Oklahoma either licenses or registers its electrical, plumbing, roofing, and mechanical contractors. All contracting companies should also be properly registered and have a business license. General contractors do not require a state-wide license, although they should hold the appropriate liability insurance and Worker’s Comp insurance, if applicable.
Becoming a Contractor in Oklahoma
All contractors in Oklahoma should be properly trained and experienced before venturing out on their own. This experience is often gained through a 4-year apprenticeship, college trade program, or by working under a licensed contractor.
Electrical, mechanical, plumbing, and roofing contractors will also need to take and pass an official exam, complete an application, and pay a fee for a state license. All verifiable work experience for these licenses must be completed as a registered apprentice and/or under a licensed contractor in their field.
General contractors will need to adhere to their city’s regulations, which often include liability insurance, Worker’s Comp, and other tax requirements.
