Who issues the permit depends on your address
Oregon building permits are issued by whichever jurisdiction you live in, not by the state. In our area that means:
- Inside Medford city limits — the City of Medford Building Safety division.
- Ashland — the City of Ashland issues its own.
- Central Point, Eagle Point, Talent, Phoenix, Jacksonville, Rogue River, Gold Hill, Shady Cove — mostly through Jackson County Development Services, though a few cities contract differently; the county's office will tell you in one phone call.
- Unincorporated Jackson County (White City, the Applegate, rural addresses) — Jackson County Development Services.
- Grants Pass and Josephine County — the City of Grants Pass or Josephine County, respectively.
The county's building page is jacksoncountyor.gov → Development Services → Building. A licensed contractor pulls the permit in the contractor's name; you don't have to do any of this yourself.
What usually needs a permit
- Plumbing permit — any time a drain, vent, or supply line is moved, added, or replaced. A tub-to-shower conversion changes the drain and the valve, so it needs one. Replacing a shower valve behind the wall generally does too.
- Electrical permit — a new circuit, a new outlet or GFCI location, a heated floor, a fan on a new switch, most new lighting runs.
- Building (structural) permit — moving or removing a wall, widening a doorway through a bearing wall, changing a window, or lowering a floor for a curbless shower in some cases.
- Mechanical permit — a new bath fan that vents outside (which it should — venting into the attic is how you grow mold).
What usually doesn't
- Replacing a vanity, sink, faucet, or toilet in the same spot (like-for-like).
- Paint, mirrors, towel bars, medicine cabinets.
- Replacing flooring, as long as nothing structural changes.
- Installing grab bars into existing walls.
Oregon's plumbing rules do exempt some simple fixture replacements, but the line between "replacement" and "alteration" is thinner than people think. When in doubt, we ask the county — it's a five-minute call and it costs nothing.
Why you want the permit even when nobody would notice
Three practical reasons, none of them about following rules for their own sake:
- Insurance. If an unpermitted plumbing change leaks into the floor below, a claims adjuster will ask for the permit. Not having one is an easy reason to deny the claim.
- Resale. Buyers' inspectors and title companies in Jackson County look for open or missing permits. Unpermitted bathroom work is one of the most common things that stalls a closing in Medford.
- A second set of eyes. The inspector checks the waterproofing pan and the drain before we tile over it. That's a free inspection of the part you'll never see again.
What it costs and how long it adds
Permit fees for a typical bathroom remodel in Jackson County run from a few hundred dollars for plumbing-plus-electrical up to more when structural work is involved; the exact schedule is on the county's site and it changes yearly, so we quote it per job rather than guessing here. Our prices include the permit and the inspections. Timeline-wise, inspections happen at rough-in and at final; on a one-week conversion they add zero days because we schedule them around the work.
What the permit is not is a reason to pick a contractor who says you don't need one. That's a red flag, and it's usually a sign the plumbing work is being done by someone who isn't licensed to do it.
