New Haven Trade, Obstruction, and Certificate Permit Guide

New Haven electrical, plumbing, HVAC, sign, demolition, obstruction, certificate of occupancy, and certificate of approval steps are handled through electronic permitting.

Permit takeaway

New Haven's permit fee page covers building, sign, electrical, plumbing, and HVAC permits, with demolition, certificates of occupancy, certificates of approval, and revised estimate fees handled separately.

Zoning and placement

City right-of-way work or equipment such as sidewalk closures, dumpsters in the street, scaffolding, lifts, or work over sidewalks and streets requires an obstruction permit.

Building and trade review

When a permit changes the building use, a Certificate of Occupancy is required; other completed permitted work may require a Certificate of Approval or Certificate of Completion after inspections pass.
