Many NYC landlords confuse HPD and DOB violations. They're issued by different agencies, follow different rules, and require completely different responses.
Walk into any NYC landlord forum and you'll see it constantly — property owners confused about whether they have an HPD or DOB violation, what it means, and who to call. These are two completely different agencies with different enforcement powers, different penalty structures, and different resolution processes. Confusing them — or treating them the same — is an expensive mistake.
The Quick Answer
| HPD | DOB / ECB | |
|---|---|---|
| Full name | Housing Preservation & Development | Department of Buildings |
| Focus | Tenant living conditions | Building code & construction |
| Typical violations | Heat, pests, lead paint, mold | No permits, unsafe construction, facade |
| Penalty system | Civil penalties, Housing Court | ECB fines + OATH hearings |
| Resolution | Certificate of Correction | CofC + OATH hearing |
| Max daily fine | $150/day (Class C) | $25,000+ (Imm. Hazardous) |
| Who can be cited | Building owner/landlord | Owner, contractor, or both |
HPD: The Tenant Protection Agency
The NYC Department of Housing Preservation and Development is the city's landlord cop. Its job is to enforce the Housing Maintenance Code — the rules that define the minimum living conditions NYC tenants are entitled to. When a tenant calls 311 to complain about heat, hot water, roaches, mold, or a broken lock, HPD sends an inspector.
HPD violations are classified A, B, or C. Class C violations (immediately hazardous) must be corrected within 24 hours. Class B (hazardous) within 30 days. Class A (non-hazardous) within 90 days. Penalties accrue daily after the deadline, and HPD can escalate to Housing Court where judges have broad powers to compel compliance.
One key feature of HPD violations: they include the building's registered owner information from the HPD registration database. This makes HPD violation data especially useful for identifying who owns a building and how to contact them.
DOB: The Building Code Enforcer
The NYC Department of Buildings is concerned with whether buildings are structurally sound, properly permitted, and built according to code. DOB inspectors come to buildings for permit inspections, respond to construction complaints, and conduct proactive safety programs like FISP (facade inspections for taller buildings).
When DOB cites a violation, it goes to the Environmental Control Board (ECB) — a quasi-judicial body that handles hearings and fines. Every ECB violation triggers a mandatory OATH hearing. The fines are significantly higher than HPD penalties and the process is more formal.
Unlike HPD violations, DOB ECB violations can be issued to contractors, not just property owners. If you hired a contractor who did work without a proper permit, you may receive a violation even if you didn't know the permit was missing.
Key Differences in the Resolution Process
HPD violations are resolved by correcting the condition and filing a Certification of Correction online. For most violations, you self-certify — no hearing required. HPD may schedule a reinspection to verify, especially for Class C violations.
DOB ECB violations require attending an OATH hearing — or having a representative attend on your behalf. Even if you've fully corrected the violation, you must still appear at the hearing. Failing to appear results in a default judgment, typically the maximum penalty. After the hearing, you file a CofC with the DOB.
Can You Have Both at the Same Time?
Absolutely — and it's more common than you might think. A building undergoing renovation might have DOB ECB violations for construction without a permit while simultaneously having HPD violations for conditions in occupied units. These are completely separate tracks that must be handled independently.
This is why using a tool that searches both HPD and DOB ECB violations simultaneously is so valuable. You get the full picture of a property's compliance status in one place rather than toggling between HPD Online, DOB BIS, and other city portals.
Which Is More Serious?
Both can be extremely serious — but in different ways. A Class C HPD violation can result in Housing Court proceedings that strip you of control of your building. An immediately hazardous DOB ECB violation can result in a Stop Work Order, a vacate order forcing tenants to leave, and fines exceeding $25,000.
The smart approach: treat both with equal urgency. Search for open violations regularly, correct them immediately, certify corrections promptly, and keep documentation. The landlords who get into serious trouble are almost always the ones who were caught off guard by violations they didn't know existed.
