Metric: Residential = the source marks the permit's use as residential (permits with commercial or unknown use are not counted). Windows & Doors = the permit's type or work description matches the Curbside Signal windows & doors rules. Counts exclude void or cancelled permits. Dates are the jurisdiction's permit issue date. Records are deduplicated on source and permit number. How we count. Part of the Washington-Arlington-Alexandria, DC-VA-MD-WV metro: every trade × city page there.
The honest limit. A permit usually means the job is already sold. We say that up front. The value is what happens around it:
- Neighbor marketing around active jobs: same-age houses on the same street.
- Cross-trade follow-on demand: new roof → solar, gutters, insulation; remodel → HVAC, electrical, landscaping, pool; new build → pest, security, landscaping.
- Competitor intelligence: which contractors pull permits where (where the jurisdiction publishes it), and who to recruit as subs.
- Early-stage projects for commercial trades and GC subs.
Follow-on: Remodels, additions and siding jobs are the biggest upstream drivers of window and door work.
