NYC Department of Buildings (DOB) Violations

What Is the Department of Buildings?

The NYC Department of Buildings (DOB) is the primary agency responsible for ensuring the safe and lawful use of buildings and properties across the five boroughs. DOB enforces the NYC Building Code, the NYC Zoning Resolution, and the NYC Energy Conservation Code. From new construction permits to demolition oversight, DOB touches virtually every aspect of building development and maintenance.

DOB employs hundreds of plan examiners and inspectors who review construction plans, issue permits, conduct inspections, and enforce compliance. The agency processes over 100,000 construction permit applications annually and conducts hundreds of thousands of inspections each year across residential, commercial, and industrial properties.

DOB's jurisdiction covers everything from a homeowner's kitchen renovation to the construction of a 90-story skyscraper. The agency regulates structural integrity, fire protection, plumbing, electrical systems, elevators, boilers, facades, scaffolding, cranes, and construction site safety. If it's part of a building in NYC, DOB has authority over it.

DOB's Jurisdiction & Scope

DOB's authority extends to virtually every building in New York City, with some notable exceptions. One- and two-family homes are subject to less stringent requirements than commercial or multi-family buildings, but are still under DOB's oversight. Key areas of jurisdiction include:

Limitations of DOB

Despite its broad authority, DOB has important limitations that property owners should understand:

• DOB does not adjudicate violations itself — monetary penalties are handled by the Environmental Control Board (ECB) at OATH hearings.
• DOB does not enforce the Housing Maintenance Code — that's HPD's domain. Tenant habitability complaints go to HPD, not DOB.
• DOB does not regulate fire safety equipment directly — FDNY handles fire alarm, sprinkler, and standpipe inspections.
• DOB cannot grant zoning variances — those require applications to the Board of Standards and Appeals (BSA).
• DOB inspectors have limited ability to enter occupied residential units without consent or a warrant, except in emergencies.
• DOB does not handle environmental contamination — DEC and DEP cover hazardous materials and water/sewer issues.

DOB Violation Classes

DOB violations are classified by severity. Each class carries different correction timeframes and penalty structures. When a DOB inspector issues a violation, it's recorded in the Building Information System (BIS) and remains on the property's record until formally resolved.

Types of DOB Violations by Code

Inspectors issue violations when a property or construction doesn't comply with the NYC Construction Codes, Zoning Resolution, or other applicable laws. Each violation number contains a code prefix that identifies the violation type. The following table lists all official DOB violation codes:

Note: An asterisk (*) next to a violation code means it has been dismissed.

Why DOB Issues Violations

DOB violations are typically triggered by one of several mechanisms: routine inspections, complaint-driven investigations (often filed via 311), permit audits, or proactive enforcement sweeps targeting specific building types or neighborhoods. Understanding how violations originate helps property owners take preventive action.

Common Reasons for DOB Violations

How BVS Handles DOB Violations

Many DOB violations are accompanied by ECB summonses that carry monetary penalties adjudicated at OATH. Resolving the DOB violation alone doesn't automatically dismiss the ECB penalty — both must be addressed. BVS handles both tracks simultaneously to achieve complete building violation removal.
