Summary
Yavapai County Ordinance No. 2025-3 amends Section 101.4.3 of the adopted building code to apply the 2024 International Plumbing Code to every plumbing installation, alteration, repair and replacement in the unincorporated county, covering fixtures, appliances, water and sewage connections and medical gas systems. Septic and other sewage-disposal systems are carved out to Yavapai County Environmental Services or other jurisdictions with authority.
[A] 101.4.3: Plumbing. The provisions of the 2024 Edition of the International Plumbing Code, as amended and adopted by Yavapai County, shall apply to the installation, alteration, repair and replacement of plumbing systems, including equipment, appliances, fixtures, fittings and appurtenances, and where connected to a water or sewage system and all aspects of a medical gas system. The provisions for sewage disposal systems shall be regulated by the Yavapai County Environmental Services and/or other jurisdictions having authority.
Full Breakdown
Effective January 1, 2026, Ordinance No. 2025-3 repealed the county's prior building code in its entirety and readopted the International Building Code, 2024 Edition, with local administrative amendments for unincorporated Yavapai County. 3, Plumbing, is the one that actually pulls in the 2024 International Plumbing Code and applies it to the installation, alteration, repair and replacement of plumbing systems, including equipment, appliances, fixtures, fittings, appurtenances connected to a water or sewage system, and all aspects of a medical gas system. The same section expressly routes sewage disposal systems, meaning septic tanks and leach fields common on the county's large rural parcels, to Yavapai County Environmental Services or whichever other jurisdiction has authority, rather than to the Building Safety Unit.
1, whose building official administers and enforces every referenced code. Section 105, Permits, deletes the annual-permit and annual-permit-records options the base IPC allows, meaning each plumbing job in unincorporated Yavapai County needs its own individual permit rather than a blanket annual one. The companion Ordinance No. 2025-5 adopts the 2024 International Plumbing Code text itself as a standalone document for the county, alongside the 2024 IBC (2025-3), the 2024 International Residential Code (2025-4), the 2024 International Mechanical Code (2025-6), and the 2024 International Fuel Gas Code (2025-7), all effective the same January 1, 2026 date.
Violations & Fines
Installing, altering or replacing plumbing systems without the required permit puts the work outside the International Plumbing Code framework Yavapai County Development Services enforces, and the Building Safety Unit's building official can require correction, halt work, or deny final inspection and occupancy sign-off until the permitted plumbing is brought into compliance under the adopted 2024 IPC amendments.
