Colorado to Idaho: residential contractor license reciprocity
Colorado does not issue a statewide residential contractor license, so there is nothing to transfer. Here is Idaho's standard path for out-of-state applicants.
Your origin state does not issue a statewide license at this level, so there is no license to transfer. The destination's standard out-of-state path is shown; expect to meet it in full.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Registration for every applicant, wherever they come from (all states)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
An out-of-state contractor license is worth nothing in Idaho, and it is not needed, because Idaho asks nothing of a residential builder that another state's license could stand in for. The registration application requires the form, the owners' names, proof of general liability and workers' compensation insurance, disclosure of any felony conviction and of any contractor license or registration denied, surrendered, suspended or revoked anywhere, and the fee. There is no trade examination, no law examination, no experience requirement, no bond and no financial statement, so there is nothing an incoming builder can have waived and nothing that documented out-of-state years can shorten. A builder arriving from any state registers on exactly the same terms as an Idaho resident, and a contractor based outside Idaho may register without moving here. DOPL publishes no reciprocity agreement and no endorsement route for contractor registration, and the application forms offer no box for one.
Three things are worth knowing about routes that look like they might exist here. First, the universal licensure statute, Idaho Code 67-9409, does reach registrations as well as licenses, and the Contractors Board's rule chapter names it as authority, but the statute only requires an agency to license an out-of-state holder who demonstrates competency by that agency's own methods, and it forbids the agency from asking more of a universal-licensure applicant than of a standard one. Because the Board sets no competency requirement for anybody, universal licensure changes nothing for contractors and there is no separate universal-licensure application, box or fee. Second, the Act contains a section headed reciprocal registration, Idaho Code 54-5213, and the fee rule sets a reciprocal fee, but that section applies only to a contractor holding a city or county license issued inside Idaho under an ordinance adopted before 1 January 2007; it does not reach a credential from another state, and the same section is what stopped Idaho cities from licensing contractors at all. Third, DOPL does not take the NASCLA Accredited Examination for contractor registration, Idaho is not among the state agencies listed as accepting it, and there is no Idaho trade examination for it to replace; NASCLA's electrical list does name the Idaho Electrical Board, but that is a different credential for a different trade. Registration is also not a competency credential in the other direction: it does not qualify anyone to do plumbing, electrical or HVAC work, and it does not let anyone bid public works.

What you must already have
- No examination, experience, apprenticeship, education or qualifying party is required of anyone. An applicant with thirty years and a general contractor license in another state and an applicant with no credential at all face the same requirements.Idaho Code 54-5210 lists what the application must contain and none of it is a competency test; IDAPA 24.21.01 adds only the felony qualification and the fee schedule, and its examination, experience and continuing education sections are reserved and empty.
- You must have no disciplinary action or unresolved complaints on your record.This is the one place where an out-of-state record matters, and it can only count against the applicant. Idaho Code 54-5210(1)(g) requires the statement; both registration forms ask the question and the Disclosure Statement on the last page collects the detail.
- No felony conviction in any state or federal court. An applicant who has one may ask the Board in writing for an exemption review, in which the Board reads the court records and anything the applicant submits about suitability, may grant an interview, and decides; the applicant carries the burden of establishing suitability.IDAPA 24.21.01.100.01. Idaho Code 67-9411 requires the Board to weigh the seriousness of the crime, its relationship to contracting, the time since it was committed and evidence of rehabilitation rather than treating a conviction as an automatic bar, and allows a one-year conditional registration instead of a denial.
What you'll do to get licensed in Idaho
- 1Application fee. Pay the application fee ($120). Application fee, which includes the original registration. DOPL's published schedule, effective 1 July 2026, is $120 for an individual and $120 for a business, then $60 to renew for one year or $120 to renew for two, with a $40 reinstatement fee on top of the renewal fee after a lapse. The Board's rule caps the fee at $60 a year and allows annual fees to be aggregated for a two-year registration, and Idaho Code 54-5210(2) caps it at $150 a year. The mailed paper application forms, last updated in February 2024, still print a $50 processing fee, so confirm the current amount with the Board on (208) 334-3233 or [email protected] before sending a check. A contractor who already holds an Idaho public works contractor or construction manager license registers without paying the fee..
- 2Insurance. Carry the required insurance. Certificate of general liability insurance, including products and completed operations coverage for the applicant's construction operations, of not less than $300,000 single limit, issued by an insurance company authorized to do business in Idaho. DOPL asks that the insured, not DOPL, be named as the certificate holder. The coverage has to stay in force for as long as the registration is active, and letting it lapse is a ground for discipline or revocation..
- 3Insurance. Carry the required insurance. Workers' compensation insurance certificate from a carrier authorized to do business in Idaho, or a written statement explaining why the coverage is not required of the applicant under Idaho Code 72-101 through 72-230, for example because the registrant has no employees. A registrant who takes on employees later has to put the coverage in place..
- 4Background check. Complete a background check. The application is submitted under oath and asks whether the applicant has ever received a conviction, finding of guilt, withheld judgment or suspended sentence for a felony in any state, and whether the applicant or anyone with an ownership interest has ever had a contractor license or registration denied, surrendered, suspended, revoked or otherwise disciplined anywhere. A yes to either question means filing DOPL's disclosure form with the court records or the other state's board order. The Board evaluates a conviction for current relevance to fitness under Idaho Code 67-9411 and may run an exemption review. DOPL is separately authorized by Idaho Code 67-9411A to require fingerprints and an Idaho State Police and FBI records check of license applicants, but the Contractors Board's rule and its registration forms ask only for the sworn disclosure..
- 5Other. Social security number for an individual applicant or an employer tax identification number for a business; the business name and address of record, which becomes a public record; a mailing address, business phone and email; the first and last name of every principal, member, partner, shareholder or other owner, which for a business applicant must be people rather than another entity; one construction type code; and a statement of the type of construction to be undertaken. The application stays open for one year from the date it is filed, after which unfinished applications are terminated and a new application is needed..
- 6Other. Within 60 days of registering, the registration number must be displayed at the place of business and at every jobsite and printed on all advertising, contracts, building permits, letterheads, purchase orders and subcontracts. A building official will ask for the number before issuing a permit, and a registrant is also responsible for obtaining satisfactory proof that every other contractor engaged on the job is registered..
- 7Surety bond. Post a surety bond (if applicable). Idaho requires no surety bond for contractor registration. A homeowner may require one at their own expense up to the value of the project, and before signing a residential contract over $2,000 a general contractor must give the homeowner a written disclosure that says so, along with disclosures about lien waivers, proof of liability and workers' compensation insurance, and extended title insurance..
Published fees on this path total $120, excluding exam-vendor fees, bonds, and insurance.

How Idaho licenses residential contractors
Idaho residential contractor · “Contractor Registration (construction type 002, General Residential Builder)”
Statewide license
Issued by Idaho Contractors Board (Division of Occupational and Professional Licenses)
Idaho does not license residential building contractors; it registers them. Under the Idaho Contractor Registration Act, anyone who takes on a construction job worth more than $2,000 in labor and materials must be registered with the Idaho Contractors Board, which the Division of Occupational and Professional Licenses (DOPL) administers, and that registration is the only statewide credential a homebuilder or remodeler needs. Registration carries no trade examination, no business and law examination, no experience or apprenticeship requirement, no bond, no net worth test and no qualifying party: an individual registers in their own name, and a partnership, LLC or corporation registers as a business and lists the people who own it, with nobody having to demonstrate competence on the company's behalf. What the applicant must produce is insurance, an ownership list and an honest history: a general liability certificate of at least $300,000 single limit, workers' compensation coverage or a written statement of why it is not required, and sworn answers about any felony conviction and about any contractor license or registration denied, surrendered, suspended or revoked in any state. Applicants pick a single construction type code, such as 002 General Residential Builder or 003 General Remodel Builder, but DOPL says plainly that the code chosen does not limit the work performed. Registration does not authorize plumbing, electrical or HVAC work, which are separately licensed trades whose licensees are exempt from registering, and Idaho Code 54-5213 bars cities and counties from running their own contractor registration or licensing programs, so there is nothing local to add on top.
Why Colorado has nothing to transfer
Colorado residential contractor · “Residential / Home Builder contractor license (Class C in most jurisdictions)”
Licensed by cities and counties
Colorado issues no statewide residential or home builder contractor license. DORA's consumer page says plainly that general contractors are not licensed at the state level and tells consumers to check with their city, and the Pikes Peak Regional Building Department's exam notice states that "Colorado does NOT have a state license for the building or mechanical trades." Homebuilding is licensed instead by each city, county or regional building department, most of which use a Class C tier for one- and two-family dwellings; Denver calls it Residential Contractor Class C, Colorado Springs calls it Building Contractor C (Home Builder), Fort Collins splits it into Classes D1 and D2, and Aurora calls it Residential Building Contractor. The license is normally issued to the contracting business and is qualified by a named individual who holds the supervisor certificate, so an arriving builder usually applies for the personal certificate first and the company license second. Almost every licensing jurisdiction accepts the same underlying credential - the ICC National Standard Residential Building Contractor (C) examination - which makes the exam, rather than an out-of-state license, the thing that actually travels. A license must be obtained in each jurisdiction where the builder will pull permits, and a few places, such as unincorporated Douglas County, require only registration and no exam at all.
How local licensing works in Colorado
How local licensing works. There is no state contractor board, so each city, county or regional building department writes its own contractor ordinance under its building code. Class letters mean different things in different places, and holding a license in one Colorado jurisdiction does not let you pull permits in the next one. Most jurisdictions build the residential tier around the ICC National Standard Residential Building Contractor (C) examination, which is open book, multiple choice and delivered by Pearson VUE; the same exam appears under different ICC exam IDs (W13, F13, G13) because each jurisdiction adopts a different edition of the building code and requires a current one. Passing an ICC exam is not itself a license - it is a credential you then present to each building department, which also verifies your experience.
Denver. Licensing is two steps. The individual first earns a Residential Contractor Class C supervisor certificate, which covers erecting, adding to, altering or repairing one- and two-family dwellings, U occupancy buildings and attached single-unit dwellings (IRC townhouses). It requires two years of field work as a journeyman carpenter or construction foreman with foundation, framing and roofing experience, documented with notarized letters, plus ICC exam #F13 National Standard Residential Building Contractor C. The certificate costs $60 and renews every three years. The business then applies for the Residential Contractor Class C license, $250 for three years. Denver states that it "does not accept or reciprocate contractor licenses and/or certificates from other counties or states."
Colorado Springs, El Paso County and nearby towns (Pikes Peak Regional Building Department). PPRBD licenses for unincorporated El Paso County, Colorado Springs, Fountain, Manitou Springs, Green Mountain Falls, Monument, Palmer Lake, Calhan and Woodland Park. Building Contractor C (Home Builder) covers one- and two-family dwellings up to three stories plus accessory structures, and R-2 buildings of up to eight units and two stories; the license fee is $150 with a $50 non-refundable application fee. Building Contractor E covers residential accessory structures and interior nonstructural remodeling, $75. Applicants file three reference forms documenting experience, a liability insurance certificate naming PPRBD, a workers' compensation certificate or rejection of coverage, a Colorado certificate of good standing and a name-based judicial record check; the Licensing Committee and Board of Review act on each file. PPRBD accepts ICC National Standardized or ICC Colorado Standard exams passed on or after January 1, 2016 and states that "no out-of-state exams will be accepted."
Aurora. Residential Building Contractor "Requires ICC Residential Building Contractor 'C' Certification"; the supervisor license fee is $131 and the license fee is $235, and registration plus three job references are also required. Remodeling contractors register with three years of documented experience instead of taking an exam.
Fort Collins. The residential-only classes are D1 (single-family attached and detached, no more than two dwelling units, townhouses), D2 (detached garages and Group U Division 1 occupancies up to 1,000 sq ft), E(R) nonstructural residential alterations and MM. All of them require ICC exam G13, plus three project verifications, each with the permit and the final inspection or certificate of occupancy, signed by someone unconnected to the applicant's company. General liability of $1,000,000 per person and $2,000,000 per accident and aggregate is required. A new license with supervisor certificate is $300 for two years, including a $75 non-refundable application fee.
Boulder. Class C covers construction, alteration, wrecking or repair of any detached one- and two-family dwelling or townhome and requires the ICC C Contractors certificate. Boulder states that it "does not accept reciprocal licenses from other jurisdictions," and its license covers work inside city limits only. Fee amounts are published in Boulder's contractor license application and schedule of fees.
Jefferson County. For unincorporated Jefferson County, a Class C license (labeled 2018 G13) covers one- and two-family dwellings and accessory buildings. The county accepts "proof that you have passed an appropriate ICC exam within the last 3 years or ... a copy of a valid license issued from an ICC participating jurisdiction." The fee is $50 and the license renews annually.
Arapahoe County. Building Contractor Class C (residential) costs $180 and requires an ICC Class "C" certification or an equivalent certification from a recognized state or national certification entity. General liability of $1,000,000 per occurrence and $2,000,000 aggregate must name the county.
Lakewood. Contractors register with Public Works; class A-3 Residential covers new construction and remodeling. The registration page does not impose an exam on general contractors but asks A-1 and A-2 applicants to attach any ICC certifications held. The fee is $150 for the first probationary year and $400 for each subsequent three-year renewal.
Douglas County. Unincorporated Douglas County requires registration rather than a license and states that it "has no testing requirements." Registrants file the application, workers' compensation proof or an exemption statement and business liability insurance naming the Building Division; registration fees are currently waived and applications are processed in about two business days.
Out-of-state holders. No Colorado jurisdiction reviewed grants a residential contractor license on the strength of another state's license. Denver and Boulder say so expressly, and PPRBD will not accept out-of-state exam results. The practical route is to pass the ICC National Standard Residential Building Contractor (C) exam on a code edition the jurisdiction currently accepts, gather documented project experience and references, and then apply separately in each city or county where you intend to build. Jefferson County is the clearest exception: it will take a current license from another ICC participating jurisdiction in place of the exam. Confirm the class, exam code year and fee with the building department before applying, because these change independently in every jurisdiction.
