Non-Metro Difficult Development Areas: Effective 01-01-2026

This data layer shows U.S. Department of Housing and Urban Development (HUD) annually designated non-metropolitan Difficult Development Areas (DDAs). Non-metropolitan DDAs are areas with high construction, land, and utility costs relative to area median gross income and are based on Fair Market Rents (FMR), income limits, the 2020 census counts, and 5-year American Community Survey data. The unit of geography for non-metropolitan DDAs is the non-metropolitan county or county equivalent area. Non-metropolitan DDAs are designated annually as updated income, and FMR data are made public.
