Who can do commercial mechanical work
If the work proposed is in a building that is not intended for rent, sale, lease or exchange, the property owner, an owner’s representative, or the tenant can perform the work, as well as an Oregon-licensed general contractor.
All contractors working in the State of Oregon must have a license to work in Oregon. The Oregon Construction Contractors Board (CCB) ↗ issues licenses to contractors and maintains records on licensed contractors and any claims filed against them. Contact the CCB at (503) 378-4621 for further questions.
