Permits

Plumbing permits in Benton County: who issues them.

Plumbing permit fees, forms and process

Plumbing permits and inspections in Washington come from the city or county building department with jurisdiction, under the Uniform Plumbing Code the state adopts for everyone. The work itself must be done by an L&I-licensed plumbing contractor employing certified plumbers (RCW 18.106.020), with one exception the statute spells out: a person may do plumbing work at their own residence, farm, place of business or other property they own (RCW 18.106.150).

Permit guides here are written per city, because that is who issues them.
