Summary
Rancho Cucamonga has adopted the 2025 California Plumbing Code, based on the Uniform Plumbing Code, by reference for all plumbing work in the city. Permit fees are set by City Council resolution rather than the code's own fee tables, which the city deleted outright.
104.5 Fees. The fee for each permit shall be as established by Resolution of the City Council. ... Table 104.5 is hereby deleted. ... The 2025 California Plumbing Code, incorporating the "Uniform Plumbing Code," 2024 Edition, including all appendices thereto ... are hereby adopted by reference in their entirety and amended in Chapters 15.04, 15.12, 15.14, 15.16, 15.20, 15.24, 15.26, 15.28, 15.30, 15.32, and 15.34 herein, shall comprise the Building and Construction Regulations of the City of Rancho Cucamonga.
Full Breakdown
20. Anyone performing plumbing work covered by the code must obtain a plumbing permit under that adopted code as locally amended. 5 of the Plumbing Code outright, meaning the state's default fee schedule does not apply here; applicants must instead consult the council-adopted fee resolution for current plumbing permit costs. 1: the Board has three members and two alternates, none of whom may be city employees, and the Building Official sits as a non-voting ex officio secretary. The Board must adopt its own procedural rules and issue written decisions with a duplicate sent to the Building Official.
050 adds a local technical requirement for copper tubing serving kitchen island fixtures under concrete slabs, requiring installation in a capped, watertight continuous sleeve until the work is inspected. These amendments were most recently updated by Ordinance No. 1048, effective November 19, 2025.
Violations & Fines
Plumbing work performed without the required permit, or that fails to meet the locally amended standards such as the under-slab kitchen island sleeve requirement, is enforced by the Building and Safety Department, which can red-tag work and require it be exposed for inspection or corrected before occupancy sign-off. Appeals of a Building Official's plumbing permit determination must go to the three-member Board of Appeals created under Section 15.20.010.
