Jefferson County Fair Market Rent

What these rents mean for Jefferson County

HUD's FY 2026 Fair Market Rent schedule sets the Jefferson County Idaho 1-bedroom at $1,095, with a studio at $1,034, 2-bedroom at $1,305, 3-bedroom at $1,815, and 4-bedroom at $2,189. These figures represent the 40th percentile of gross rents — meaning 60% of standard-quality rental units in this HUD area cost more. The Jefferson County FMR area applies to all ZIP codes inside the county boundary, and Idaho's housing authorities use it as the baseline when setting Section 8 Housing Choice Voucher payment standards (typically 90%–110% of FMR).

Compared to the rest of the country, a 1-bedroom here is 14% above the US average of $959 and 15% higher than the Idaho state average of $950. Year-over-year, the 1-bedroom FMR moved from $1,087 in FY 2025 to $1,095 in FY 2026 — a change of +0.7%, which tracks roughly with broader price trends.

For budgeting, the traditional 30% affordability rule says rent should not exceed 30% of gross household income. At the FY 2026 1-bedroom FMR of $1,095, that implies a household income of $43,800 per year (about $3,650/month) to stay affordable — a 2-bedroom at $1,305 pushes that threshold even higher. With a population of 31,383 and a county median household income of $82,952, the arithmetic here directly shapes which wage earners can rent without being cost-burdened. Rent-burdened households (paying more than 30% of income) and severely burdened households (above 50%) face a sharply higher risk of housing instability, and this county's numbers set the benchmark for assessing that risk.
