Iowa Contractor & Trade License Requirements
Iowa requires statewide licensing for electricians, plumbers, and HVAC/mechanical contractors. The Electrical Examining Board licenses electricians, while the Plumbing and Mechanical Systems Board (PMSB) licenses plumbers, HVAC technicians, and mechanical contractors. General contractors and roofers do not need a state license but must register with the Iowa Division of Labor if earning $2,000 or more annually from construction work.
