All “construction” contractors doing business in
Iowa and making more than $2,000.00 per year
must be registered with the Iowa Division of Labor.
“Construction” is defined very broadly to include
companies or individuals who perform electrical,
plumbing, roofing, house painting, installation of
landscaping, windows, cable, elevators and many
other activities.
Plumbing, HVAC/R, Hydronics, and Mechanical Professionals
If you require a license with the Plumbers & Mechanicals Systems Board (PMSB), do not complete this form. Instead please
visit or call 866-280-1521 to complete registration and licensing together.
Fee Exemption
Self-employed contractors who meet the specific criteria may send a completed signed and notarized Fee Exemption
form instead of payment. To qualify for registering without payment, a self-employed contractor must not work with or for
other contractors in the same phases of construction and must not pay more than $2,000.00 per year to employ others.

Out-of-State Contractors
Out-of-state contractors must file a $25,000.00 surety bond at the time of registration. The bond must meet three criteria in
order to be valid: 1) the bond must be executed by a surety company licensed to do business in Iowa, 2) the bond must be
issued on the Out-of-State Bond form provided at with the bonding company's seal and two original
signatures, and 3) the bonding company must attach their Power of Attorney (POA) to the form. Once we have accepted a
valid bond, we consider it continuous until we receive a bond cancellation from the bonding company. If an out-of-state
contractor is pre-qualified to bid on projects for the Iowa Department of Transportation (DOT), they may submit their DOT-
issued pre-qualification letter in lieu of a bond.
Unemployment Insurance Number
You must obtain an unemployment insurance number before applying for contractor registration even if you have no
employees. To obtain a UI# visit or contact customer service at 888-848-7442 or
Workers’ Compensation
A contractor with one or more employees must submit proof of workers’ compensation insurance. In most cases employers
must submit a certificate of insurance showing an effective date and listing the Division of Labor as a certificate holder. A
self-insured contractor shall submit a Certificate of Relief from the Iowa Insurance Division.
