Oregon splits contractor licensing across two separate agencies, and knowing which one covers which trade matters for understanding what a license actually means. The Building Codes Division (BCD) issues real, business-level licenses for electrical work ('C-Electrical Contractor') and plumbing work ('PB-Plumbing Contractor') — genuine tested credentials tied to the business.
HVAC works differently in Oregon: there is no business-level HVAC contractor license at all. The only HVAC-specific credential Oregon issues (LHR) is an individual-level certification, not something that attaches to a business the way an electrical or plumbing license does. Businesses doing HVAC work in Oregon are typically identified through the Construction Contractors Board's (CCB) general contractor registration, filtered to HVAC-related business names — a general registration, not a trade-tested license.
Roofing and general contracting work similarly: CCB's general registration covers this work too, again without a trade-specific exam behind it the way electrical and plumbing licensing works through BCD. This is why Oregon electrical and plumbing listings on this site are tagged 'Licensed,' while Oregon HVAC and roofing listings are tagged 'Registered' — the underlying credentials are genuinely different in what they verify, and this site's labeling reflects that difference rather than treating all four trades the same.
CCB's general registration data is published as a live, publicly accessible export covering HVAC and roofing/general contractors. BCD's electrical and plumbing license data has a confirmed real record layout, though this site's ingestion for that portion has had some access limitations worth being transparent about — if an Oregon electrical or plumbing listing looks incomplete, it reflects a data access constraint on BCD's side, not a licensing problem with the business itself.
To verify any Oregon contractor directly, both CCB and BCD maintain their own license lookup tools — CCB for general/HVAC/roofing registrations, BCD for electrical and plumbing licenses specifically. Checking the right one matters, since a CCB lookup won't show BCD-issued credentials and vice versa.
For HVAC or roofing work specifically, given that no trade-specific state exam exists behind those categories in Oregon, it's worth leaning more heavily on references, past project photos, and manufacturer certifications (many HVAC manufacturers run their own installer certification programs) as additional signals beyond the state registration alone.
