Waterbury, CT Building Safety: Plumbing Permits (2026)

City of Waterbury Code of Ordinances Chapter 156 governs plumbing work citywide, and its Permit Provisions subpart makes the permit step mandatory before construction starts. 20, the plumber must submit a written application to the City Engineer describing the work contemplated, where it is located, and when it is to be commenced, and that description must satisfy the City Engineer before a written permit is issued; no work may begin before the permit is received. 11. The fee must be paid to the Tax Collector, who issues a receipt, and a licensed plumber must present that receipt before the permit is handed over.

22 layers on additional permit and licensing controls for specific work: only licensed master plumbers may obtain permits to install range boilers and water heaters, issued by the Plumbing Inspector at the same fee charged for a plumbing fixture, and no one may connect to a water pipe or alter, add to, or install a water heater without being licensed as provided by law and holding a certificate of competency. 03 separately requires that plumbing work remain uncovered until the City Engineer inspects it, with inspection due within two working days of notice that the work is ready.

These permit and inspection duties sit on top of, not instead of, the state-adopted technical plumbing code administered under Connecticut's Building Code framework; Chapter 156 addresses Waterbury's own permit, fee, and inspection procedure for drainage and plumbing installations.
