PermitRevisionDesk: A Careful NYC Permit Change Tracker
A browser-based tool for comparing dated NYC BIS and DOB NOW permit snapshots and isolating meaningful project changes.
Field notes
The workspace processes imported permit snapshots locally in the browser rather than querying a connected public database. Its comparison model keeps BIS and DOB NOW identifiers distinct, then checks successive records for changes in status, work type, declared cost, and address. Researchers can filter results by borough, date, project, or latest status and export a limited result set. The page identifies method version 1.0.0 and warns that sources and assumptions are not independently certified.
