Trade business resources for Oklahoma.

In Oklahoma, trade contractors must be licensed through the Construction Industries Board (CIB), which oversees licensing for electrical, plumbing, HVAC, and other construction trades. Licensing is required at both the contractor (business) and journeyman/apprentice (individual) levels for most mechanical trades.

State licensing board

Oklahoma's Construction Industries Board licenses electrical contractors and journeymen, plumbing contractors and journeymen, and HVAC/mechanical contractors and journeymen — all requiring separate examinations and proof of experience regardless of project dollar amount, as these trades are regulated by trade type rather than a single dollar threshold. General contractors in Oklahoma are not licensed at the state level for most residential and commercial work; instead, GC oversight is primarily handled at the local/municipal level, though public construction projects may require additional bonding or registration. Roofing contractors are required to register with the CIB (a registration rather than a full license), and any roofing work performed for compensation triggers this requirement. Specialty and subcontractor categories such as fire suppression and manufactured housing also fall under CIB jurisdiction. All licensees must carry general liability insurance and, in most cases, a surety bond to obtain and maintain their license.
