Most Common HPD Violations in Brooklyn (And How to Avoid Them)

If you own a multifamily building in Brooklyn, an HPD violation is less a matter of if than when — unless you're deliberately staying ahead of the conditions that trigger them. The good news: the violations that generate the most complaints and the steepest headaches are remarkably predictable. A short list of issues accounts for the majority of what NYC's Department of Housing Preservation and Development (HPD) cites across the borough, and every one of them is preventable with responsive maintenance and good records.

Here's what Brooklyn landlords get written up for most, why each one happens, and how to keep it off your building's record.

What is an HPD violation?

An HPD violation is an official finding by NYC's Department of Housing Preservation and Development that a residential condition breaches the Housing Maintenance Code. Violations usually start with a tenant calling 311, which triggers an HPD inspection. If the inspector confirms the condition, HPD issues a Notice of Violation, sets a correction deadline, and requires the owner to fix it and certify the correction by a specific date.

Violations are graded by severity:

• Class A — non-hazardous: minor conditions like a small wall crack or a missing hallway light bulb. Longest correction window.
• Class B — hazardous: conditions like broken smoke detectors, peeling paint, or a leaky faucet. Shorter deadline.
• Class C — immediately hazardous: the serious stuff — no heat, no hot water, lead-paint hazards where a child under six lives, major leaks, or vermin infestations. Fastest deadline.
• Class I — information orders: the most serious enforcement-level orders.

Violations attach to the building, become part of the public record on HPD Online, and can surface during a sale, a refinance, or a prospective tenant's due diligence. For the full lifecycle — issuance, correction, dismissal — see our companion guide, HPD Violations: How to Avoid, Address & Resolve Them.

1. No heat or hot water

This is the single most-cited category in NYC, and it dominates complaints every winter. During heat season (October 1 through May 31), landlords must maintain minimum indoor temperatures, and hot water at a minimum temperature year-round. A cold apartment on a January night reliably generates a 311 call, and no-heat/no-hot-water findings are Class C — immediately hazardous, with the tightest correction deadline.

How to avoid it: service your boiler before heat season, not after the first cold snap. Keep spare parts and a vendor on call. During the extended winter freezes we manage through, the difference between a quick fix and a violation is often just how fast someone picks up the phone. Read the full rules in our NYC heat and hot water requirements guide.

2. Leaks, water damage, and mold

Water intrusion — a roof leak, a failed pipe, a chronically running toilet upstairs — is one of the most common conditions inspectors document, and it rarely stays a single violation. Left alone, a leak becomes water-stained ceilings, then mold, which HPD treats seriously and which is regulated under NYC's Local Law 55 (the Asthma-Free Housing Act) in units where mold or pests recur.

How to avoid it: treat every leak report as urgent, even a small one. The cheapest version of this problem is the one you fix the same week a tenant reports it. Document the repair and the date.

3. Pests — mice, roaches, and bedbugs

Vermin infestations are among the most frequent hazardous violations in dense Brooklyn housing stock. Landlords are responsible for keeping units and common areas free of pests, and bedbugs carry an additional obligation: NYC requires owners to file an annual bedbug history disclosure and provide it to tenants. Under Local Law 55, buildings must also address indoor allergen hazards like mice and roaches at turnover and on complaint.

How to avoid it: work with a licensed exterminator on a regular schedule rather than reacting infestation-by-infestation, seal entry points during turnovers, and respond to the first report — infestations spread between units fast in an attached building.

4. Peeling and lead paint

In pre-1960 buildings where a child under six lives, peeling paint is presumed to be a lead hazard and is treated as immediately hazardous. NYC's Local Law 31 requires periodic lead-paint inspections in qualifying units, and owners have annual notice and investigation obligations under Local Law 1. This is one of the most heavily enforced areas in the city, with significant penalties for non-compliance.

How to avoid it: know which of your units are pre-1960, ask about children under six annually as the law requires, address peeling paint promptly using EPA/HUD-safe practices, and keep your inspection paperwork. Our post on lead paint disclosure requirements for NYC landlords walks through the details.

5. Broken smoke and carbon monoxide detectors

Missing or non-working smoke and carbon-monoxide detectors are a classic Class B violation — easy to prevent, easy to get cited for. Landlords must install and maintain working detectors, and while tenants are responsible for replacing batteries during a tenancy, the owner must provide functioning devices at move-in and on request.

How to avoid it: test and replace detectors at every turnover, log the date, and keep signed tenant acknowledgment forms. This is exactly the kind of thing a systematic property inspection routine catches before an HPD inspector does.

6. Broken windows, doors, locks, and self-closing doors

Inspectors routinely cite defective window guards (required where a child under 10 lives), broken entry-door self-closers, non-functioning locks, and unsafe stairs or railings. Individually minor, these add up and often appear alongside a larger complaint once an inspector is already in the building.

How to avoid it: install window guards where required and confirm them annually, keep self-closing doors and locks functional, and don't let a single-condition complaint become a multi-violation inspection because the inspector spotted three other things on the way in.

Why most Brooklyn violations are really a response-time problem

Notice the pattern: almost every common violation is a maintenance issue that a tenant reported and no one fixed fast enough. The condition existed, the tenant called 311 instead of the landlord, and HPD arrived. Buildings that stay clean on HPD Online aren't the ones that never have leaks or dead detectors — they're the ones where a tenant's first call goes to a responsive manager who fixes it before it escalates.

That's the whole game, and it's why we structure management around it: tenant requests answered within 24 hours, maintenance prioritized by urgency, and immediate emergency response for heat, water, and safety issues. When a bedridden tenant in one of our buildings had refused access under prior management, rebuilding that trust and getting the repair done wasn't just good service — it's exactly how you keep a Class C violation from ever being written. Our approach to full-service property management treats compliance as the natural byproduct of simply being responsive.

How to keep your building's HPD record clean

A practical checklist:

• Register with HPD and keep it current — you can't properly respond to violations, or collect rent in housing court, without an active registration. See our HPD registration guide.
• Service the boiler before heat season and keep a heating vendor on call October through May.
• Treat every leak and pest report as urgent — same-week response, documented.
• Inspect on a schedule: detectors, window guards, locks, and lead-paint conditions at every turnover.
• Know your pre-1960 units and your lead-paint obligations under Local Law 1 and Local Law 31.
• When a violation does issue, correct and certify it by the deadline — correction alone doesn't clear the record.
• Keep records of everything — dates, vendors, tenant communications. If a dispute reaches housing court, your paperwork is your defense.

For the broader picture of what the city requires of you, our guide to NYC landlord obligations covers habitability, notices, and filings in one place. Landlords across neighborhoods like Bed-Stuy, Crown Heights, and Bushwick face the same core list — the older the housing stock, the more the fundamentals matter.

Where we come in

We specialize in exactly the buildings where HPD compliance is hardest — rent-stabilized and subsidized housing across Brooklyn — and we've built our operation around catching conditions before they become violations. If your current setup means tenants are calling 311 before they're calling you, that's a fixable problem.

Schedule a property consultation or reach out, and we'll give you a straight assessment of where your building stands and what it would take to keep its record clean.
