DOB violations in NYC: what they are and how they are resolved
Last reviewed Oct 6, 2026 · DOB violations and permits
A DOB violation records that a building or work at it breaches the Building Code or another rule the Department of Buildings enforces. It stays against the building until resolved through the route DOB specifies for that type, and it can block permits, sign-offs and a certificate of occupancy until it is.
How DOB violations arise
DOB inspects in response to complaints, as part of required periodic inspection programmes, and during the course of permitted work. An inspector who finds a condition that breaches the code writes a violation against the building.
Unlike HPD, which is concerned with living conditions inside residential buildings, DOB is concerned with the building itself and the work done to it: structure, egress, facades, elevators, boilers, construction safety, and whether work was permitted at all.
That difference matters practically. An HPD violation is usually about something a contractor can fix in an afternoon. A DOB violation is often about something that needs a filing, an engineer or an architect, and a sign-off.
The types owners meet most often
- Work without a permit
- Work that required a permit and did not have one. Resolution usually involves legalising the work through a filing, which can be substantially more expensive than permitting it would have been.
- Failure to maintain
- The building or a part of it is not being kept in safe condition. Facades, parapets and retaining walls are common subjects.
- Illegal conversion
- Occupancy that does not match what the certificate of occupancy permits — an extra unit in a basement, a single-family house in multiple occupation. Treated seriously because of the egress and fire risk.
- Equipment and periodic inspection failures
- Elevator, boiler and facade inspection regimes have their own filing deadlines. Missing a filing produces a violation independently of whether the equipment is sound.
- Stop-work order violations
- Continuing work after a stop-work order is among the most serious things that can happen on a site and escalates quickly.
Why an open DOB violation stops other things
DOB violations are not purely financial. An open violation of certain classes prevents DOB signing off completed work, issuing a new or amended certificate of occupancy, or in some cases permitting new filings at the building.
This is how an old, forgotten violation surfaces: an owner files for routine work, and the filing will not progress until something from years ago is resolved. The cost is rarely the violation itself — it is the delay to whatever is now blocked behind it.
Common questions
Is a DOB violation the same as an ECB violation?
No. A DOB violation is a record against the building. An ECB violation is a summons returnable at OATH that carries a hearing and a penalty. One inspection can produce both, which is why they are often confused.
How long does a DOB violation stay on a building?
Until it is resolved. There is no expiry. Violations from decades ago are routinely found still open when somebody files for new work.
Can I sell a building with open DOB violations?
Legally yes, practically it depends on the buyer and the lender. Open violations are a standard diligence item and commonly end up as a price adjustment, an escrow or a condition to closing.
