Qualified census tracts by county
Sources: HUD 2027 QCT data file (qct_data_2027.xlsx), checked tract by tract against HUD's QCT2027.csv; population from the 2020 Census columns in that file. Properties: HUD's LIHTC database (LIHTCPUB, revised May 28, 2026), monitored properties by 2020 tract.
Small Area DDA ZIP codes
In metro areas HUD designates DDAs by ZIP Code Tabulation Area. A ZCTA follows ZIP code boundaries closely but not exactly, so check a specific address with the lookup.
