A compiled, cross-municipal Massachusetts building-permit panel

A compiled, cross-municipal Massachusetts building-permit panel: 78,405 permit records totalling $3,383,419,601 in declared project value, drawn from 76 separate municipal permit systems and normalized into one sortable weekly feed carrying permit holder, full property address, trade (electrical, HVAC, plumbing, gas, roofing, renovation/remodel and others), project type and declared project value. Sold as a one-time lead pack or a weekly Monday feed, with a machine-readable JSON feed and RSS alongside. A research layer sits on top and is part of the asset: cross-town record-keeping findings (a 'Friday gap' where Fridays show about half the permits of other weekdays, with at least one town filing none), a normalized ADU trend analysis that disproved an apparent rise, and a permit-sequence study establishing which trades reliably follow which and by how many weeks — including separating a genuine job sequence from one job filed twice.

Type: not stated
Format: Tabular — a clean spreadsheet plus a polished PDF report per delivery, a browser-openable sample file of around a thousand permits filterable by trade and town, an RSS feed and a JSON API endpoint; all figures recomputed from the live dataset at each site build. Public preview masks house numbers and contractor names.
Volume: 78,405 Massachusetts building-permit records from 76 municipal sources at the current build, carrying $3,383,419,601 in declared project value; an earlier indexed snapshot showed 75,270 records across 73 towns, so the panel grows town by town. The free sample alone is described as around a thousand recent permits across 45 towns. Illustrative town density: Cambridge ~2,933 recent, Boston ~1,555-1,568. Explicitly single-state and partial — Massachusetts has 351 municipalities, so coverage is roughly a fifth of the state.
Users: ~0-100 accounts (est.: self-serve low-price product — $49 one-time pack, $99/month weekly feed, free sample and a no-card newsletter — run by a single founder and only weeks old at this read; no customer roster published)

Update frequency: not stated
Growth: Active — brand new and measurably growing: records rose from 75,270 across 73 towns to 78,405 across 76 municipal sources between indexed snapshots; the homepage reports an update 17 hours before this read with a new batch every Monday; and a corrections page shows active re-verification of published claims. Coverage stands at 76 of 351 Massachusetts municipalities, so headroom is large relative to current footprint.
