The 25 Most Common HPD Housing Violations in NYC

The single most common HPD violation in 2025 was not a broken pipe or a pest. It was paperwork: 73,381 violations for owners who did not file the annual bedbug report. After that come missing building registrations, broken self-closing apartment doors, and a long tail of repairs to plaster, fixtures, roaches, mice, smoke detectors and leaks. The 10 most common violation types alone account for 54% of the 917,928 violations from 2025 inspections.

How we counted

Every HPD violation carries an order number, a code for the type of condition and the section of law it cites. We counted 2025 violations by order number and hazard class, because the same order number can be issued in more than one class. Order 501 (repair or replace a broken or defective item), for example, appears as both Class B and Class C. Each order number-and-class pair is one row below. The labels are our plain-English summaries of HPD's own violation text.

What the top violations mean for a tenant

Paperwork violations lead the list

The top two are administrative. HPD requires owners of rental buildings to file a Bed Bug Annual Report each December, covering the prior November through October, and to give tenants the filing receipt or post it in the building. Order 1507 is the Class A violation for not filing. Order 780 is the Class I violation for an owner who has not filed a valid property registration. HPD says an unregistered owner cannot certify violations or start a nonpayment case to recover an apartment until the building is registered, and Local Law 71 of 2023 set civil penalties of $500 to $5,000 depending on building size.

Neither is a repair you can see, but both show up on a building's record and tell you whether the owner keeps up with required filings. See how to read a building's HPD registration.

Self-closing doors are the top Class C violation

Order 530, a self-closing door with missing or broken hinges, closer or latch, was the most common immediately hazardous violation in 2025, at 64,101. In the violation text we sampled, it covers apartment entrance doors as well as fire doors in public halls, vestibule doors and compactor chute doors, all of which help keep fire and smoke from spreading. HPD gives owners 14 days to correct it, shorter than the 21 days for pests, mold, lead paint and window guards.

Pests, mold and leaks

Roaches (order 568) and mice (order 569) together produced 58,750 Class C violations. Mold under order 550 appears twice in the top 25: as Class A when the affected area is under 10 square feet and Class B when it is more than 10 square feet, for a combined 34,359. Water leaks (order 583) added 26,062 more. If you have any of these, see your landlord's duty on pests and mold rules under Local Law 55.

Safety devices

Missing or defective carbon monoxide detectors (order 1503) and smoke detectors (order 702) produced 57,335 Class B violations. Both are on HPD's 30-day correction clock. Our guide to smoke and CO detector rules explains who installs and maintains them.

Heat and hot water

Three heat and hot water orders made the top 25: no hot water (670), inadequate heat (666) and no ready access to the heating system (672), which in the records we sampled is usually a locked boiler room door. Together they account for 37,174 Class C violations. HPD gives owners no correction period for heat and hot water violations. Know the legal temperatures or check them with the heat season temperature checker.

Class mix of the top 10

Half of the top 10 rows are Class B (hazardous), and together they make up the largest bar, 214,299 violations. Class C contributes two of the top 10 (self-closing doors and roaches), Class A two (bedbug filings and painting public halls) and Class I one (registration).

The top 25

Together the top 25 cover 699,085 violations, or 76% of everything HPD recorded from 2025 inspections.
