Source

  • LA County unincorporated (EPIC-LA): EPIC-LA Case History, published by County of Los Angeles. Source dataset. Collected window(s): Aug 20, 2026 – Oct 14, 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). Water Heaters = the permit's type or work description matches the Curbside Signal water heater 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 Los Angeles-Long Beach-Anaheim, 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: Water heater swaps lead to gas line, venting and electrical work, and to whole-house repipes in older homes.
