Trade business resources for Iowa.

Iowa does not have a single statewide general contractor licensing board; instead, licensing and registration requirements vary by trade and are administered by different state agencies. Electricians, plumbers, and HVAC mechanics are licensed at the state level through the Iowa Division of Labor, while general contractors are not required to hold a statewide license but must register with local jurisdictions and meet bonding/insurance requirements.

State licensing board

In Iowa, electrical contractors and journeyman/master electricians are licensed through the Iowa Division of Labor's Electrical Examining Board, with licenses required for virtually all electrical work. Plumbers must hold a state license (apprentice, journeyman, or master) issued through the Iowa Division of Labor's Plumbing and Mechanical Systems Board, which also oversees mechanical (HVAC) contractors requiring a master mechanic license for HVAC work. General contractors have no mandatory statewide license, but many cities and counties require local registration or permits, and contractors working on public projects must meet bonding thresholds. Roofers are not licensed at the state level in Iowa, though some municipalities impose local registration requirements. Any contractor performing work valued over $2,000 on residential property may be subject to Iowa Home Inspector and contractor consumer protection statutes, and all businesses must register their entity with the Iowa Secretary of State.
