  • A plumbing business in Oregon holds two licenses from two agencies. The Building Codes Division issues the plumbing business license for $150. The Construction Contractors Board issues the contractor license for $400. You need both before you take a job.
  • Oregon has no sales tax at all. You never add tax to a bill and never pay it on pipe, fittings or fixtures.

  • Oregon has no HVAC license of its own. The business runs on a CCB contractor license, and the trade cards that matter are electrical ones from the Building Codes Division.
  • A service business that only fixes commercial equipment can hold the Limited Maintenance Specialty Contractor HVAC/R license for $75, which buys three years. It stops at the disconnect switch and never covers a new install.

  • An electrical business cannot open without a general supervising electrician on the payroll full time. That person needs 8,000 hours as a journeyman first, so the path from apprentice to owner is eight years.
  • The trade license and the business license come from different agencies. The Building Codes Division charges $375 for a three-year electrical contractor license, and the Construction Contractors Board charges $400 for two years on top.
