HPD Violations in NYC: What Every Landlord Needs to Know (2026)

NYC issued 895,457 HPD violations in FY2024 — a 24% surge from the prior year. That's nearly 2,500 violations every single day. And starting in December 2023, Local Law 71 increased penalties across the board, with fines climbing as high as 10 times their previous levels. A single uncorrected Class C violation at a 5-unit building can now cost up to $1,200 per day.

Most NYC landlords don't think about HPD violations until they receive one. By then, correction deadlines are already ticking, fines are compounding, and tenants may be preparing to withhold rent. Whether you're dealing with an active violation or trying to stay ahead of enforcement, this guide covers everything you need to know — violation classes, correction timelines, updated penalties, how to clear violations through eCertification, and how to prevent them in the first place.

What Are HPD Violations?

An HPD violation is a notice issued by the NYC Department of Housing Preservation and Development when a building fails to meet the standards set by the NYC Housing Maintenance Code or the New York State Multiple Dwelling Law. HPD is the largest municipal housing agency in the United States, and every violation it issues becomes public record — searchable by buyers, lenders, insurers, and tenants in seconds.

The process that leads to a violation typically follows this path:

1. Tenant files a complaint via 311 (online or phone)
2. HPD contacts the managing agent and gives them a chance to resolve it
3. HPD calls the tenant back to check if the condition was corrected
4. If unresolved, a uniformed Code Enforcement inspector is dispatched
5. Inspector confirms the condition and issues a Notice of Violation (NOV) classified by severity
6. NOV is mailed to the managing agent with a repair deadline

There are currently over 946,000 open violation records in the NYC system. If you own a building in New York City, the question isn't whether you'll encounter HPD violations — it's whether you'll be prepared when you do.

HPD Violation Classes: A, B, and C

Every HPD violation is classified into one of three hazard classes. The class determines your correction deadline, the potential fines, and how aggressively HPD will enforce.

Class B violations are the most common, accounting for roughly 48% of all violations issued. Class C violations — the most urgent — make up about 33%. Together, B and C violations surged 32% in FY2024, outpacing the overall 24% increase.

Two special cases to know: lead paint violations and window guard violations both carry 21-day correction windows instead of the standard 24 hours, even though they're classified as Class C.

The 10 Most Common HPD Violations

Understanding what gets flagged most often helps you prioritize inspections and preventive maintenance. These are the violations NYC landlords encounter most frequently, based on 311 complaint data and HPD enforcement records.

Heat and hot water complaints alone accounted for 47% of the top five complaint categories in 2024 — more than the next four combined.

HPD Violation Penalties: What Landlords Actually Pay

Local Law 71 of 2023, effective December 8, 2023, overhauled HPD's penalty structure. Most online guides still reference the old numbers. Here's what landlords actually face today.

The math gets serious fast. A single Class B violation left uncorrected for 60 days past its deadline could generate up to $15,000 in fines — before OATH surcharges or interest.

If you miss your OATH/ECB hearing — and nearly half of all summonses result in default because owners miss the 30-day response window — you're hit with the maximum penalty plus a 25% to 75% surcharge plus 9% annual interest. Those unpaid amounts become liens on your property.

How to Check HPD Violations on Your Building

Every NYC landlord should know how to look up their building's violation history — and should check it before any transaction.

Step-by-step on HPD Online (hpdonline.nyc.gov):

1. Navigate to HPD Online
2. Search by address (house number + street + borough), BBL, or BIN
3. Click the Violations tab
4. Review each violation: class, date issued, description, current status (open/closed), apartment or location

While you're there, also check the Complaints tab (shows pending 311 complaints that haven't been inspected yet) and verify your Property Registration is current — you'll need it to certify corrections.

How to Clear HPD Violations

Clearing a violation is a four-step process: fix, document, certify, wait.

Step 1: Correct the condition. Address the issue within the deadline on your NOV. Use licensed contractors where required (lead abatement, mold remediation over 10 square feet).

Step 2: Document everything. Timestamped before-and-after photos, contractor invoices, work orders, and receipts. This documentation protects you if HPD challenges your certification.

Step 3: Certify the correction. Use eCertification (webapps.hpdnyc.org/eSignature) — it's free, digital, and the fastest path. You'll need current Property Registration and must be a named owner, officer, or managing agent.

Step 4: Wait for the 70-day window. After certification, HPD has 70 days to re-inspect. If they confirm the correction — or don't re-inspect within that window — the violation closes automatically.

This process is straightforward when you're dealing with a single violation. But when you're tracking correction deadlines across 20 or more units, coordinating multiple vendors, filing certifications on different timelines, and maintaining documentation for each — it becomes a full-time compliance operation. That's where professional property management changes the equation.

When Violations Escalate: AEP, Emergency Repairs, and Housing Court

An uncorrected violation doesn't just sit there — it triggers an escalation chain that gets progressively more expensive and harder to reverse.

AEP is the nuclear option. HPD selects approximately 250 buildings each year based on their five-year ratio of open hazardous violations. In the 2025 cycle, those 250 buildings collectively had 53,986 open violations and $4.5 million in unpaid penalties. The fees alone — $500 per unit every six months — add up to $20,000 for a 20-unit building before a single repair is made. And when HPD files an AEP Order to Correct with the County Clerk, it shows on your title.

In February 2026, the Mamdani administration announced stricter AEP enforcement, signaling that the program will continue to expand.

Meanwhile, tenants have their own recourse. Under NYC's warranty of habitability, tenants can withhold rent, sue for abatement (courts typically award 10% to 50% reductions), and file HP Actions in Housing Court ordering the landlord to make repairs. Retaliatory eviction within six months of a tenant complaint is illegal under NYC landlord-tenant law, and the eviction process itself takes 6 to 12 months and costs $30,000 to $70,000 — making prevention far cheaper than litigation.

The bottom line: 59% of HPD violations carry over from year to year. They don't expire, they don't go away, and the longer they sit, the more they cost.

How Violations Affect Sales, Refinancing, and Insurance

HPD violations don't just generate fines — they directly affect your building's value and your ability to transact.

Sales: Open Class B and C violations show up in every buyer's due diligence. They trigger price reductions, remediation escrow holdbacks, and in some cases kill deals outright. An AEP Order to Correct is filed with the County Clerk and appears on title searches.

Refinancing: Lenders scrutinize violation histories during underwriting. A pattern of open violations can prevent refinancing entirely or result in unfavorable terms. For portfolio owners, one building's violations can affect lending across the entire portfolio.

Insurance: Insurers review violation records at renewal. Repeated or severe violations lead to premium increases, non-renewal, or being dropped altogether — forcing you into high-risk coverage at significantly higher rates.

We've seen this firsthand. One Greenwich Village building we took over had 23 active ECB violations and $135,000 locked in lender escrow because of them. Within 90 days, we cleared every violation, secured the full escrow release, renovated 6 vacant units, and turned the building from negative $20,000 per month to positive $35,000 per month in cash flow — a $55,000 monthly swing.

Preventing HPD Violations: A Landlord's Checklist

The most cost-effective approach to HPD violations is preventing them in the first place. Buildings with systematic, proactive maintenance programs generate far fewer violations than those that operate reactively — waiting for tenant complaints or 311 calls to surface problems.

Beyond the schedule, three practices make the biggest difference:

1. Document everything. Keep inspection records for at least three years with timestamped photos. If a tenant challenges a certification, your documentation is your defense.
2. Respond to maintenance requests within 24 hours — even if the repair takes longer. Tenants who feel heard rarely escalate to 311. Response time matters more than resolution time.
3. Maintain a compliance calendar tracking every recurring deadline — heat season start, annual LL55 inspections, window guard notices, smoke detector checks, and lead paint testing cycles.

This checklist is manageable for a single building. Multiply it across a portfolio of 10, 20, or 50 units spread across multiple buildings — each with different inspection schedules, violation histories, and vendor needs — and it becomes clear why building owners with portfolios don't handle this alone. Systematic violation prevention and rapid response is exactly what professional property management delivers.

Staying Ahead of HPD Enforcement

HPD enforcement is at an all-time high. The agency hired 100 new inspectors in FY2023-2024, violations surged 24%, and Local Law 71 made the financial consequences of non-compliance significantly steeper. The Certification Watchlist and expanded AEP signal that this trajectory is continuing.

Whether you're clearing existing violations or building systems to prevent them, the playbook is the same: know the classification and deadlines, track your building's status on HPD Online, certify corrections promptly through eCertification, and maintain the proactive maintenance schedule that keeps inspectors from finding problems in the first place.

For landlords managing their own buildings, this guide gives you the framework. For those who'd rather focus on the investment while someone else handles the compliance — from violation tracking to vendor coordination to eCertification filing to tenant screening that reduces complaints at the source — that's what we do.
