DOB BIS vs. DOB NOW
Definition: NYC uses two systems. BIS is the legacy database for historical records and some enforcement. DOB NOW is the current portal for filing, permits, inspections, and most post-2018 jobs. Always check both.
| Topic | DOB BIS | DOB NOW |
|---|---|---|
| Role | Legacy record system | Active filing/permit portal |
| Coverage | Older jobs, complaints, violations, permits, inspections | Most new jobs, permits, inspections, occupancy updates |
| What you’ll find | Property Profile, Jobs/Filings, Complaints, Violations, Permits | Job filings (Alt-1/Alt-2, PL/EW/SP/MH), Work Permits, Inspections, Sign-offs |
| When to use | Research history before bidding, check old violations/complaints, see legacy permits | Track current filing status, pull/verify permits, book inspections, confirm sign-offs |
How to look up an address
- Search the property in BIS and review: Property Profile → Jobs/Filings, Complaints, Violations, Permits.
- Search the same address in DOB NOW and review: Filings, Work Permits, Inspections, Sign-offs.
- Match by BIN/BBL to confirm you’re on the same property.
Before you renovate, confirm
- No open ECB/OATH or DOB violations that block permits
- Any required filing type (Alt-2, Alt-1, LAA for plumbing, etc.)
- Final sign-offs for prior work; close open permits
Notes: Landmarks (LPC) and condo/co-op boards can add approvals even when DOB shows “OK.” Some enforcement items still live only in BIS. Cross-check both systems every time.
