MassPermits

MassPermits — 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-keep…

MassPermits offers (Alternative, Geospatial, Reference) — 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..

Primary stated use: contractor and trade-sub lead generation — reaching owners at permit issuance, segmented by trade and town and timed to the filing. Second-order and more interesting: the trade-sequence mapping is directly reusable as supervision for construction-workflow and next-trade-prediction models (which contractor to approach, and when); the town-level record-keeping findings make this a rare data-quality benchmark for anyone building a multi-municipal permit pipeline in Massachusetts; the normalized ADU analysis is a housing-policy measurement asset, notable for publishing a negative result; and the cross-town schema normalization is a reusable mapping for expansion into further states. Declared project value aggregated by trade and town also supports regional construction-spending nowcasting.
