New Haven Building Department | Permits, Inspections & Contact

New Haven’s Office of Building Inspection and Enforcement administers residential and non-residential construction permits within New Haven. Connecticut’s State Building Code applies statewide, while New Haven’s local building official handles the permit, inspection, and code-enforcement process for property inside the city. Nearby towns in New Haven County use their own officials and application systems.

New Haven permits and City Squared

Review the city’s Building Department Applications page before applying. The project may need zoning confirmation from the City Plan Department, construction documents, contractor information, and other department sign-offs. New Haven links applicants to City Squared for electronic permitting; use the city’s official instructions and the current City Squared workflow to submit an application or review available record information.

Inspections, plan review, and occupancy

The office reviews applications and drawings for building and safety-code compliance, issues building and related trade permits, conducts required inspections, and investigates code complaints. New Haven’s application guidance explains that a change in use can require a Certificate of Occupancy. After all required inspections pass, the inspector can provide a Certificate of Approval for work that does not require a new occupancy certificate; request the applicable certificate before occupying a changed or newly approved use.

Official contact information

The city lists the Building Official’s office at 200 Orange Street, Room 501, New Haven, Connecticut 06510, phone (203) 946-8045. Use City Squared only through the city’s linked electronic-permitting instructions, and confirm zoning approval with City Plan before relying on a building permit alone.
