HPD Violations in NYC: A Complete Guide for Property Owners and Tenants

HPD Enforces the Conditions Tenants Actually Live In

While DOB focuses on structural and construction compliance, HPD — the NYC Department of Housing Preservation and Development — enforces the Housing Maintenance Code, the set of minimum standards that govern what a habitable apartment must provide. Heat in winter. Hot water year-round. Walls free of mold and lead paint hazards. Windows that lock. The conditions that directly affect whether a building is safe to live in.

HPD violations are the single largest source of housing litigation in New York City. They fuel Housing Court proceedings, rent withholding claims, and — for buildings that accumulate enough of them — designation into HPD's Alternative Enforcement Program, where the city takes over repair coordination and the owner foots the bill at above-market rates.

How HPD Classifies Violations

HPD violations carry three classifications, each with a distinct correction deadline that runs from the date the violation is served:

• Class A — Non-Hazardous: Correction required within 90 days. These are code deviations that don't immediately threaten health or safety — peeling paint in units without children under 6, broken mailboxes, missing handrail hardware. Don't let the longer deadline create complacency: Class A items pile up fast in buildings with deferred maintenance, and a stack of 90-day violations will trigger reinspection cycles that find more serious issues.
• Class B — Hazardous: Correction required within 30 days. Mold, active rodent infestation, defective window guards above the first floor, no smoke or carbon monoxide detector. Class B violations are the most common serious violations HPD issues and the most frequent basis for tenant-initiated Housing Court proceedings.
• Class C — Immediately Hazardous: Correction required within 24 hours. No heat when outside temperatures require it (below 55°F between October 1 and May 31), no hot water, gas leaks, lead paint in units where a child under 6 lives, elevator outage in a building over 6 stories. HPD follows up Class C items aggressively. A failure to correct within 24 hours can trigger an emergency repair order — the city sends a contractor, does the work, and sends the owner a bill at premium rates.

How HPD Violations Get Filed

Most HPD violations originate from one of two sources. The first — and most common — is a tenant complaint filed through 311 or HPD's online portal. When a complaint comes in, HPD schedules an inspection. If the inspector observes a code violation, it's recorded against the property's BBL and served on the owner within days. The second source is HPD's own proactive inspection program, which targets registered multiple dwellings on a scheduled cycle and buildings that have already accumulated significant violation histories.

Owners often learn about HPD violations after the fact, through hpdonline.nyc.gov or a title search. By that point, correction deadlines may already be running — or in some cases, passed.

How to Certify a Correction

1. Identify the exact condition cited. The violation notice specifies the apartment number, the condition, and the applicable code section. Repair the right thing — a correction that doesn't match the cited condition won't satisfy the violation.
2. Complete the repair with licensed trades where required. Plumbing, electrical, and gas work require licensed contractors. Boiler repairs require a licensed plumber or fuel oil equipment technician. Using unlicensed workers creates liability and may not satisfy the certification requirement.
3. Log in to HPD Online at hpdonline.nyc.gov and submit a Certification of Correction. Upload supporting documentation: dated photographs of the corrected condition, contractor invoices, and any applicable certificates or test results (e.g., lead clearance testing for Class C lead paint violations).
4. For Class C violations, expect a reinspection. HPD schedules a site visit to verify that immediately hazardous conditions have actually been corrected. Have the work complete and the unit accessible before the inspector arrives.

The Alternative Enforcement Program: What It Means to Be on the List

Each year, HPD designates approximately 200 buildings as AEP properties — the buildings across the city with the highest rates of open Class B and C violations relative to the number of units. AEP designation is not a fine; it's a full intervention. HPD assigns an AEP inspector to the building, conducts comprehensive inspections, orders repairs, and charges the owner for any work HPD coordinates directly. Buildings stay on the AEP list until violation rates drop below the threshold. The administrative and financial burden is significant, and the designation is publicly searchable — which makes it a serious obstacle in any sale or refinance.

Tenant Rights Under the Housing Maintenance Code

Tenants in buildings with open Class B or C violations have enforceable rights. Housing Court allows tenants to seek an HP proceeding compelling repairs. DHCR may grant a rent reduction order for persistent maintenance failures in rent-stabilized apartments. During heating season — October 1 through May 31 — tenants can report heat emergencies directly to HPD, triggering a 24-hour inspection and, if heat isn't restored, an emergency repair order with costs billed to the owner.
