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).

Bridgeport FAQ
Does Bridgeport charge impact fees on a new ADU?
No traditional impact fees. Connecticut has not enacted general impact fee authority for municipalities, so Bridgeport limits ADU costs to building permit fees under the CT State Building Code, zoning review fees, fire marshal review, and WPCA sewer connection charges ($125 single-family). Aquarion Water charges its own connection fee if a new service is needed. There is no school, parks, or transportation impact fee.
How are schools funded if not through impact fees?
Connecticut school districts are funded through the state Education Cost Sharing (ECS) grant formula (CGS Section 10-262h) plus the local mill rate on property tax. New construction contributes to schools and city services through ongoing property tax on the increased assessment after the certificate of occupancy is issued, rather than through upfront impact fees. The Bridgeport Tax Assessor reassesses after construction.
