Source
- Riverside County unincorporated (TLMA): TLMA Permits (Open Data), published by County of Riverside TLMA. Source dataset. Collected window(s): Aug 21, 2026 – Oct 15, 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). Plumbing = the permit's type or work description matches the Curbside Signal plumbing 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 Riverside-San Bernardino-Ontario, CA 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 drive plumbing, electrical and HVAC together, so Pro Signals customers often partner across trades on the same addresses.
