The HUD Section 8 program is the U.S. government's largest housing assistance program. In order to help low-income families find quality housing, a local Public Housing Authority (PHA), funded by HUD, will pay a private landlord part or all of the unit’s rent. The largest program within Section 8 is called the Housing Choice Voucher Program, which allows a family to choose their own unit from within the pool of Section 8 properties in their area.
Fair Market Rents (FMRs) are a statistic developed by HUD in order to determine payments for various housing assistance programs, most notably, the Section 8 Housing Choice Voucher Program. FMRs differ by local area, and are updated on an annual basis. You can determine current and historical FMRs for your area by visiting HUD’s FMR Dataset and Search Tool.
