HPD Violation Classes A, B, and C Explained

If you own residential rental property in New York City, HPD violations are part of the landscape. The Department of Housing Preservation and Development enforces the Housing Maintenance Code, and when they find a problem — or a tenant calls 311 to report one — they classify the violation into one of three classes: A, B, or C.

The class determines how urgently you need to act. Getting this wrong can turn a minor issue into a major headache.

Class A: Non-hazardous

Class A violations are the least severe. They involve conditions that are not considered dangerous to health or safety but still violate the Housing Maintenance Code.

Common examples:

• Missing or broken address numbers on the building
• Peeling paint in common areas (in buildings built after 1960, so lead paint is not a concern)
• Minor cracks in walls or ceilings
• Missing or damaged mailboxes
• Defective doorbell or intercom in non-emergency situations

Correction deadline: 90 days

You have 90 days from the date the violation is placed to correct the condition. After the deadline, HPD may re-inspect. If the condition has not been corrected, they can issue additional violations or pursue legal action.

What actually happens in practice: Class A violations are the lowest enforcement priority for HPD. Re-inspections are not automatic — they usually happen if the tenant files another complaint. Many Class A violations eventually close on their own after a period of time if no further complaints are filed. That said, do not ignore them. A building with a long list of uncorrected Class A violations looks bad to potential buyers, lenders, and insurance companies.

Class B: Hazardous

Class B violations are conditions considered hazardous to health or safety, but not immediately life-threatening.

Common examples:

• Broken or defective window in occupied space
• Mice or rat infestation (not an isolated sighting — evidence of active infestation)
• Leaking pipes or faucets
• Mold in non-severe cases
• Missing window guards where required (children under 11 in building)
• Broken or missing smoke detector
• Peeling paint in pre-1960 buildings where children under 6 reside (lead paint concern)
• Defective or missing light fixtures in common areas
• Cracked or broken floor tiles creating a trip hazard

Correction deadline: 30 days

You have 30 days to correct the condition. This is a tighter window than Class A, and HPD takes Class B violations more seriously.

The lead paint factor: In buildings built before 1960 where a child under 6 lives, peeling paint is classified as Class B specifically because of lead paint risk. This triggers Local Law 1 requirements. If you receive a lead paint Class B violation, address it immediately using certified lead-safe work practices. The liability exposure from lead paint violations is significant — personal injury lawsuits from lead exposure can reach six or seven figures.

Re-inspection: HPD is more likely to conduct follow-up inspections for Class B violations, especially for pest infestations and window guard issues. If the condition persists after the 30-day deadline, expect a re-inspection and potentially a new violation or referral to housing court.

Class C: Immediately hazardous

Class C is the most serious classification. These are conditions that pose an immediate risk to life, health, or safety and require emergency correction.

Common examples:

• No heat during heating season (October 1 — May 31)
• No hot water
• No cold water or no running water at all
• Gas leak or defective gas equipment
• Lead paint hazard in apartment with child under 6 (active peeling, not just present)
• No electricity in occupied unit
• Severe fire safety deficiencies (blocked egress, missing fire escape)
• Sewage backup
• Collapsed or imminently dangerous structural condition
• Carbon monoxide detector missing or defective

Correction deadline: 24 hours

You have 24 hours to correct a Class C violation. This is not a suggestion — it is a legal requirement. Failure to correct within 24 hours can result in:

• HPD performing Emergency Repair Program (ERP) work and billing you for it (often at 2-3x market rate)
• Referral to housing court
• Civil penalties up to $1,000 per day for heat violations
• HP (Housing Part) actions where a judge orders correction

Heat and hot water: The most common Class C violations are for inadequate heat and hot water during heating season. The legal minimums are:

• Between 6 AM and 10 PM: indoor temperature must be at least 68°F when outdoor temperature falls below 55°F
• Between 10 PM and 6 AM: indoor temperature must be at least 62°F regardless of outdoor temperature
• Hot water must be supplied at a minimum of 120°F, 24 hours a day, year-round

A single 311 complaint about no heat triggers an HPD complaint, which leads to an inspection (often the same day during peak heating season), which leads to a Class C violation if confirmed. During cold snaps, HPD processes thousands of these daily.

The correction and dismissal process

Once you correct a violation, the process to get it officially dismissed depends on the class:

Self-certification (Class A and B): For Class A and B violations, you can certify the correction yourself through HPD Online. Log into the HPD portal, find the violation, and submit a certification of correction with a description of the work performed and the date of correction. HPD may conduct a re-inspection to verify, or the violation may close automatically after the certification.

Re-inspection required (Class C): Class C violations generally require an HPD re-inspection to verify correction. You can request a re-inspection through HPD Online or by calling the borough office. Keep in mind that HPD inspectors have heavy caseloads, so re-inspections may take days or weeks to schedule. In the meantime, the violation remains open on your record.

Automatic closure: Some violations close automatically after a specific period if no further complaints are filed and no re-inspection finds the condition uncorrected. The timeline varies by class — typically 6-12 months for Class A and 3-6 months for Class B. Class C violations do not auto-close.

What happens when you miss the deadline

Missing correction deadlines triggers a cascade of consequences:

Additional violations. HPD can place new violations for the same condition, each with its own deadline. A single uncorrected leak can generate multiple violations over time.

Housing court referral. HPD can refer the case to Housing Court, where a judge can order correction and impose civil penalties. Housing court orders are enforceable — failure to comply can result in contempt of court.

Emergency repairs. For Class C conditions that threaten health or safety, HPD can send contractors to make emergency repairs and bill the property owner. These charges become a lien on the property if unpaid. ERP charges are typically 2-3 times what the repair would cost if you hired your own contractor.

Rent reduction. Tenants can apply for rent reductions through the DHCR (Division of Housing and Community Renewal) based on reduced services caused by uncorrected violations. If granted, the rent reduction remains in effect until the condition is corrected and the agency verifies the repair.

Impact on your property

HPD violations are public record. Anyone can look them up through HPD Online or through tools like Pijexa's free compliance checker. This matters because:

• Buyers and their attorneys check HPD violation history before purchasing. A long list of open violations reduces the sale price or kills the deal.
• Lenders review violation history during refinancing. Open Class C violations can delay or block a loan closing.
• Insurance companies may increase premiums or decline coverage for buildings with persistent violation histories.
• Tenant attorneys use violation histories in housing court to support claims for rent reductions, lease renewals, and harassment cases.

Staying on top of HPD violations

The most effective approach is simple: respond to tenant complaints quickly and fix issues before they become violations. A repaired leak is a maintenance item. An unrepaired leak reported to 311 is an HPD violation with a deadline and a public record.

For buildings with multiple units, check your HPD violation status regularly. You can look up any building at hpdonline.nyc.gov, or use Pijexa's compliance check tool to see violations across all NYC agencies — DOB, HPD, ECB, and FDNY — in one place. Automated monitoring through Pijexa alerts you the same day a new violation is placed, so you can act before deadlines pass and fines accumulate.

The landlords who spend the least on violations are not the ones who fight every citation. They are the ones who fix problems fast enough that violations rarely get placed in the first place.
