Iowa — How to Check a Contractor's License

Iowa requires contractors to hold a state license for projects exceeding $2,000+ annual construction work triggers registration in labor and materials. The Department of Inspections, Appeals and Licensing (DIAL) oversees licensing, complaints, and disciplinary actions.

Step 1: Get the Contractor's License Number

Any legitimate contractor in Iowa should readily provide their license number. It should appear on their business card, vehicle, website, and advertising. If a contractor refuses to share their license number, don't hire them.

Step 2: Verify the License

Visit the Department of Inspections, Appeals and Licensing (DIAL) website to look up the contractor's license. We're working on adding Iowa license data to our search tool — check our Iowa page for updates.

When checking the license, verify:

• Status is "Active" — not expired, suspended, or revoked
• Name matches — the business name on the license should match who you're hiring
• Classifications cover your project — a plumbing license doesn't cover electrical work
• License won't expire during your project

Step 3: Check Bond and Insurance

Iowa requires licensed contractors to carry a surety bond ($5,000 (in-state); $25,000 (out-of-state contractors)). The bond protects consumers if the contractor violates state regulations or abandons a project. Ask the contractor for proof of their bond, and verify it through the Department of Inspections, Appeals and Licensing (DIAL).

Step 4: Check Complaint History

The Department of Inspections, Appeals and Licensing (DIAL) tracks complaints filed against licensed contractors. Before hiring, check if the contractor has any past disciplinary actions, complaints, or violations. Visit the Department of Inspections, Appeals and Licensing (DIAL) website to check complaint history.
