Fresno, CA Building Safety: Plumbing Permits (2026)

Section 11-107 of the Fresno Municipal Code adopts the California Plumbing Code, 2025 Edition, itself built on the 2024 Uniform Plumbing Code with California amendments, and incorporates it by reference into the Fresno Building Code. Anyone doing plumbing work covered by the CPC, from water heater swaps to full repipes, works under this adopted code, and Chapter 1 of the Fresno Building Code (not Chapter 1 of the CPC alone) governs the administrative side: permit applications, plan review, and inspections through the Planning and Development Department's Building and Safety Services Division, where a physical copy of the code is kept on file for public review.

1, galvanized malleable iron, galvanized wrought iron, and galvanized steel are outright prohibited for building water piping and building supply piping, both underground and inside structures, a stricter local rule than the base state code contains. 8, which let a local agency impose more restrictive plumbing standards than the state model code. Work performed without the required permit, or using a prohibited material, is enforced as a Municipal Code violation rather than left to voluntary compliance, since the CPC is expressly folded into the enforceable Fresno Building Code framework.
