Source

  • Boston: Permit records on data.boston.gov (dataset 6ddcd912-32a0-43df-9908-63574f8c7e77), published by Boston. Source dataset. Collected window(s): Aug 23, 2026 – Oct 17, 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). Insulation = the permit's type or work description matches the Curbside Signal insulation 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 Boston-Cambridge-Newton, MA-NH 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: Re-roofs, re-sides and heat-pump installs are the main upstream signals for insulation.
