Appliance Repair

Oklahoma does not license general appliance repair at the state level. No state license or insurance requirement applies unless the work crosses into a regulated trade (HVAC/mechanical, electrical, or gas piping), which requires CIB licensure. Manufacturers' warranty networks, home warranty companies, and commercial landlords typically require proof of general liability insurance (COI) regardless.

Workers' Compensation Threshold

Oklahoma requires employers with one or more employees to secure workers' compensation coverage, but sole proprietors, partners, and 10%+ owner-members are not required to cover themselves, and businesses with five or fewer employees who are all related within the second degree to the owner are exempt.
