Most NYC property owners know to watch for DOB violations and ECB fines. The three issues below tend to fall through the cracks — not because they’re obscure, but because they don’t generate obvious notices until they’ve already created a problem. Each one is easy to check and correct proactively.
Quick Answer
The three violations NYC property owners most commonly overlook are: HPD Property Registration (required annually for buildings with 3+ units), FDNY fire-safety violations (extinguishers, sprinklers, alarms), and DOB open permits (jobs filed but never closed out). Each one is easy to check online — and all three can delay or kill a sale if discovered late.
The 3 Most Overlooked Violations — and What They Cost You
| Violation Type | Why It Gets Missed | Consequence If Ignored | Where to Check |
|---|---|---|---|
| HPD Property Registration | Annual renewal is easy to forget; no prominent notice sent | Fines; inability to legally rent; surfaces in title searches | HPD online portal (hpdonline.nyc.gov) |
| FDNY Fire Safety Violations | Inspections happen on FDNY’s schedule — owners often unaware until sale | Fines; liability exposure; lender refusal; deal delays | FDNY inspection records (fires.nyc.gov) |
| DOB Open Permits | Contractors complete work but never file the final sign-off | Blocks future permits; flags property in title search; can delay closing | DOB NOW (dobonline.nyc.gov) |
1. HPD Property Registration
Buildings with three or more residential units in New York City are required to register with the Housing Preservation and Development (HPD) department annually. Registration must include the property owner’s name and address, as well as a managing agent if the owner doesn’t live in the building. Many owners do this once and don’t realize it needs to be renewed each year.
Failing to register — or allowing registration to lapse — results in an HPD violation on the public record. This shows up in title searches, and buyers’ attorneys will flag it. Beyond the transaction impact, an unregistered building cannot legally operate as a rental property under NYC housing law.
2. FDNY Fire Safety Violations
The Fire Department of New York conducts routine inspections of commercial and residential buildings and issues violations when fire safety requirements aren’t met. These include fire extinguisher compliance, sprinkler system condition, smoke and carbon monoxide detector requirements, and fire exit signage. Unlike DOB violations, FDNY violations don’t always generate a direct notice to the owner — they show up in FDNY’s inspection records and surface when someone runs a full compliance check.
Lenders increasingly review FDNY records as part of due diligence. An open FDNY violation can be enough to delay a mortgage commitment or require resolution as a closing condition.
3. DOB Open Permits
An open permit is a DOB permit that was filed for construction work but never received a final sign-off or letter of completion. This happens more often than most owners realize: a contractor completes the physical work, gets paid, and moves on — but never files the inspection documentation needed to close the permit in DOB’s system. Years later, the permit still shows as “active” in DOB NOW.
Open permits don’t always become violations immediately, but they create friction. They can block new permit applications on the same property, appear as flags in title searches, and require resolution before some lenders will fund. Identifying and closing out old permits before a transaction saves significant time and negotiating leverage.
Run the check before you go to market. All three of these issues — HPD registration, FDNY violations, and open DOB permits — can be identified in under an hour using public city databases. Discovering them after contract is signed creates pressure, negotiation leverage for the buyer, and sometimes escrow requirements. Finding them before listing gives you time to resolve on your own terms.

Frequently Asked Questions
What are the most commonly overlooked violations for NYC property owners?
HPD property registration lapses, open FDNY fire safety violations, and DOB permits that were never closed out are the three most frequently overlooked. None of them send obvious annual reminders — they accumulate quietly until a title search or lender review surfaces them during a transaction.
Does an open DOB permit affect a property sale?
Yes. Open permits appear in DOB NOW’s public record and surface in title searches. Lenders may require them closed before issuing a mortgage commitment. Even when they don’t block a deal outright, they create negotiating leverage for buyers and can require escrow arrangements at closing.
How often does HPD registration need to be renewed in NYC?
HPD property registration must be renewed annually for buildings with three or more residential units. Registration runs on a calendar-year cycle and must include current owner contact information and a managing agent designation if the owner does not reside in the building.
