What an HPD Class C violation means and how it gets resolved

An HPD Class C is the most serious tier of Housing Maintenance Code (HMC) violations. The code calls it "immediately hazardous." That means the condition presents a real, present danger to health or safety, and the cure window is the shortest HPD offers — often measured in hours or a few weeks, not months.

Class C is also the tier most likely to trigger an HPD emergency repair or a Housing Court case if the owner does not respond. This guide explains what lands in Class C, the timeline, how penalties stack, and the path to closing these out. Educational only — not legal advice.

What this means

The HMC defines Class C as a condition that is immediately hazardous (HMC § 27-2115). Certain conditions are Class C by rule, even if they would not normally look "immediate" on the surface — lead paint in a unit with a young child is the most common example.

Some Class C triggers that come up repeatedly:

• Lead paint. Peeling paint in an apartment where a child under 6 resides, in a pre-1960 building (or 1960–1978 with known lead paint), is presumed hazardous and is automatically Class C (see Local Law 31).
• Heat and hot water. No heat during heat season (October 1 – May 31) or no hot water at any time is Class C (HMC § 27-2029).
• Mold. Visible mold over a threshold area or in a location affecting HVAC is a Class C under the Indoor Allergen Hazards Act (see Local Law 55).
• Egress. Broken self-closing doors, defective fire escapes, or obstructed egress paths are Class C when they affect life safety.

Lead paint with a child under 6 is automatic Class C. The cure window is much shorter than ordinary Class C and the work must be performed by an EPA lead-safe-certified firm using containment and cleaning protocols. Non-certified labor is not acceptable.

Common causes

• Peeling paint in an apartment with a child under 6 in a pre-1960 (or presumptive) building
• No heat or no hot water during the heat season
• Visible mold larger than 10 square feet or affecting HVAC
• Broken or missing self-closing hallway doors that compromise egress
• Exposed live wiring, broken window guards in apartments with young children

Timeline

• Issued. HPD issues the NOV on the day of inspection; for heat/hot water, the inspection can happen within 24 hours of a 311 complaint.
• Correction window.
  • Heat and hot water: 24 hours to correct.
  • Lead paint (child under 6): a short, defined window — typically measured in days to a few weeks, depending on XRF testing, containment, and clearance dust-wipe results (verify current HPD rule).
  • Most other Class C conditions: commonly around 21 days to correct, then certify.
• Certification. Once corrected, the owner files a Certification of Correction. For lead and mold, the certification usually requires attached documentation — XRF results, dust-wipe clearance, or a mold-remediation report.
• If unresolved. HPD can issue an Emergency Repair order, perform the work itself, and lien the building for the cost. The violation can also be packaged into a Housing Court case.

Penalties

Class C civil penalties are the highest of the three classes.

• Base fine: commonly $50 to $150 per day, per violation (HMC § 27-2115 — verify current schedule).
• Minimum starting penalty. Many Class C conditions carry a minimum penalty the day the violation issues, before daily accrual begins.
• Emergency Repair cost. If HPD performs the work, the cost is charged back to the owner and can become a property tax lien.
• False certification. Certifying correction when the condition was not fixed carries elevated penalties and personal exposure.

How it typically gets resolved

1. Treat Class C as an emergency. Do not wait on vendor scheduling — for heat and hot water especially, a same-day response is the expected posture.
2. Use qualified labor.
   • Lead paint: EPA lead-safe-certified firm (RRP rule). Containment, proper PPE, HEPA cleaning, and dust-wipe clearance are part of the record.
   • Mold (over ~10 sq ft): NYS-licensed mold assessor and NYS-licensed mold remediator; the owner cannot self-perform beyond the minor-area threshold.
   • Boiler / hot water: licensed plumber or boiler-service firm.
3. Document everything. Dust-wipe clearance results, lab reports, remediation reports, dated photos, and technician invoices are required to certify correction on the lead / mold tracks.
4. Certify correction with HPD within the cure window. Late certification does not stop penalty accrual.
5. If HPD performs Emergency Repair, pay the charge or dispute it quickly — unpaid charges become liens.

When to hire a pro

Almost every Class C benefits from professional involvement.

• Lead paint: always use an EPA RRP / lead-safe-certified firm; never in-house labor.
• Mold over the Local Law 55 threshold: NYS-licensed mold assessor and NYS-licensed remediator, with a written scope.
• Heat / hot water: licensed plumber; a mechanical engineer if the boiler is end-of-life or chronically failing.
• Housing Court or Emergency Repair charges: attorney — do not self-represent here.
