ADU Permits: Bridgeport vs Stratford
How do adu permits rules compare between Bridgeport, CT and Stratford, CT?
Bridgeport, CT
Fairfield County
Bridgeport allows accessory dwelling units (ADUs) in single-family residential zones (AAA, AA, R-3, R-2, A, B, C) as a permitted accessory use under the City of Bridgeport Zoning Regulations. The city did not affirmatively opt out of Connecticut Public Act 21-29 (codified at CGS Section 8-1c), so the state's as-of-right ADU framework applies as a baseline floor. Construction is reviewed under the Connecticut State Building Code (CT Supplement 2022 adopting the 2021 IBC/IRC) by the Bridgeport Building Department.

Bridgeport FAQ
Does Bridgeport allow ADUs by right?
Yes. Bridgeport permits attached and internal ADUs in single-family zones (AAA, AA, R-3, R-2, A, B, C) under the local Zoning Regulations, and the city did not opt out of Connecticut Public Act 21-29 (CGS Section 8-1c), so the state's as-of-right framework applies as a backstop. Detached ADUs require at least two acres locally. You still need zoning compliance, building, and fire marshal review through the Bridgeport Building Department.
What permits do I need?
A Zoning Compliance Application through the Bridgeport Zoning Department (filed via Park City Portal) plus building, electrical, plumbing, and mechanical permits from the Bridgeport Building Department under the Connecticut State Building Code (CT Supp 2022 adopting 2021 IBC/IRC). Smoke and CO alarms must satisfy the CT State Fire Safety Code under CGS Section 29-291. Sewer connection is handled through the Bridgeport Water Pollution Control Authority.
