Enter any NYC address into RegWatch or search DOB NOW / BIS directly. RegWatch combines both systems.
Check if permits are pre-filing, approved, issued, or signed off. Open or expired permits may need attention.
Permits can have associated violations for non-compliance. RegWatch cross-references these automatically.
DOB is transitioning from BIS to DOB NOW. Some records are in one system, some in the other. RegWatch aggregates both to ensure complete coverage.
