Full Breakdown
010 adopts the California Plumbing Code, 2025 Edition, together with appendices A, B, D, G, L, R, and S, as the plumbing code for the City of Vallejo, incorporating it by reference save and except such portions as are deleted, modified, or amended. The base text is the 2024 International Plumbing Code as amended by the state and published in the 2025 California Building Standards Code at Title 24, Part 5, of the California Code of Regulations. Because the code is adopted in full, its permit provisions control when Vallejo property owners and licensed plumbers must obtain a plumbing permit before starting work, covering new water supply and drain-waste-vent installations, water heater replacements, sewer lateral repairs, and fixture additions or relocations. 010 requires. 020. Ordinance No. (2d), adopted November 25, 2025, most recently repealed and reenacted this chapter to update it to the 2025 edition.
Violations & Fines
Plumbing installed without a required permit, or that departs from the adopted 2025 California Plumbing Code, is subject to the same Title 12 enforcement tools as any other building-code violation: the building official can red-tag the work, order it stopped, and pursue the code's penalty provisions for unpermitted or noncompliant installations. Because the code is adopted save and except portions deleted, modified, or amended, any Vallejo-specific amendment on file with the building official governs over the unmodified state text.
