If you own residential property in New York City, sooner or later you'll encounter the acronym HPD — the city's Department of Housing Preservation and Development. HPD enforces the NYC Housing Maintenance Code, and when a building falls short of it, the agency issues a violation. For a Brooklyn landlord, understanding how HPD violations work — what triggers them, how they're classified, and how to clear them — is one of the most practical skills you can have. Handled well, a violation is a routine fix. Ignored, it becomes daily penalties, a public record, and in the worst cases city-ordered repairs billed back to you.
Here's how the system works and how to stay ahead of it.
What is an HPD violation?
An HPD violation is an official finding that a condition in your building fails to meet the NYC Housing Maintenance Code. Violations are usually issued after an inspection — and most inspections are triggered by a 311 complaint from a tenant. An inspector visits, documents the condition, and enters a violation into HPD's system with a class, a description, and a deadline to correct it.
Violations attach to the building, not to you personally, but you as the owner are responsible for correcting them and certifying the fix. They're also public: anyone can look up a building's open violations through HPD Online, which means prospective buyers, lenders, and tenants can see them too.
Before HPD can even issue and enforce most violations, your building must be properly registered with the agency. If you haven't registered — or your registration lapsed — that's its own problem. See our HPD registration guide for how to get and stay current.
The three classes of HPD violations
HPD classifies every violation by how serious the hazard is. The class determines how quickly you must fix it and how large the penalties can be.
- Class A — Non-hazardous. Minor conditions such as a small ceiling crack, a missing or peeling paint spot in a common area, or a missing required sign. These generally carry a 90-day correction period.
- Class B — Hazardous. More serious conditions like a broken window, a leaking faucet, inadequate lighting in a public hallway, or a defective self-closing door. These come with a shorter correction window (typically around 30 days).
- Class C — Immediately hazardous. The most serious category: no heat or hot water, lead-based paint hazards where a child under six lives, mold, pest and rodent infestations, a broken or missing smoke/carbon-monoxide detector, or a lack of working locks. Class C violations must be corrected almost immediately — often within 24 hours for heat and hot water — and they carry the highest daily penalties.
There's also a fourth designation you may see: certain lead-paint conditions are treated as Class C "immediately hazardous" with especially strict testing and documentation rules. If your building predates 1960 and a young child lives in a unit, treat every peeling-paint report as urgent.
The takeaway: not all violations are created equal. A Class A sign issue and a Class C no-heat violation live in the same system but demand very different urgency.
The most common violations Brooklyn landlords see
Across the Brooklyn buildings we manage, the same handful of issues drive most violations:
- Heat and hot water. During heat season (October 1 through May 31), landlords must maintain minimum indoor temperatures, plus hot water year-round. Heat complaints are among the most-filed and most-enforced in the city. Our heat and hot water requirements guide breaks down the exact thresholds.
- Peeling paint / lead. In pre-1960 buildings with a child under six, peeling paint is presumed to be a lead hazard until proven otherwise.
- Pests. Roaches, mice, rats, and bedbugs. NYC also has an annual bedbug-filing requirement.
- Mold and leaks. Water intrusion left unaddressed becomes mold, which escalates the hazard class.
- Smoke and CO detectors. Missing or non-working detectors are immediately hazardous.
- Defective doors, locks, and windows. Especially self-closing entry doors and window guards where children live.

Why rent-stabilized and subsidized buildings need extra care
If you own rent-stabilized or subsidized housing, HPD compliance carries higher stakes. Open violations can interfere with rent increases, MCI and IAI eligibility, and the standing of subsidy contracts. Housing-inspection failures in a subsidized unit can jeopardize a tenant's assistance — and, by extension, your rental income. In these buildings, a clean HPD record isn't just about avoiding penalties; it's tied directly to what you're allowed to collect and how smoothly your subsidy relationships run.
This is one of the areas where generalist management falls short and specialized experience pays off. Keeping violations closed, inspections passed, and subsidies intact takes a team that lives in this world — which is precisely the niche Yak Management was built around.
How to fix an HPD violation, step by step
Clearing a violation is a two-part job: do the work, then prove it. Here's the sequence.
1. Read the violation carefully
Every violation lists the class, the specific condition, the apartment or common area, and the correction deadline. Don't guess — the notice tells you exactly what the inspector found and by when it must be resolved.
2. Actually correct the condition
Fix the underlying problem completely, using a qualified contractor where the work requires one (electrical, plumbing, lead abatement). Cutting corners here is how landlords end up with a re-inspection failure or a false-certification problem. This is where responsive, well-coordinated maintenance earns its keep.
3. Certify the correction with HPD
For most Class A and B violations, HPD requires you to file a certification of correction — a notarized statement, often with supporting documentation, submitted within the correction window. Certifying tells HPD the condition is fixed and asks the agency to close the violation. HPD may inspect to verify.
4. Request a dismissal if the violation is wrong or already fixed
If a violation was issued in error, duplicates an existing one, or was corrected before it was even entered, you can request a dismissal rather than a certification. Keep your before-and-after documentation.
One firm rule: never certify a violation as corrected unless the work is genuinely complete. False certification is illegal and can trigger additional penalties and inspections. When in doubt, fix first, certify second.
What happens if you ignore an HPD violation
Ignoring a violation doesn't make it disappear — it makes it more expensive:
- Daily civil penalties accrue, and they're highest for Class C conditions.
- HPD's Emergency Repair Program (ERP) can send the city's own contractors to make the fix and bill you, usually at a premium, with the charge becoming a lien if unpaid.
- The Alternative Enforcement Program (AEP) targets the most distressed buildings for intensive oversight and fees.
- Open violations complicate any sale or refinance and can sour tenant relationships.
None of this is exotic. It's the predictable cost of letting a fixable condition sit. Staying current on your broader obligations — covered in our NYC landlord obligations guide and our complete landlord-tenant law guide — keeps you out of this cycle entirely.
How to avoid HPD violations in the first place
The best violation is the one that never gets issued. In practice, that comes down to two things: maintenance that stays ahead of problems and communication that keeps small issues from escalating into 311 calls.
- Respond fast. Most violations begin as an unanswered repair request. A tenant who feels heard rarely calls 311.
- Inspect proactively. Seasonal and turnover inspections catch peeling paint, failing detectors, and early leaks before an HPD inspector does. That's the whole point of routine property inspections.
- Winterize before heat season. Service boilers and heating systems before October 1 so you're not scrambling during the first cold snap.
- Keep documentation. Log every request, repair, and inspection. If a violation is ever contested, your records are your defense.
This is exactly the discipline our full-service property management is built around — and it matters even more for rent-stabilized and subsidized buildings, where compliance and inspections are constant. Deep HPD and rent-stabilization expertise is core to how we operate.
The bottom line
HPD violations are a manageable part of owning NYC rental property — as long as you understand the classes, correct conditions promptly, certify honestly, and, ideally, prevent violations through proactive maintenance. If your Brooklyn building already has open violations, or you'd simply rather never have to think about certifications and correction deadlines again, that's what we do every day.
