Full Breakdown

Ordinance No. 070 adopts by reference the 2025 California Plumbing Code (CPC) as the plumbing code of the City of Rialto. 8 to require an earthquake-actuated gas shutoff valve on every new structure, expressly naming residential, commercial and industrial buildings. The valve must be designed to automatically shut off gas at the valve's location when a seismic disturbance occurs, and it must be certified by the State Architect as conforming to the California Code of Regulations, Title 24, Part 12, Chapter 12-16-1. This is the only local amendment Rialto made to the 2025 CPC; every other plumbing standard follows the statewide code text unchanged.

070. 5 bars occupying a building until the Building Official has issued the permit, completed inspections, and issued a certificate of occupancy. 7 lets the Building Official assess a reinspection fee if plumbing work is not ready when an inspection is called or required corrections have not been made, and repeat reinspection fees apply once approved plans are not available on-site or access is denied on the scheduled date.

Installing or altering plumbing systems, including gas piping, without the required permit exposes the responsible party to prosecution under Chapter 1.16 of the Rialto Municipal Code. A misdemeanor conviction is punishable by a fine of up to $1,000, imprisonment of up to six months, or both, while an infraction escalates from a $100 fine on a first violation to $200 on a second within two years and $500 on each additional violation, with each day of an ongoing violation charged separately.

Frequently Asked Questions

Did Rialto make other changes to the state plumbing code?

Yes. The administrative permit requirement adopted at RMC 15.08.030[A], amending CBC Section 105.1, applies to every chapter of Rialto's building codes including 15.08.070, so plumbing installations, alterations and repairs all require a permit from the Building Official before work begins.
