD has redrawn fair market rent areas over time, so a jump between years can come from a county joining or leaving an area rather than from rents. HUD's Boise City area is its own definition and is not the Census Bureau's Boise City metropolitan area.
• Through fiscal year 1994 HUD set rents at the 45th percentile; from fiscal year 1995 it uses the 40th percentile, so rents before and after are not strictly comparable. HUD's file has no figures for fiscal year 1984.
• Some years move sharply because of how HUD updates its estimates: Ada County's two-bedroom rent rose 32 percent from fiscal year 2024 to 2025, then fell in each of the next two years.
