Plumbing inspection
The site visit by the AHJ's inspector that verifies permitted work matches the adopted code before it is closed in or put into service. A failed inspection means a correction and a re-inspection, not a fine.
What does the inspector look at?
It depends on the job: connections, venting, bracing and the relief valve drain on a water heater; slope, bedding and material on a sewer line; pressure test results on gas piping. The checklist is the AHJ's, so confirm specifics with the building department.
//At Done-Rite
In Done-Rite's field experience, the most common thing an Orange County inspector flags on a permitted job is a missing carbon monoxide alarm, so the crew checks for one before scheduling the inspection. That is field experience, not a statement of what the code requires; the California Residential Code (R315.2.2) exempts plumbing installation, alteration and repair from the CO alarm trigger.
