HPD violations in NYC: what they are and how they work

Last reviewed Oct 6, 2026 · HPD violations and complaints

An HPD violation is a finding by the Department of Housing Preservation and Development that a residential building breaches the Housing Maintenance Code. It is issued against the building, classified A, B or C by severity, carries a deadline to correct the condition, and stays open until the correction is certified or confirmed.

Where HPD violations come from

Almost every HPD violation starts with an inspection, and most inspections start with a complaint. A tenant reports no heat, a leak, mould, pests or a broken lock, usually through 311. HPD sends an inspector. If the inspector finds the condition, a violation is written.

Some inspections are not complaint-driven. HPD inspects proactively under programmes aimed at buildings with a history of conditions, and an inspector in a building for one complaint can cite conditions they observe on the way.

The violation is recorded against the building and the specific apartment or common area where the condition was found. It is the owner’s responsibility, regardless of who caused the condition or whether the tenant has since moved.

The three classes

The class is assigned by the inspector according to the condition cited, and it sets the clock.

ClassMeaningPeriod to correct
ANon-hazardous90 days
BHazardous30 days
CImmediately hazardous24 hours

Certain conditions carry their own rules. Lead-based paint hazards and some heat and hot water conditions are treated more urgently than the class alone would suggest.

Correction, then certification

Correcting the condition is the first half. Telling HPD you corrected it is the second, and it is the half owners skip.

An owner certifies that a violation has been corrected, within the window HPD sets for that violation. A certification filed on time can close the violation without a re-inspection. Miss the window and the violation stays open even though the work is done — which is why buildings routinely show open violations for conditions that were fixed years ago.

Certification is only available to a building that is properly registered with HPD. Registration lapses are a frequent and avoidable reason an owner cannot close a violation they have genuinely corrected.

Certifying a correction that was not made is a false certification, and HPD treats it as a distinct and more serious matter than the original violation.

What an open violation actually costs

Rarely one thing. The exposure accumulates in ways that are easy to miss.

Civil penalties
Penalties attach to uncorrected violations, and the schedule depends on class and on how long the condition has been outstanding. HPD publishes the current amounts; they change, so check rather than assume.
Emergency repair charges
Where a condition is serious and uncorrected, HPD can arrange the repair and bill the owner. Those charges are usually far above what the work would have cost privately, and unpaid charges can become a lien.
Litigation
Open violations support tenant actions in Housing Court and can lead to orders to correct, with penalties for non-compliance.
Transactions
Lenders and buyers look. Open Class C violations in particular tend to hold up a closing or move money into escrow until they are cleared.

Common questions

Who is responsible for an HPD violation, the owner or the tenant?

The owner. HPD issues violations against the building and looks to the registered owner to correct them, even where a tenant caused the condition or is refusing access. Access problems are handled through a separate process rather than by the violation being withdrawn.

Do HPD violations ever expire on their own?

No. They remain open until corrected and closed. Time alone does nothing except increase the penalty exposure and the likelihood that the violation surfaces at an inconvenient moment.

Can a violation be issued without anyone inspecting the apartment?

Most violations follow an inspection. Some conditions can be cited from common areas or from the exterior. If an inspector could not gain access, that is usually recorded as such rather than producing a violation for the unseen condition.

What is the difference between an HPD violation and a DOB violation?

HPD enforces the Housing Maintenance Code — living conditions in residential buildings. DOB enforces the Building Code and related rules — construction, equipment, structural and property-maintenance matters. A building can have both, and they are tracked in different systems.
