Why this data is real
We classify permits into real segments — and label what we don't know.
Classified, not scraped
We read each permit's work-type, scope, and occupancy fields to place it in a real segment — so “commercial HVAC in Boston” means real HVAC work, not a keyword match.
Parcel-joined + enriched
Every permit is joined to its tax lot and geocoded, with roof & HVAC sized — you see the building, not just the address.
— and we flag what we don't know
Coverage is labeled, missing fields show —, and where there are too few reliable filings to stand behind a value we publish —, never a fabricated number.
