Yucaipa, CA Building Safety: Plumbing Permits (2026)

Section 15.04.035 adopts the California Plumbing Code, 2025 Edition (Part 5, Title 24, California Code of Regulations), including all appendices, as the Plumbing Code of the City of Yucaipa. It incorporates and amends the Uniform Plumbing Code, 2024 Edition, published by the International Association of Plumbing and Mechanical Officials, and adopts the IAPMO Installations Standards, 2024 Edition. The code covers design, installation, alteration, repair, replacement and maintenance of plumbing systems in the City of Yucaipa, with permits and fee collection, and a copy is kept at the Building Division of the Development Services Department for public inspection.

Two local amendments apply. Section 710.1 requires an approved backwater valve on drainage piping that serves fixtures with flood level rims located less than 12 inches above the elevation of the next upstream manhole cover of the public sewer. Fixtures served by a private sewage disposal can have their flood level rims at the elevation of that manhole cover, but fixtures above that elevation cannot discharge through the backwater valve. Backwater valves are prohibited on garage floors. Section 719.1 puts cleanouts inside the building near the connection between the building drain and the building sewer, or outside the building at the lower end of the building drain and extended to grade, and prohibits cleanouts on garage floors.

Permit administration comes from § 15.04.015. Section 109.2 sends plumbing permit fees to the most recent City Council resolution, and the plan review fee is due when plans are submitted. A residential permit becomes invalid unless work starts within 365 days of issuance, or if work is suspended or abandoned for 180 days between required inspections, and the Building Official can grant one written 180-day extension. A re-inspection fee under Section 109.8 can be imposed when the work called for inspection is not complete, though not the first time a job is rejected. The City Council serves as the board of appeals.
