Montana to Iowa: general contractor license reciprocity

Iowa gives no credit for a Montana general contractor license. You qualify from scratch.

Everyone registers the same way; an out-of-state contractor license transfers nothing

Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.

A commercial or general contractor licensed in another state gains nothing from that license in Iowa and loses nothing by not having one. DIAL does not evaluate out-of-state credentials for contractor registration, publishes no reciprocity or endorsement route, and has nothing to waive, because Iowa holds no contractor examination and sets no experience requirement. Iowa is not one of the state agencies that accept the NASCLA Accredited Examination for Commercial General Building Contractors, for the same reason. The one way an arriving contractor is treated differently is the bond: a business whose principal place of business is in another state must file a continuous $25,000 surety bond on DIAL's bond form, from a surety licensed in Iowa, or show that the Iowa Department of Transportation has prequalified it to bid on department projects. A branch office in Iowa does not change that, and every out-of-state subcontractor registers and bonds separately rather than working under the general contractor's registration. Otherwise the route is identical for everyone: get an Iowa unemployment insurance employer account number, file the workers' compensation certificate naming DIAL as certificate holder or a statement that coverage is not required, file the application with the ownership and business details, and pay $50 for a year or $150 for three. The number is issued within 30 days, and no work may start before it arrives.

Whether a business is out-of-state for bonding purposes turns on the seven factors in 481 IAC 465.2 - where the home office is shown on government filings, where payroll is prepared, where business is transacted, where the officers or owners live and work, where the bank accounts are, where fixed business property is, and where management decisions are made - rather than on where the company is incorporated. The $25,000 figure is a tax and unemployment-contribution guarantee running to the State of Iowa, not a measure of capacity or a performance bond, so a commercial contractor will still need separate bid, performance and payment bonds by contract or under the public works statutes. DIAL may require a larger bond after a hearing if the department of revenue or DIAL finds the state's tax exposure greater than the bond. Working or bidding without a registration draws a citation of up to $500 for a first violation and up to $5,000 for each later one, with 15 working days to contest before the employment appeal board.

What you must already have

  • Registration is required of every contractor doing business in Iowa that earns at least $2,000 a year from construction, including out-of-state businesses, joint ventures, construction management firms, design-builders and every subcontractor on the job.Iowa Code 91C.1(1)(a) and 91C.2; 481 IAC 465.1 and 465.3. The scope of 'construction' comes from 871 IAC 23.82(96), which covers building construction, land subdivision and development, heavy construction such as highways, power plants and pipelines, and special trade contracting, and which names general contractors, design-builders, engineer-constructors, joint-venture contractors, turnkey construction contractors and construction management firms.
  • No examination result, trade experience, education, apprenticeship, reference or financial statement is asked for at any point, so an out-of-state general contractor license, a NASCLA examination transcript and documented years in business are all equally irrelevant to the decision.The conditions of registration are exhaustively listed at Iowa Code 91C.2 and the application contents at 481 IAC 465.4; neither mentions qualifications, competency or another jurisdiction's license.
  • A contractor whose principal place of business is in another state must bond. Opening a branch office in Iowa does not make the business an in-state contractor if it is primarily based elsewhere, and the department applies a seven-factor test to decide.Iowa Code 91C.2(3) and 481 IAC 465.2 and 465.4(11). The alternative to the bond is a letter from the Iowa Department of Transportation confirming prequalification to bid on department projects under Iowa Code 314.1.

What you'll do to get licensed in Iowa

  1. 1Application fee. Pay the application fee ($50). Contractor registration fee: $50 per year, or $150 for a three-year registration, non-refundable. Registration renews annually, and a renewal form is sent by mail or email the month before expiry; renewing on time keeps the same registration number. A self-employed contractor who does not pay more than $2,000 a year to employ other people and does not work with or for other contractors in the same phase of construction is fee exempt and files a fee exemption form, which must be filed again at each renewal. Credit card and ACH payments are not accepted over the phone. A contractor registering through the Plumbing and Mechanical Systems Board's joint application pays a fee prorated to the length of that licensing period instead..
  2. 2Surety bond. Post a surety bond ($25,000). Out-of-state contractor bond: a $25,000 surety bond on DIAL's own bond form, from a surety company licensed to do business in Iowa, required of every contractor whose principal place of business is in another state, and of every out-of-state subcontractor in its own name. The bond is continuous until the surety cancels it on at least 30 days' written notice to both the contractor and DIAL, and guarantees payment of all taxes, unemployment compensation contributions, penalties, interest and related fees accruing to the State of Iowa from the work. Only the State of Iowa and its agencies may collect on it. DIAL may order the amount increased after a hearing where the state's tax exposure exceeds it. A contractor prequalified by the Iowa Department of Transportation to bid on its projects may file that letter instead. Release requires a written request from the surety and clearance from the department of revenue and the unemployment insurance services division..
  3. 3Insurance. Carry the required insurance. Workers' compensation: a certificate of insurance from the carrier showing the effective dates of coverage and naming the Department of Inspections, Appeals, and Licensing as certificate holder, filed every year. A self-insured employer files the commissioner of insurance's release under Iowa Code 87.11, and a contractor with no employees files a statement that it is not required to carry coverage. The insurer must notify DIAL of cancellation, the contractor must give DIAL ten days' notice before any change in coverage, and a lapse is grounds to revoke the registration after a fact-finding interview..
  4. 4Business license. Obtain a business license. An Iowa unemployment insurance employer account number from the unemployment insurance services division of Iowa Workforce Development, obtained before the registration application is filed. It is required of in-state and out-of-state contractors alike, even those with no employees. The application also needs a federal employer identification number for a business entity, or the owner's Social Security number for a natural person, and the business's NAICS code or a description of its principal products and services..
  5. 5Other. The registration application, filed through DIAL's online contractor registration portal or on the department's paper form, giving the business name, the mailing address of the principal place of business, the business telephone number, the entity type and the name, address, telephone number and position of each corporate officer or each owner. The registration number - the letter C followed by six digits - issues within 30 days of a complete application, is a public record, and must be obtained before any construction work is performed in Iowa..
  6. 6Other. Separate trade licensing where the work calls for it. Registration does not authorize plumbing, mechanical, HVAC, refrigeration, sheet metal or hydronic work, which needs a contractor license from the Iowa Plumbing and Mechanical Systems Board under chapter 105 - obtained on a joint application that issues the contractor registration number at the same time - or electrical work, which needs a license from the Iowa Electrical Examining Board under chapter 103. Asbestos, lead-based paint, elevator, boiler, alarm system and fire protection system work each carry their own DIAL credential. A general contractor usually meets these by subcontracting to, or employing, the appropriately licensed firm..
  7. 7Other. Registration before permits and before public contracts. A state or local official may not issue a building permit, certificate or authorization to a contractor who is required to hold a contractor registration number and has not obtained one, and a contractor who is not registered may not be awarded a contract to perform work for the state or a state agency. DIAL also directs contractors to contact the city or county government for each project to confirm local requirements, and the Iowa Department of Revenue publishes the sales and use tax rules that apply to construction contractors..

Issued by Iowa Department of Inspections, Appeals, and Licensing (DIAL), Contractor Registration

Iowa's commercial and general building tier is the same credential described at the residential level: a single construction contractor registration with the Department of Inspections, Appeals, and Licensing, with no classes, no letters, no monetary limits and no separation between house and commercial work. Iowa does not license general contractors at all. Chapter 91C of the Iowa Code and 481 Iowa Administrative Code chapter 465 set out the whole of what registration takes, and they contain no trade examination, no business-and-law examination, no experience requirement, no net worth or financial statement test, no continuing education and no qualifying party. The scope is set by the employment security definition of construction, which covers building construction, heavy construction such as highways, power plants and pipelines, and every special trade, and which names 'general contractors, design-builders, engineer-constructors, joint-venture contractors, and turnkey construction contractors' among the establishments it reaches. Registration is held by the business, and a joint venture registers as an independent entity in its own right. What the state verifies is compliance rather than competence: an Iowa unemployment insurance employer account number, workers' compensation coverage or a statement that it is not required, a $50 annual fee, and a $25,000 surety bond from any contractor whose principal place of business is outside Iowa. Registration matters commercially as well as legally - a building official may not issue a permit to an unregistered contractor, and an unregistered contractor may not be awarded a contract for work for the state or a state agency. Iowa's real competency licenses are in the trades: electricians under chapter 103 and plumbing, mechanical, HVAC, refrigeration, hydronic and sheet metal contractors under chapter 105.
