PermitStack holds 1,563,776 building permits from Massachusetts, read from the official permit systems of the cities and counties below. The newest permit on record here runs through October 6, 2026; 19 of the state's sources have permits from the last 45 days. Coverage is uneven because the sources are: each place's own page shows its date range and the coverage page shows whether its source is current.
Counts are permits on record for each place. Some places are covered by a county or statewide source rather than their own city feed.
