Summary
Downey requires plumbing work to comply with the California Plumbing Code, 2025 Edition, which the city adopted wholesale as the Downey Plumbing Code under Municipal Code § 8301, along with Appendices B, C, D, and K. The Building and Safety Division administers plumbing permits and inspections under this adopted code, keeping a copy on file for public review.
That certain document, one copy of which is on file in the Building and Safety Division and the office of the City Clerk, entitled California Plumbing Code, 2025 Edition, published by the California Building Standards Commission (California Code of Regulations Title 24, Part 5) and Appendices B, C, D, and K of that same Code, are hereby adopted by reference, as part of this chapter as though fully set forth herein. ... § 1200. VIOLATIONS, PENALTIES. ... (c) Every offense that is prosecuted as a misdemeanor, the penalty for which is not otherwise prescribed by ordinance or in this Code, shall be punishable by a fine of not more than $1,000 or by imprisonment in the City or County jail for not more than six months, or by both such fine and imprisonment.
Full Breakdown
Downey doesn't write its own plumbing rules from scratch: § 8301 adopts, "as though fully set forth herein," the entire California Plumbing Code, 2025 Edition, published by the California Building Standards Commission at Title 24, Part 5 of the California Code of Regulations, plus Appendices B, C, D, and K of that code. A copy is kept on file with the Building and Safety Division and the City Clerk for public inspection. This chapter has been updated to track the state's code cycle: originally added by Ordinance 20-1428 on February 11, 2020, amended by Ordinance 22-1494 on November 10, 2022, and again by Ordinance 26-1539 on January 27, 2026, which brought Downey's plumbing rules current with the 2025 state edition.
Because the plumbing code is adopted by reference rather than rewritten locally, its own permit, inspection, and fee provisions govern plumbing work citywide, administered by the Building and Safety Division alongside the parallel Building (Chapter 1), Electrical (Chapter 2), and Mechanical (Chapter 3) codes in Article VIII. Anyone who performs plumbing work without the permit that code requires, or who otherwise violates a condition of an issued permit, is subject to Downey's general code enforcement penalty under § 1200: a misdemeanor punishable by up to a $1,000 fine or six months in jail, unless the City instead charges the violation as an infraction, which carries escalating fines of $100, $200, and $500 for a first, second, and third offense within a year.
Violations & Fines
Performing plumbing work without the required permit, or failing to correct deficiencies flagged during a Building and Safety Division inspection, exposes an owner or contractor to prosecution under § 1200: a misdemeanor carrying up to a $1,000 fine and six months in jail, or, if charged as an infraction, escalating fines of $100 for a first offense, $200 for a second, and $500 for each later violation within a year.
