Do I need a permit for accessory dwelling unit (adu) in Bridgeport?

Permit required

Yes. In Connecticut, accessory dwelling unit (adu) generally requires a permit, and Bridgeport is no exception.

CGS 8-2o requires town zoning to allow at least one accessory apartment as of right on each lot with a single-family dwelling, attached, within, or detached, unless the town opted out before January 1, 2023; no town may opt out after that date. The zoning law changes where accessory apartments are allowed, not the building code; a building permit and certificate of occupancy are still required (CGS 29-263 and 29-265). Under CGS 8-2o a town may not require fire sprinklers in an accessory apartment if they are not required for the main house, or require a separate utility connection. Zoning must decide an as-of-right accessory apartment application within 65 days unless the applicant agrees to an extension (CGS 8-2o(b)).
