Source
- Seattle (building): Permit records on cos-data.seattle.gov (dataset 76t5-zqzr), published by Seattle (building). Source dataset. Collected window(s): Aug 22, 2026 – Oct 16, 2026. Last pulled Oct 18, 2026.
Metric: Residential = the source marks the permit's use as residential (permits with commercial or unknown use are not counted). Foundation Repair = the permit's type or work description matches the Curbside Signal foundation repair 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 Seattle-Tacoma-Bellevue, WA 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: Foundation work leads to drainage, landscaping and interior repair.
