ADU Rules
Bridgeport allows ADUs as of right per CT PA 21-29. The city's existing multi-family housing stock and urban density make ADUs part of a broader affordable housing strategy for CT's largest city.
Bridgeport ADU (Accessory Dwelling Unit) Rules
Some RestrictionsADU Permits
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.

Some RestrictionsADU Impact Fees
Connecticut has no statewide development impact fee enabling statute analogous to California's Mitigation Fee Act or Washington's GMA impact fee authority. Bridgeport therefore does not charge traditional school, parks, or transportation impact fees on ADU construction. Costs are limited to building permit fees under the Connecticut State Building Code, zoning review fees, and Bridgeport Water Pollution Control Authority (WPCA) sewer connection charges (currently $125 for a single-family dwelling, $400 for multi-family up to four units).

Few RestrictionsADU Owner Occupancy
The City of Bridgeport Zoning Regulations require the property owner to occupy either the principal dwelling or the accessory dwelling unit. Connecticut Public Act 21-29 (CGS Section 8-1c) does not require or prohibit owner-occupancy at the state level — it leaves that decision to municipalities. Because Bridgeport did not opt out of the as-of-right framework, an owner-occupancy requirement is generally enforceable as a local zoning standard reasonably related to the use, but the state's silence means it must be applied even-handedly.

Some RestrictionsADU Rental Restrictions
Long-term rental of a Bridgeport ADU is permitted once the unit is approved under the Zoning Regulations and the owner satisfies the owner-occupancy condition. Tenancies are governed by the Connecticut Landlord-Tenant Act (CGS Chapter 830) and Bridgeport's Fair Rent Commission under CGS Section 7-148b. Short-term rentals (under 30 days) face zoning scrutiny and require collection of the Connecticut hotel room tax (CGS Section 12-407). Connecticut has no statewide rent control.
