How to become a general contractor in Iowa
State law and licensing-board sources · Last reviewed October 11, 2026
Journeyman level Licensed by cities or counties, not the state What's a journeyman?
Iowa does not license general contractors at the state level. Instead, state law requires anyone who earns at least $2,000 a year from construction work to register with the Department of Inspections, Appeals, and Licensing (DIAL), which checks workers' compensation and unemployment insurance compliance. There is no exam and no experience requirement for registration. Some cities add their own contractor licenses: Davenport, for example, requires a city license with a passing exam score. Electrical, plumbing and HVAC (heating, ventilation and air conditioning) work need separate state trade licenses. [1][2][3][4]
New to the trade?
Starting from zero in Iowa
Iowa has no state general contractor license, and its contractor registration is for people and businesses in the business of construction. Start by getting hired by a contractor, or find a registered apprenticeship (carpentry is the usual route for general construction) through the Iowa Office of Apprenticeship or your local IowaWORKS office. You need a state contractor registration only when you run your own construction business earning $2,000 or more a year. [1][3][9][10]
High school diploma or GED
Not part of the state's contractor registration, which asks for business, insurance and tax information rather than education. Iowa Workforce Development says requirements for registered apprenticeships vary by career path and each sponsor sets its own Ask the program. [1][2][11]
Minimum age
No age is set in the registration law. Iowa child labor law lets students under 18 in a registered apprenticeship or an approved career and technical education or work-based learning program do some otherwise restricted work, if it is incidental to training, brief and closely supervised, and a parent and the school or employer give written permission. [1][12]
Register before you start work
Registration is for people and businesses engaged in the business of construction that earn at least $2,000 a year from it. If you work for yourself and earn that much, you must register before performing construction work. Subcontractors aren't covered by the general contractor's registration. [1][2][3]
Pay while you learn
Iowa Workforce Development says registered apprentices start working and earning from day one, and in most cases the employer pays for classroom costs. [9][11]
Still in high school?
Iowa Workforce Development says more Iowa high schools offer registered apprenticeship programs, often with the school district as sponsor, plus quality pre-apprenticeship programs Start by talking with your school counselor. Iowa's career and technical education (CTE) programs include an applied sciences, technology, engineering and manufacturing service area that covers architecture and construction, and Senior Year Plus concurrent enrollment and career academies let you take community college career and technical courses while in high school.

Who must register
Iowa's contractor registration law covers anyone in the business of construction, a term defined broadly for unemployment insurance purposes: new work, additions, alterations, repairs and demolition. DIAL says carpenters, electricians, plumbers, roofers, painters and many others must register. You don't have to register if you earn less than $2,000 a year from construction or work only on your own property.
Registration exists so the state can check compliance with workers' compensation and unemployment insurance laws, collect what out-of-state contractors owe, and give the public information about contractors. It is not a test of your skills: there's no exam or experience requirement.
The state can't award a contract to an unregistered contractor. Penalties are up to $500 for a first violation and up to $5,000 for each later one. [1][2][3]
How to register
- Apply online or by mail from DIAL's contractor registration page.
- You need a valid unemployment insurance account number, your NAICS (business activity) code, proof of workers' compensation if you have employees, and the fee.
- Fee: DIAL's pages describe a nonrefundable $50 yearly fee and yearly renewal. The rule sets $50 per year or $150 for a three-year registration.
- Fee exemption: self-employed contractors who don't pay more than $2,000 a year to employ others, don't work with or for other contractors in the same phase of construction, and aren't an LLC (limited liability company), corporation or partnership can file a notarized exemption form instead.
- Out-of-state contractors must file a $25,000 surety bond unless they're prequalified to bid on Iowa DOT projects.

City contractor licenses
Because the state doesn't license general contractors, some cities do. Davenport's city code says no one may engage in construction contracting there without a city license. Licenses go to individuals, who can then get permits and supervise work for a company. General building license candidates need 70% on an exam from the International Code Council or Prometric, a $25,000 surety bond, and a fee of $200 (residential) or $300 (commercial). Contact Davenport Public Works at (563) 326-7745.
Other cities may have their own rules; DIAL tells contractors to contact the city or county government for each project. [3][4]
Electrical, plumbing and HVAC work
Trade work is licensed by the state, not by contractor registration. Electrical contractors need an electrical contractor license from the Electrical Examining Board. Plumbing and mechanical (HVAC) contractors need a Plumbing and Mechanical Systems Board contractor license, which comes with the contractor registration in one joint application, and they must hold or employ a licensed master.
See Iowa electrician, Iowa plumber and Iowa HVAC. [3][6][7][8]
Recent changes
Contractor registration moved to DIAL: the rules that were Labor Services Division chapter 875-150 became DIAL chapter 481-465 as of July 9, 2025, and the law now names DIAL as the department. [1][2]
