Summary
Columbia enforces the 2021 International Plumbing Code as its local plumbing standard under Sec. 5-91, with the Code Council's administrative sections on permit authority and official qualifications carved out and replaced by the city's own building-official provisions. A plumbing permit is required under the city's general building-permit rule, Sec. 5-201.
(a)There is hereby adopted for the city the International Plumbing Code, 2021 edition, as adopted by the South Carolina Building Code Council, published by the International Code Council, Inc., which code is published separately in book form and is adopted by reference as though copied fully in this section. Specifically excluded from the adoption of the International Code referenced herein is Section 103 and its subsections (enumerated as Sections 103.1, 103.2 and 103.3) and 104.8. ... A file of record of this code is in the offices of the city clerk and building official.(b)In the event of any conflict between the provisions of the code adopted by this section and state law or city ordinances, rules or regulations, then the code adopted by this section shall prevail and be controlling unless the code is specifically amended by state law which shall prevail and be controlling.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 35).
Full Breakdown
Sec. 5-91(a) adopts 'for the city the International Plumbing Code, 2021 edition, as adopted by the South Carolina Building Code Council,' incorporating the published code by reference as though copied in full. 8, from the adoption, along with any other provision touching the qualification, removal, dismissal or duties of the building official or other city staff; those matters are governed locally instead. A copy of the adopted code is on file with the city clerk and the building official. Sec. 5-91(b) makes the adopted plumbing code control over any conflicting state law or city ordinance, rule or regulation, unless a later state law amendment overrides it.
Plumbing work itself needs a permit under the general building-permit rule at Sec. 5-201, which requires anyone engaging in any part of the building business in the city, including plumbing, to obtain the appropriate permit and pay the applicable fee before starting. Fees are calculated under Sec. 00 above that, though Sec. 5-204(a)(1) waives a separate trade fee when a licensed general contractor pulls the building permit and lists properly licensed, city-qualified plumbing subcontractors on the application.
Violations & Fines
Starting plumbing work before the permit issues triggers a 100 percent penalty on top of the required fee under Sec. 5-204(c). Working without any permit, or misrepresenting a license to obtain one under Sec. 5-203, exposes the contractor to the city's general Sec. 1-5 penalty of up to $500.00 or 30 days in jail per offense, and repeated reinspection failures add $30.00 for the first reinspection and $50.00 for each one after.
