Trenton Building Department | Permits, Inspections & Contact

Trenton’s Division of Technical Services, under the Construction Official, is the municipal office that issues building, plumbing, electrical, and fire-protection permits and reviews plans. The Division of Inspections enforces the city’s construction, housing, zoning, electrical, plumbing, and fire requirements. Mercer County is the geographic county and is not the issuer of a Trenton building permit.

Trenton building permits and plan review

Use Trenton’s official Apply For page for the Construction Permit Application and the city’s Forms Center for UCC technical sections and zoning forms. The Technical Services division says new construction and many alterations require plans reviewed by the relevant technical personnel. Major renovations or changes of use should be coordinated with the city’s Project Application Review Committee and zoning staff.

Inspections, code compliance, and certificates of occupancy

Trenton’s inspectors enforce the New Jersey Uniform Construction Code and Uniform Fire Code. The city states that permits are followed by inspections at the required stages, with a final inspection and certificate issued when work has been completed properly. The Division of Inspections handles rules governing use and occupancy, while zoning and planning approvals can be separate prerequisites.
