Kings County, NY Code Violation Reporting: Common Violations (2026)

Brooklyn (Kings County) has one of the highest volumes of building code violations in New York City due to its dense housing stock and rapid development. The most common DOB violations include: work without a permit (construction, renovation, or demolition performed without DOB permits), illegal apartment conversions (converting basements, cellars, or single units into multiple dwelling units), unsafe building facades requiring repair under Local Law 11 (FISP — Facade Inspection Safety Program), elevator and boiler compliance issues, and failure to maintain fire safety systems. HPD violations are extremely common in Brooklyn's large rental housing stock: failure to provide heat and hot water (Class C), pest infestations including bedbugs and rodents (Class B), mold and moisture issues, lead paint violations in pre-1978 buildings, and general maintenance deficiencies. DOB also addresses illegal signs, unpermitted scaffolding, and construction site safety violations. Brooklyn has seen a surge in illegal short-term rental enforcement under Local Law 18 (2023), which requires registration with the Mayor's Office of Special Enforcement. The volume of complaints through 311 drives most DOB enforcement action.
