Summary
Sioux Falls has adopted the 2024 Uniform Plumbing Code, and a permit from building services is required before any plumbing system work begins.
The Uniform Plumbing Code, 2024 edition, including Appendix A—Recommended Rules for Sizing the Water Supply System ... and Appendix R—Tiny Houses, are hereby adopted by the city for regulating and controlling design, construction, quality of materials, erection, installation, alteration, repair, location, relocation, replacement, addition to, use, or maintenance of any plumbing and providing for the performance of inspections and collection of fees therefor.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: 2026 S-135: Current through local ordinance 54-26, passed 7-14-2026).
Full Breakdown
The city adopted the 2024 Uniform Plumbing Code to govern design, installation, alteration, repair, and maintenance of plumbing, with inspections and fees required (§ 150.301). Separately, the city's building permit rule (§ 150.002, adopting IRC § R105.1 as amended) requires an owner or authorized agent to apply for and obtain a permit before installing, altering, repairing, removing, converting, or replacing any plumbing system. Only licensed or owner-installers may pull the permit; building services enforces both chapters.
Violations & Fines
Starting plumbing work before the permit issues triggers an added fee on top of the permit fee, plus possible administrative citations and civil or legal proceedings (§ 150.002, IRC § R108.6). Other violations of the plumbing chapter default to the general penalty in § 10.999.
