How to Read an HPD Violation Report: Real Examples for NYC Renters

What Is HPD and Where Does This Data Come From?

The NYC Department of Housing Preservation and Development (HPD) enforces the city's Housing Maintenance Code. When a tenant files a 311 complaint or HPD conducts a proactive inspection, inspectors visit buildings and issue violations for any conditions that fail to meet code. These violations become part of the public record.

RenterBuzz pulls open violation data directly from NYC Open Data and displays it on every building page — organized by class, with dates and descriptions. You can see this data before you ever speak to a landlord.

The Three Classes of Violations — With Real Examples

Class C — Immediately Hazardous (Fix within 24 hours)

Class C violations represent the most serious conditions — ones that pose an immediate risk to health or safety and require correction within 24 hours. These are the violations that matter most when researching a building.

Real Class C examples you might see on a building page:

• "PROVIDE ADEQUATE HEAT" — The apartment temperature fell below the legal minimum during heat season. This is one of the most common Class C violations in NYC.
• "REMOVE OR REPAIR THE FIRE ESCAPE" — A fire escape is damaged, blocked, or non-functional. This is a life-safety issue.
• "ABATE THE NUISANCE CONSISTING OF MICE" — Active rodent infestation documented by an inspector.
• "PROVIDE HOT WATER" — Hot water below the legal 120°F minimum at the tap.
• "REMOVE LEAD PAINT HAZARD" — Lead-based paint hazard in an apartment where a child under 6 lives.
• "REPAIR DEFECTIVE ELECTRICAL WIRING" — Exposed, damaged, or improperly installed electrical wiring.

What it means for you: A building with multiple open Class C violations — especially heat violations in winter or rodent violations year-round — is a significant red flag. The landlord has been formally notified of dangerous conditions and has not corrected them within the required timeframe. On RenterBuzz, these show in red.

Class B — Hazardous (Fix within 30 days)

Class B violations are hazardous conditions that require correction within 30 days. They are serious but not immediately life-threatening.

Real Class B examples:

• "REPAIR THE BROKEN OR DEFECTIVE PLASTERED SURFACES IN THE BATHROOM" — Water-damaged walls that may indicate moisture problems or mold behind the surface.
• "REMOVE ALL OBSTRUCTIONS AND/OR DEFECTS IN THE PUBLIC HALL" — Blocked or damaged hallways affecting building egress.
• "REPAIR THE ELEVATOR" — A non-functional or unreliable elevator in a building that has one.
• "REPAIR THE SMOKE DETECTOR" — Missing or non-functional smoke detector (in some contexts this is Class C).
• "STOP THE WATER LEAK IN THE CEILING" — Active water intrusion causing damage and potential mold.

What it means for you: A handful of Class B violations in a large building is not unusual. Dozens of unresolved Class B violations — especially water-related ones — suggests a landlord who defers maintenance and ignores problems. Cross-reference with the 311 complaint panel on RenterBuzz to see if tenants are also reporting these issues through the city.

Class A — Non-Hazardous (Fix within 90 days)

Class A violations are below the maintenance standard but do not create immediate health or safety risk. They must be corrected within 90 days.

Real Class A examples:

• "PAINT WITH 2 COATS THE NORTH WALL OF THE KITCHEN" — Peeling or faded paint in a specific location.
• "REPAIR THE BROKEN FLOOR TILES IN THE BATHROOM" — Minor floor damage.
• "REPAIR THE DOOR KNOB" — A loose or broken door fixture.
• "PROVIDE WINDOW GUARDS" — Missing required window guards in an apartment with young children.
• "SEAL AND MAINTAIN IN A WORKMANLIKE MANNER" — Gaps or openings that could allow pest entry.

What it means for you: A few Class A violations in a building are common and generally not concerning. Dozens of unresolved Class A violations over several years suggest a landlord who ignores even minor maintenance — which often predicts worse neglect when bigger issues arise.

How to Analyze Violation Data Like a Pro

Look at the Date, Not Just the Count

A violation from 4 years ago may have been resolved even if it shows as "open" in some datasets. RenterBuzz shows the violation issue date — pay more attention to violations from the last 12-18 months.

Scale to Building Size

10 violations in a 200-unit building is very different from 10 violations in a 6-unit building. Think in terms of violations per unit, not raw counts.

Look for Patterns

Three heat violations filed every winter for three consecutive years is a chronic problem — not bad luck. Repeated violations of the same type tell you something systematic about how the building is managed.

Cross-Reference with 311 Complaints

RenterBuzz shows both HPD violations and 311 complaint history on every building page. A building with many heat violations AND hundreds of 311 heat complaints is doubly confirmed — this is a real and ongoing problem.

A Real-World Scenario

Imagine you are looking at two buildings in the same neighborhood at the same price:

• Building A: 3 Class A violations (paint, minor repairs), 0 Class B, 0 Class C. 12 heat complaints over 2 years, all filed in a single week two winters ago. No recent violations.
• Building B: 8 Class C violations (heat, mice, water leak), 15 Class B violations (water damage, broken elevator), 22 Class A violations. 340 heat complaints over 2 years — a steady flow every winter.

Building A had a rough week two years ago and the landlord fixed it. Building B is a pattern of systemic neglect. This is exactly the kind of insight that RenterBuzz puts at your fingertips before you ever sign a lease.
