The International Plumbing Code, 2021 edition, published by the International Code Council, a copy of which shall be filed in the office of the city secretary and available for public inspection, is hereby adopted, the same as if copied at length herein, subject to the deletions and amendments enumerated in section 28-57.

Full Breakdown
The city adopted the 2021 International Plumbing Code (IPC) by ordinance, filed with the city secretary, governing all plumbing installation, alteration and repair citywide. The Building Safety Department administers and enforces it. Every plumbing permit issued expires and becomes void if work isn't started within 180 days of issuance, or if it's suspended or abandoned for 180 days. Permit fees follow the city's adopted fee schedule, and anyone who starts plumbing work before pulling the required permit still owes those fees. Required inspections include underground, rough-in, and final, each covering testing of the underground plumbing before it's covered or the building is occupied.
Violations & Fines
Working without a required plumbing permit still triggers full permit fees under Sec. 28-57(4); most Code violations not otherwise addressed carry up to a $500 fine per Sec. 1-12, with each day a separate offense.
