Guides and next steps

Frequently asked questions

How do I look up NYC building violations by address?

Enter house number and street name (ZIP optional). We normalize the street and query the official HPD violations dataset. Results list status, class, and description.

What’s the difference between HPD housing violations and DOB/ECB (OATH) violations?

HPD covers Housing Maintenance Code issues inside residential buildings. DOB and ECB/OATH relate to construction, safety, and code enforcement across all property types. A building can have both.

What is an ECB (OATH) violation notice?

It’s a summons issued for code infractions that go to a hearing at OATH. Some require correction and proof; others involve fines. See our guide: What is an ECB violation?

How current is the data and which dataset does this tool use?

We use NYC Open Data: HPD Housing Maintenance Code Violations (wvxf-dwi5). Updates depend on the city’s publishing cadence; recent entries may lag official systems.

Can I get alerts when new violations appear for my address?

Yes—subscribe after a lookup to receive email updates when new entries are published for your address.

How do I fix or dismiss a violation (HPD vs. DOB/ECB)?

HPD violations usually require correction and certification; DOB/ECB may require hearings and proof of correction. For steps, see our ECB/OATH guide.

Do 311 complaints show up before violations? How do they relate?

Often. Complaints can precede inspections that generate violations. Learn how to check: 311 and DOB complaints.

Why can’t I find my address? (street formatting, borough, ZIP tips)

Try abbreviations in caps (e.g., “AVENUE”, “STREET”), include house number only, and confirm borough/ZIP. Some entries appear under alternate street formats.
