Do you need a license to work as a plumber in Oregon?
Yes. In Oregon, a person must hold a plumbing contractor license to work or advertise as a plumbing contractor, and a journeyman plumber license from the State Plumbing Board to work in the trade of journeyman plumber. A plumbing contractor license does not authorize the contractor to work as a journeyman plumber. The plumbing contractor licensing law does not apply to a person doing plumbing work when not engaged for hire, or using regular employees for plumbing work on property the person owns, leases or operates. This is ORS 447.040, 447.060, 693.030, 693.060.
