Source
- Lake County IN (assessor permit tracking, all municipalities): Permit records on lcsogis.lakecountyin.org, published by Lake County IN (assessor permit tracking, all municipalities). Source dataset. Collected window(s): Aug 29, 2026 – Oct 23, 2026. Last pulled Oct 27, 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 Chicago-Naperville-Elgin, IL-IN 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.
- Contractor activity: 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 Whole City customers often partner across trades on the same addresses.
