HPD violation classes. A, B, C, with real examples and the real deadlines.
Every HPD violation gets a class. The class sets how long the owner has to fix it and how much it costs if they don't.

All three rings are drawn on one 90-day dial. The clock starts at service, generally five days after HPD mails the notice; for heat and hot water, when the violation is posted.

Penalties if it isn't corrected
HPD doesn't fine on the spot. Penalties are sought in Housing Court once the correction period passes without an HPD violation certification. Ranges for violations issued on or after December 8, 2023:
| Violation | Civil penalty |
|---|---|
| Class A | $50–$150, plus $25/day |
| Class B | $75–$500, plus $25–$125/day |
| Class C, 5 or fewer units | $150–$750, plus $50–$150/day |
| Class C, more than 5 units | $150–$1,200, plus $150–$1,200/day |
| Heat and hot water | $350–$1,250/day; $500–$1,500/day for repeat |
| Lead-based paint hazard | $250/day, up to $10,000 |
| Self-closing doors | $250–$500, plus $250/day |
On top of that: a $200 inspection fee when HPD finds heat violations on a third inspection in the same heat season, and $50–$1,000 per violation for false certification. More in the owner guide. Some B and C violations are also rent-impairing, which adds a six-month rent consequence on top of the penalty.

HPD violation classes: common questions
Short answers first. Still stuck? Call (347) 201-2336 and a person picks up.
What are the HPD violation classes?
HPD violation classes are A (non-hazardous, 90 days to correct), B (hazardous, 30 days) and C (immediately hazardous, 24 hours in most cases), and the class sets both the deadline and the penalty if the owner doesn't correct and certify in time. Class C has exceptions for heat and hot water, self-closing doors, lead paint, window guards, mold and pests. HPD Orders show on the same list as Class I.
Is a missing smoke detector Class C?
No. Missing or broken smoke detectors (order 702) and carbon monoxide detectors (order 1503) are written as Class B, with 30 days to correct. People often assume they're C.
Is mold a Class A, B or C violation?
It depends on size. Small mold patches under 10 square feet show up as Class A (order 550). Larger mold conditions are written as B or C. Class C mold gets 21 days instead of 24 hours.
When does the correction clock start?
At service. For most violations, service is complete five days after HPD mails the Notice of Violation. For heat and hot water, it's complete when the inspector posts the violation at the building.
What happened to HPD penalties in December 2023?
They went up sharply for violations issued on or after December 8, 2023. Class A went from $10–$50 to $50–$150 plus $25 a day, for example. The new ranges are in the table on this page.
What is Class I?
HPD Orders, such as Orders to Repair and Orders to Repair/Vacate, appear on a building's violation list with a hazard class of I. They aren't A, B or C housing code conditions, and each Order carries its own instructions for correcting it. HPD explains the types on its Orders page.
