About this result(HUD FMR/SAFMR details)

This page shows HUD Fair Market Rent data for Williamson County, IL (IL) for FY 2026. Fair Market Rent (FMR) is a HUD benchmark used to determine payment standards for programs like the Housing Choice Voucher (Section 8) program.

Values are shown for 0–4 bedroom units. In some metro areas HUD publishes Small Area FMR (SAFMR) at the ZIP-code level; otherwise the county/metropolitan-area FMR applies. This result is labeled SAFMR based on HUD's designation for the area and the available data.

Tip: use these numbers as a starting point and confirm local program rules (payment standards may differ from HUD's published FMR). If you're comparing neighborhoods, SAFMR ZIP ranges can highlight variation within the same county.
