Shasta County, CA Building Safety: Plumbing Permits (2026)

10's plumbing rule sits inside the same wildfire-rebuild pilot program that lets owner-built rural dwellings skip a wired electrical hookup: it applies to Limited Density Owner-Built Rural Dwellings permitted after the Carr (2018), Zogg (2020), Salt (2021), and Fawn (2021) wildfires. 360's plumbing-code adoption. The type, design, and number of sanitation facilities must appear on the plans submitted with the building permit application. No dwelling built under this chapter may discharge wastewater from a sanitary facility anywhere except into a wastewater system designed, constructed, operated, and maintained to the standards of the resource management department's environmental health division, and no dwelling may use a bathtub or shower alongside a washbasin, or any alternate bathing and washing setup, unless the environmental health division and the building official have both approved it first.

170, issued separately from the structure's building permit, and no permit is issued for a system serving a new use unless it is coordinated with that use's building or mobile home permit.
