Step 3: Enter Property Address Details
Borough: Select from dropdown menu
- Manhattan = 1
- Bronx = 2
- Brooklyn = 3
- Queens = 4
- Staten Island = 5
House Number: Enter numbers only

- Submit proof: File correction documentation with DOB/HPD
- Request inspection: Schedule re-inspection to verify correction
- Pay fines: Pay ECB fines within 60 days to avoid liens
If you need help navigating the correction or filing process, you can request a free violation review from D.O.B. Guard — reviewed and quoted before you pay anything.
If You're a Buyer (Due Diligence)
- Request seller clearance: Open violations must be resolved before closing
- Negotiate price reduction: Factor correction costs ($5,000–$50,000 typical)
- Escrow funds: Hold back money to cover violation resolution
- Title search: Verify no ECB liens on property
If You're a Tenant
- File HPD complaint: If landlord ignores Class B/C hazardous violations
- Request rent abatement: Open violations may qualify for rent reduction
- Withhold rent (HP Action): File in Housing Court if hazardous conditions persist
If You're an Investor/Lender
- Factor remediation costs: Open Class 1 violations = $20,000–$100,000 to resolve
- Check for liens: ECB liens must be cleared before transfer
- Verify correction timeline: Some violations take 6-18 months to resolve
Pro Tips for Building Violation Lookups
1. Search Quarterly, Not Just at Sale
Violations can be issued anytime (311 complaints, routine inspections, permit expirations). Quarterly searches catch issues before fines escalate.
2. Check Neighboring Properties for Row Houses
For attached buildings, search adjacent properties. Violations on party walls or shared structures can affect your property.
3. Save PDFs of Clean Records
When violations are resolved, save PDF screenshots from BIS. Banks and title companies require proof of clean violation history.
4. Set Up Automated Monitoring
Manual searches are time-consuming. D.O.B. Guard monitors properties 24/7 and sends alerts the moment violations are issued.
⚡ Stop Manual Searches: Get Automatic Alerts
D.O.B. Guard monitors 11 NYC databases and texts you the moment DOB, HPD, ECB, or FDNY violations appear. Monitor unlimited properties for $15/month. Start monitoring →
Frequently Asked Questions
Can I search NYC building violations by owner name?
No. All NYC violation databases (BIS, HPD, OATH) only search by property address or BIN (Building Identification Number). Owner names are not publicly searchable.
How far back does BIS show violation history?
BIS maintains permanent records dating back to the 1980s. Even resolved violations remain in the database indefinitely.
Can I search multiple properties at once?
No. BIS requires individual searches for each property. Property owners with multiple buildings use monitoring services like D.O.B. Guard to track all properties simultaneously.
How often is BIS updated?
Daily. New violations, inspection results, and status changes appear within 24 hours of issuance.
Are all building violations public?
Yes. All DOB, HPD, and ECB violations are public records viewable by anyone. This includes buyers, lenders, tenants, and the general public.
