Full Breakdown
8, with one true copy kept on file with the Building Official for public inspection. 4 now requires every new single-family and multi-family building's water distribution system to include a water softener loop within 6 feet of the building drainage system access point. 3 requires copper or copper alloy water piping to be at least Type L weight. 4 lets a property owner replace a failing private sewage disposal system instead of connecting to the public sewer if connection would cost more than 150 percent of the private system's approved replacement cost.
1 puts every grease interceptor system under review, approval and inspection by the city's sewer authority, currently Ventura Water, in addition to the Building and Safety Division's plumbing review, with the Division coordinating between the two. Appendix H's private sewage disposal rules add that soils reports must be supervised by a licensed Environmental Health Specialist, Civil Engineer, Geologist, or Engineering Geologist, and that industrial waste discharge into a soil absorption system is prohibited unless the Local Appeals Board reviews and approves it. Appeals of any Building Official plumbing decision run through CBC Section 113, meaning the City Council itself sits as the Local Housing Appeals Board.
Violations & Fines
Plumbing work performed without the required permit, or a grease interceptor installed without Ventura Water's review and inspection, is a code violation the Building Official enforces through the standard Notice of Non-Compliance process recorded against the property. Discharging industrial waste into a soil absorption system without Local Appeals Board approval is expressly prohibited under Appendix H, Section H901.6.
