Plumbing permits and inspections in Orange County
Which plumbing jobs usually need a permit, who pulls it, what an inspector looks at, what happens when work goes unpermitted, and how Done-Rite handles the whole process.
A permit is not paperwork for its own sake. It is the record that the work on a water heater, sewer line, gas line or repipe was inspected by the city. When a job needs one, Done-Rite pulls it. These pages explain the general rules and point you to the building department that has the final say for your address.

Do you need a permit to replace a water heater?
Usually, yes. Replacing a tank water heater or installing a tankless unit is permitted work in most of Orange County, because the job touches gas, venting and pressure relief. Done-Rite pulls the permit when one is required.

Do you need a permit for sewer line repair or replacement?
Cleaning a sewer line, jetting it or putting a camera down it needs no permit. Replacing it, lining it or bursting it does, because the work changes the lateral that connects your house to the public sewer. Done-Rite pulls it.

Do you need a permit for a gas line?
Usually, yes. Running a new gas line, extending one for a new appliance, or repairing a section usually needs a permit, and the inspection typically includes a pressure test. Done-Rite pulls the permit when one is required.

Do you need a permit for a whole-house repipe?
Yes. A whole-house repipe replaces the water piping to every fixture, and it is permitted and inspected work in Orange County. Done-Rite pulls the permit and schedules the inspections as part of the job.

What a plumbing inspector checks, and what happens if something fails
A plumbing inspection is the building department's check that permitted work matches the adopted code before it is closed in or put in service. A fail means a correction and a re-inspection, not a penalty.

What happens if plumbing work is not permitted or not up to code
Unpermitted plumbing work does not usually fail immediately. The exposure shows up later: a resale inspection that flags it, an insurance claim that asks for the record, or a venting or gas mistake nobody caught.
