Permits

Plumbing permits in Walla Walla County: who issues them.

Plumbing permit fees, forms and process

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.
