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.
