Yes, many plumbing jobs in El Dorado County need a permit, and the common ones are water-heater replacement, repiping, gas piping, new or relocated drain and sewer lines, and remodels that move fixtures. Simple repairs like replacing a faucet, a toilet flapper or a supply line generally do not. The permit triggers an inspection, and the inspection is what protects you.
Permit rules are set locally and can change, so treat this article as a practical guide rather than the final word. Unincorporated areas, including El Dorado Hills and Cameron Park, are handled by the county, while the City of Placerville has its own building department. Before any significant job, confirm the current requirements with the El Dorado County building division or ask your licensed plumber to confirm them for you.
Which plumbing jobs usually need a permit
The general principle is that work affecting the safety or the structure of your plumbing system gets permitted, while like-for-like maintenance usually does not. Here is how that sorts out in practice.
- Water-heater replacement. Tank and tankless replacements are typically permitted, partly because of gas connections, venting, seismic strapping, and the temperature-and-pressure relief discharge.
- Whole-house repiping. Replacing the supply piping throughout a home is a major system change and is normally permitted and inspected.
- Gas piping. New gas lines, extensions for a range, dryer, outdoor kitchen or fire feature, and many appliance changes need a permit and a pressure test.
- Sewer and underground work. Replacing or rerouting drain, waste, vent or sewer-lateral piping is typically permitted, especially when trenching is involved.
- Remodels. Moving a sink, adding a bathroom, or relocating a laundry changes the rough plumbing and is usually part of the remodel permit.
- Typically no permit: swapping a faucet, replacing a toilet in the same location, clearing a clog, or replacing a supply line or shutoff valve.
What the rough and final inspections check
Permitted plumbing work usually passes through two inspection stages. The first is the rough inspection, done while pipes are still exposed. The inspector looks at pipe materials and sizing, support and slope on drain lines, venting, and a pressure or leak test on new piping. Nothing gets closed up behind drywall, flooring or a slab until the rough inspection is signed off.
The final inspection happens when fixtures and appliances are connected and the system is working. On a water-heater job, that typically means checking the relief valve and its discharge, the gas connection and venting, the strapping, and the shutoff access. The final sign-off closes out the permit and gives you a record of compliant work.
Permit and inspection timelines vary by project and by the county's workload, so build some slack into your schedule. A water-heater swap is often inspected quickly, while a repipe or underground sewer job may involve more than one visit. Ask your plumber how inspections will be scheduled so you are not left without hot water or a working bathroom longer than necessary.
Having that record matters later. When you sell a home, a buyer's agent or insurer may ask whether major plumbing work was permitted, and an open or missing permit can slow a sale. If you are buying a house, our home-buying plumbing checklist explains what to look for.
Who pulls the permit, you or the plumber
On most jobs, the licensed plumbing contractor pulls the permit, schedules the inspections and is responsible for passing them. Permit cost and inspection scheduling are normally included in the contractor's written estimate, but you should confirm that in writing. A contractor who tells you a permit-required job does not need one, or asks you to pull it under your own name, is a red flag.
California does allow homeowners to pull their own permits as owner-builders for work on their own residence. That means you take responsibility for the work and the inspections, and the work generally must be done by you rather than hired out under your permit. For anything involving gas, hidden piping, or a water heater, a licensed C-36 plumber is the safer path, and California requires a licensed contractor for essentially all plumbing work for hire beyond very minor repairs.

Where EID fits in
The El Dorado Irrigation District supplies water and wastewater service to much of El Dorado Hills, so it is the agency to contact for questions about your water service, your meter and connection, and the public side of the sewer. County permits and EID services are separate. A building permit for work inside the house does not replace any coordination EID may require for the service connection or the lateral that ties into its system.
If your job touches the water meter, the service line between the meter and the house, or the connection to the sewer main, mention it at the start. We coordinate with EID where the work calls for it so the permit, the inspection and any district requirements line up instead of tripping over each other.
