Violations & Fines
Section 15.20.060 sends plumbing-code violations through Chapters 15.02 and 15.70: absent a different penalty for a specific provision, a violation is an infraction, but anyone convicted twice or more within a rolling 12-month period is guilty of a misdemeanor, and each day a violation continues is a separate offense. Working without a required permit or violating a posted stop-work order can also trigger misdemeanor exposure under the adopted California Building Code.
