Summary
Vacaville enforces the 2025 California Plumbing Code, based on the 2024 Uniform Plumbing Code, as the governing standard for all plumbing work under Municipal Code Section 15.20.254.010. The city's building division holds delegated enforcement authority under CCR Title 24, Part 5, so plumbing installation, repair, or alteration needs a permit and inspection first.
Adopt the California Plumbing Code (CPC) and appendices, 2025 Edition, Chapter 1, Division II and the appendices thereto, based on the 2024 Uniform Plumbing Code as published by the International Association of Plumbing and Mechanical Officials and as adopted by the California Building Standards Commission, the Department of Housing and Community Development, and other agencies listed in Chapter 1, where the City is the enforcing authority or the authority has been delegated to the City by these agencies in California Code of Regulations, Title 24, Part 5.
Full Breakdown
The city adopted the CPC, 2025 Edition, Chapter 1, Division II, and its appendices by ordinance under Section 15.20.254.010, incorporating amendments made by the California Building Standards Commission and the Department of Housing and Community Development. Where the state has delegated enforcement to local government, Vacaville's building division is the authority that reviews plumbing plans, issues permits, and performs inspections.
Permit disputes are not left to informal resolution. Section 15.20.250.100 amends CPC Section 107.0 to add subsection 107.3, routing appeals to the same building appeals board created for the California Building Code: five members of the Napa-Solano Chapter of the International Code Council, chosen case by case by the Building Official, with at least two CASp-certified members required for disabled-access appeals. The Chief Building Official sits as a non-voting, ex-officio member.
Enforcement runs through the general penalty and violations provisions that apply across Title 15. Section 15.20.250.101 makes each day a plumbing violation continues a separate offense, punishable as a misdemeanor under Chapter 1.16 and subject to administrative fines under Chapter 8.10, and treats the violation as a public nuisance subject to abatement.
Violations & Fines
Working without a plumbing permit, or continuing work after a stop-work order, is a misdemeanor under Section 15.20.250.101, with each day of violation charged as a separate offense. The city can also issue administrative fines under Chapter 8.10 and pursue the matter as a public nuisance. Permit denials or code interpretations can be appealed to the Napa-Solano ICC building appeals board.
