Iowa's credential is a contractor registration. Under chapter 91C of the Iowa Code, a contractor doing business in the state is required to register with the director and to meet the conditions the chapter attaches to registration [1]. The work is defined by cross-reference: a contractor is a person engaged in the business of construction, with "construction" taking the meaning the Iowa administrative code gives it for chapter 96, the employment security law [1].
The registration is run by the Contractor Registration program of the Iowa Department of Inspections, Appeals, and Licensing (DIAL). The department traces the program to 1988 and describes its aim as employer compliance with workers' compensation and unemployment insurance tax laws [2].
The chapter draws its line by income and by whose property is involved. A person earning less than two thousand dollars annually [1] falls outside the chapter's definition of a contractor, as does a person who performs work, or has work performed, on the person's own property [1]. DIAL's page states its line as construction earnings of at least $2,000 [2] a year.
Conditions of registration
The conditions of the contractor registration sit in section 91C.2 [1].
Workers' compensation comes first. A registrant complies with Iowa's workers' compensation insurance law and each year supplies one of the following: evidence of coverage, evidence of relief from the requirement under section 87.11, or a statement that coverage is not required [1].
Another condition ties back to the employment security law. The contractor holds either an employer account number or a special contractor number issued by the department of workforce development under chapter 96 [1].
A further condition applies to contractors from out of state. Such a contractor either files a surety bond of twenty-five thousand dollars with the department, as section 91C.7 provides, or gives the department a statement that it is prequalified to bid on department of transportation projects under section 314.1 [1].
What registration costs
The rule in 481 IAC chapter 465 sets the standard fee: as of February 26, 2025, the standard registration fee is $50 per year [3], and a three-year registration is also offered. DIAL describes the annual fee as non-refundable [4].
The chapter also carves out a fee exemption. A contractor whose application shows self-employment, no more than two thousand dollars a year [1] paid to employ others in the business, and no work with or for other contractors in the same phases of construction is exempt from the chapter's fee requirements.
Penalties for failing to register
When the director, or the director's authorized representative, believes after investigation that a contractor has violated the registration requirement, the director issues a citation to the contractor [1].
The chapter then sets ceilings on the administrative penalties that may be imposed. For a first violation the cap is five hundred dollars, and for each second or subsequent violation it is five thousand dollars [1]. These are maximums, not fixed amounts.
