These steps are practical suggestions, not BCD rules.

  1. Ask for the business name and the license number in writing.
  2. On the BCD form, choose License Number if you have it; otherwise choose Business Name or Individual Name.
  3. Note whether the record you find is for a business or for an individual.

How does a plumbing business differ from a journeyman plumber in Oregon?

BCD's contractor and business licenses page, read 1 November 2026, describes the plumbing business entry: "(PB) Allows a business to advertise; furnish labor and material, or labor only; install; change; and repair plumbing."

Source: Oregon Building Codes Division, contractor and business licenses, read 1 November 2026.

The same entry goes on: "This registration does not entitle the holder to work as a journeyman plumber without an appropriate individual license."

Source: Oregon Building Codes Division, contractor and business licenses, read 1 November 2026.

BCD's individual licenses page, read 1 November 2026, gives the journeyman scope: "(JP) Scope: Perform all plumbing installation, alterations, or remodels."

Source: Oregon Building Codes Division, individual licenses, read 1 November 2026.

The Oregon Legislature's copy of ORS chapter 693, read 1 November 2026, says in section 693.030: "A person may not engage in the trade of journeyman plumber without a journeyman plumber license issued under this chapter."

Source: ORS 693.030(1), read 1 November 2026.

For apprentices, section 693.040 of the same chapter says: "An apprentice plumber may work at the trade of plumbing if the apprentice works under the supervision of a licensed journeyman plumber."

Which specialty plumber scopes does BCD list?

BCD's individual licenses page, read 1 November 2026, describes the water-treatment installer: "(WTI) Scope: Make connections to potable water systems and indirect waste connections to existing drain waste and vent systems."

Source: Oregon Building Codes Division, individual licenses, read 1 November 2026.

The same page describes the residential water-heater installer: "(WHI) Scope: Replace existing water heaters in one- and two-family dwellings."

Source: Oregon Building Codes Division, individual licenses, read 1 November 2026.

Section 693.103 of the Oregon Legislature's copy of ORS chapter 693, read 1 November 2026, says: "A limited specialty plumber license authorizes a person to perform work in the specific branch of the plumbing trade for which the license is issued."

Source: ORS 693.103(2), read 1 November 2026.

Our suggestion is to compare the scope on the record with the work in the bid, such as a water-heater swap or a wider remodel.

Where do you send a concern about plumbing work in Oregon?

The same page gives a different route for permits: "Consumers should report businesses or trade workers that fail to obtain the necessary permits to their local building department, unless there are more alleged violations; in that case, file a complaint with the Building Codes Division."
