What do Fort Worth window permits declare?
Each Fort Worth figure above is a declared permit value: what the applicant told the permit office the window replacement job was worth when applying. It is not an invoice.
The records come from City of Fort Worth (Development Services), CFW Open Data - 'CFW Development Permits Table' (ArcGIS item d2740f4d746b4bfaa03e25de0376238b; former Socrata quz7-xnsy, redirected to ArcGIS Hub).
The selection covers single-family residential building and accessory-structure permits filed from January 2023 through October 2026. Dates follow the application filing month because the dataset has no issue-date field.
Before matching, the selection left out 3 permits for legalisation, as-built work, revisions, supplements or renewals.
Of the 2,080 matched permits, 2,077 carried a declared value. The low-value check removed 45 records, leaving 2,032 permits behind the figures.

| When the household fitted them itself | a median (572 American Housing Survey data points, the United States, 2021-2023) of $750 | — |
