When does a bathroom remodel need a permit in Woodinville?
In Woodinville, tile, paint, cabinets, countertops and similar finish work need no building permit (WMC 21.62.070 item 6). The City leaves the state plumbing code's exemptions unchanged, so replacing a toilet, sink, tub, shower or faucet, even in the same spot, moving or adding plumbing, or replacing a defective trap or drain pipe needs a plumbing permit; replacing a single-family fixture is issued over the counter in the City's Permit Portal, with no plan review. Moving a wall or other structural work needs a building permit, which then covers the plumbing. New or moved circuits need an electrical permit from L&I: the City issues none.
