Which Iowa Trades Require State Registration

Iowa requires registration for all construction contractors under Iowa Code Chapter 91C. This covers general contractors, subcontractors, and specialty contractors performing any type of construction work including new construction, remodeling, roofing, framing, painting, concrete, siding, electrical, plumbing, and HVAC.

Each registration includes a NAICS activity code describing the contractor's primary work type — such as new single-family housing construction, roofing contractors, framing contractors, electrical contractors, plumbing and HVAC contractors, and more.

Contractors must display their registration number on all vehicles used in the business and on contracts. The registration requirement applies regardless of the dollar value of the project.

Protecting Yourself When Hiring in Iowa

Verify the contractor's Division of Labor registration before hiring. Ask for the registration number and confirm it is active and not expired on LicensedCheck.com. Check that the contractor's primary activity matches the type of work you need done.

Request proof of general liability insurance and workers compensation coverage. Get a written contract with the scope of work, price, payment schedule, and the contractor's registration number.

Watch for these red flags: a contractor without a Division of Labor registration, an expired registration, anyone without proof of insurance, and contractors who demand full payment upfront. Verify registration first at LicensedCheck, then hire.
