When you need a mechanical permit

You need a commercial mechanical permit to:

  • New installations, additions, or alterations to mechanical systems.
  • Not all installations require mechanical plans, but all must conform to the Oregon Mechanical Specialty Code.
  • Examples include
    • Rooftop mechanical units
    • Natural gas lines
    • Walk-in coolers
    • Ducting or hood ventilation systems

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.
