Kings County, NY Code Violation Reporting: How to Report (2026)

Kings County (Brooklyn) is one of the five boroughs of New York City, and all code enforcement is handled by NYC agencies. The primary reporting method is NYC 311 — residents call 311, visit the 311 website at portal.311.nyc.gov, or use the NYC 311 mobile app. Different agencies handle different violation types: the NYC Department of Buildings (DOB) addresses illegal construction, work without permits, unsafe structures, and building code violations. The Department of Housing Preservation and Development (HPD) handles housing maintenance complaints in residential buildings (heat, hot water, pests, mold, structural issues). The FDNY handles fire code violations. The Department of Sanitation (DSNY) handles trash and recycling violations. The Department of Environmental Protection (DEP) handles noise complaints. Each complaint generates a Service Request number for tracking. DOB complaints can also be filed directly through the DOB website at nyc.gov/buildings. The DOB relies heavily on 311 complaints for its enforcement actions. Brooklyn has DOB borough offices for in-person permit and violation inquiries. All DOB, HPD, and ECB (Environmental Control Board) violations are public records searchable through the Buildings Information System (BIS).
