Colorado to Arizona: residential contractor license reciprocity

No credit· Start overVerified September 17, 2026· 13 sources

Colorado does not issue a statewide residential contractor license, so there is nothing to transfer. Here is Arizona'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.

Out-of-state waiver of the trade examination and experience (every origin state)

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

Arizona has no reciprocity agreement with any state, so every inbound applicant follows the same route and no origin state is treated better than another. The Registrar's own words are: "Arizona does not have direct reciprocity with any state; however, the Registrar does offer out of state applicants the opportunity to request a waiver of the required trade exam and experience, if the qualifying party has held a comparable license in another state within the past 5 years of the application date and the license was obtained by a trade examination." You request that waiver on Form RC-L-200G, Out-of-State Waiver Request Form: you fill in your side, send it to the agency that issued your license so it can verify your license history, exams and years of experience and stamp it with a state seal, and then enclose the returned form with your Arizona license application in place of a trade exam result. The waiver is discretionary and is not pre-approved, so it is reviewed only once your complete application is in; if it is refused you sit the Arizona B General Residential Contractor trade exam through PSI. The Arizona Statutes and Rules Exam is never waived on this route, because it cannot be waived for anyone who has not been the qualifying party on an Arizona contractor's license within the past five years. Everything else on the checklist still applies: four years of trade experience, a license bond, the Residential Recovery Fund assessment, background checks for every person named on the application, entity registration and the fees.

The rule behind the waiver is A.A.C. R4-9-106(E)(1): the Registrar "may waive the trade examination requirement if records reflect that the qualifying party is currently or has previously been a qualifying party for a licensee in the other state in the same classification, or in a comparable classification, within the preceding five years." Because it is written as "may waive", it is a case-by-case decision rather than an entitlement, and comparability of your out-of-state classification to the Arizona B classification is the Registrar's call. Form RC-L-200G also cites A.R.S. 32-1122(A)(4), A.R.S. 32-1122(E)(1) and A.R.S. 32-4302 and says that a qualifying applicant may see "the waiver of the examination requirements, experience requirements, or both." A.R.S. 32-4302 is Arizona's universal licensing recognition statute: it requires a Title 32 license to be issued to a person who establishes residence in Arizona and who has held a good-standing license in another state at the same practice level for at least a year, obtained by examination where the other state required one, with no discipline or pending investigation; subsection (C) preserves the state-laws exam, so the Arizona Statutes and Rules Exam still applies. The Registrar's Service Members and Veterans page publishes the no-examination version of that statute for the spouse of an active-duty member accompanying the member to an Arizona duty station, and waives the initial application fee for that spouse and for a veteran discharged within the past two years applying as a sole proprietor for the first time. Separately, A.A.C. R4-9-106(F) lets the Registrar waive the experience requirement in whole or in part on the strength of an appropriate trade examination passed within the past two years or a valid, nationally recognized certification. The Registrar publishes no processing time for application review or approval; ask at [email protected], 602-542-1525 or 877-692-9762.

What you must already have

  • You are currently, or have been within the preceding five years, the qualifying party for a licensed contractor in another state in the same classification or in a classification the Registrar finds comparable to the Arizona B General Residential Contractor classification.A.A.C. R4-9-106(E)(1)(b). The Registrar's applying page states the same test as having "held a comparable license in another state within the past 5 years of the application date". Comparability is decided by the Registrar; there is no published list of equivalent out-of-state classifications and no pre-approval, so the decision is made when the completed application is reviewed. The verification is done by the issuing agency on Form RC-L-200G, which asks it for your current license status, the date you were first named on the license, the number of years of experience it can verify, the exams you took and the name and date of the passing exam, under the agency's state seal.
  • Your Colorado license must have been obtained by examination, not by reciprocity or grandfathering.
  • You must have passed a licensing exam in Colorado that the destination considers comparable.The Registrar's applying page says applicants "for the KB-1 Dual Building Contractor and KB-2 Dual Residential and Small Commercial license classifications may take the National Association of State Licensing Agency Commercial General Building Exam in lieu of the AZ ROC trade exam", and its licensing-fees page extends the same option to the B-1 and B-2 commercial classifications. Read the scope carefully if you only want to build houses: no AZ ROC page extends NASCLA acceptance to the standalone B General Residential Contractor classification, so NASCLA reaches residential work only through the KB-1 or KB-2 dual license, which costs more and carries a combined residential and commercial bond. The NASCLA exam is an exam credential rather than a license or an agreement between states: anyone may sit it in any participating jurisdiction, and it waives no other Arizona requirement, including the Arizona Statutes and Rules Exam.
  • Four years of practical or management trade experience in residential construction, at least two of them within the last ten years. Accredited college, university or manufacturer training may substitute for up to two of the four years. Experience earned in other states counts.A.R.S. 32-1122(E)(1) and the Registrar's License Classification Requirements, which set four years for the B, B-3, KB-1 and KB-2 classifications and state that the years "must be hands-on and/or managerial experience". A.A.C. R4-9-119 requires the Registrar to accept military service or training, diplomas or transcripts from accredited training programs, and completion certificates from an apprenticeship approved by the US Department of Labor or a state apprenticeship agency, and to accept experience regardless of whether you were licensed or working for a licensed entity at the time. The Registrar may also reduce the four-year requirement where custom and usage in the craft shows it to be excessive, and under A.A.C. R4-9-106(F) may waive experience in whole or in part on the strength of a trade exam passed within the past two years or a valid nationally recognized certification. Form RC-L-200G can waive the experience requirement as well as the exam when the out-of-state agency verifies your years.
  • You must have no disciplinary action or unresolved complaints on your record.A.R.S. 32-1122(C) and (D). The Registrar may find the circumstances behind a denial, refusal or revocation excusable if your actions did not result in an unremedied hardship, danger or loss to the public. Prior-license, felony and unlicensed-activity disclosure forms go in with the application where they apply.

What you'll do to get licensed in Arizona

  1. 1Law / code exam. Pass a law, rules, or code exam. Arizona Statutes and Rules Training Course and Exam (SRE), a computer-based open-book course and exam offered only online through Gmetrix. It covers the building, safety, health and lien laws of the state, the administrative principles of the contracting business and the Registrar's rules, and a grade of at least 70 percent is required. It cannot be waived unless the qualifying party has been the qualifying party on an Arizona contractor's license within the past five years, so an out-of-state applicant always takes it..
  2. 2Exam fee. Pay the exam fee ($61). Examination fee for the online Arizona Statutes and Rules Training Course and Exam, paid directly to Gmetrix..
  3. 3Trade exam. Pass the destination's trade exam (if applicable). B General Residential Contractor trade exam, taken online or at a testing center through PSI Services, with a passing grade of at least 70 percent and taken not more than two years before you apply. It is required only if the Registrar does not grant your out-of-state waiver. The Registrar has combined the B, B-3 and CR-61 exams into a single exam, so one sitting covers whichever of those classifications you apply for. After a failure you wait 30 days to retake, 30 days after a second failure and 90 days after any further failure..
  4. 4Exam fee. Pay the exam fee ($66) (if applicable). Examination fee for a trade-specific exam, taken either online or at a testing center, paid directly to PSI. Payable only if you sit the Arizona trade exam rather than obtaining a waiver..
  5. 5Application fee. Pay the application fee ($180). Application fee for a General Residential classification (B, B-3, B-4, B-5, B-6, B-10). A General Dual classification such as KB-1 or KB-2 has a $200 application fee instead. The Registrar waives the initial application fee for a first-time sole proprietor applicant who is the spouse of an active-duty service member, or a veteran discharged not more than two years before the application date..
  6. 6License fee. Pay the license or certificate fee ($320). License fee for a General Residential classification, making $870 in total with the application fee and the Residential Recovery Fund assessment. A General Dual license (KA, KB-1, KB-2) costs $480 in license fee and $1,050 in total. Renewal is $320 plus a $270 recovery fund assessment, or $590 in total; a General Dual license renews at $480 plus $270, or $750..
  7. 7Other. Residential Recovery Fund assessment. Every applicant for a residential or dual classification pays it, even if a license fee waiver is approved. The alternative to the assessment is posting a surety or cash bond of $200,000 to the license. ($370).
  8. 8Surety bond. Post a surety bond ($9,000). Contractor's license bond on the Registrar's bond form, sized by classification and by the gross volume of work you expect to do in Arizona. For the residential general classes (B, B-3, B-4, B-4R, B-5, B-5R, B-6, B-10) it is $9,000 for contemplated gross volume under $750,000 and $15,000 at $750,000 or more. A dual license such as KB-1 or KB-2 combines the residential and commercial amounts and the penal sum must be split on the bond between the residential and commercial figures. A surety bond, cash, or a certificate of deposit from a bank operating in Arizona is accepted. The effective date cannot be in the future and must be within six months of submission, the attorney-in-fact's signature must be notarized, the bond company's seal must be attached, and corrections must come from the bond company as a rider rather than by hand..
  9. 9Insurance. Carry the required insurance. Attestation that you have complied with the statutes and rules governing workers' compensation insurance. If the business is required to carry workers' compensation under Arizona law, the attestation must give the policy number or be accompanied by proof of self-insurance..
  10. 10Background check. Complete a background check. A background check for every person named on the license application, obtained through the Registrar's background check vendor. A completed check expires 90 days from its completion date. Anyone who has had an international address must submit an international and domestic check and list every foreign and domestic address where they have lived..
  11. 11Business license. Obtain a business license. Entity registration. A limited liability company or corporation must be registered with the Arizona Corporation Commission and in good standing with it before the license application is submitted, and must stay in good standing to renew. A partnership registers with the Arizona Secretary of State. A sole proprietorship needs no entity filing. You may only contract and advertise under the entity name the Registrar has licensed, so any trade name you want to use must be entered on the application as a DBA; filing the trade name with the Secretary of State is recommended but not required..
  12. 12Other. A legible copy of a government-issued photo identification, such as a valid driver's license or passport, for every individual named in the Persons section of the license application. Applications are filed through the ROC Online Customer Portal, or mailed to Registrar of Contractors, P.O. Box 6748, Phoenix, AZ 85005-6748, or delivered to 1700 W. Washington Street, Suite 105, Phoenix, AZ 85007-2812..

Published fees on this path total $561, excluding exam-vendor fees, bonds, and insurance.

How Arizona licenses residential contractors

Arizona residential contractor · “B General Residential Contractor (KB-1 or KB-2 dual licenses also carry the B scope)”

Statewide license

Verified September 17, 2026· 4 sources

Issued by Arizona Registrar of Contractors (AZ ROC)

Arizona licenses residential contractors statewide through the Registrar of Contractors (AZ ROC), and there is no city or county residential builder license layered on top of it. The homes-only credential is the B General Residential Contractor classification, which allows the licensee to construct and repair all or any part of a residential structure or appurtenance; electrical, plumbing, air conditioning, boiler, swimming pool, spa and water well work must be subcontracted to an appropriately licensed contractor. B-3 General Remodeling and Repair Contractor is the narrower version for remodeling and repairing an existing residential structure. The Registrar uses classification prefixes to separate markets: plain B codes are residential general building, B-1 and B-2 are commercial general building, C- and R- are commercial and residential specialty trades, CR- is specialty dual, and K codes are general dual. A contractor who wants both residential and commercial building work takes a dual classification instead of two licenses: KB-1 Dual Building Contractor covers the B-1 and B scopes together, and KB-2 Dual Residential and Small Commercial covers the B-2 and B scopes together. The license is held by a business, not by a person: it may be issued to a sole proprietorship, partnership, limited liability company or corporation, and the Registrar states that "the license belongs to the business and not to the qualifying party." The reader of this page is the qualifying party, the regularly employed person who supplies the experience and passes the exams on the business's behalf, and who must hold four years of practical or management trade experience in this type of construction.

Why Colorado has nothing to transfer

Colorado residential contractor · “Residential / Home Builder contractor license (Class C in most jurisdictions)”

Licensed by cities and counties

Verified September 17, 2026· 18 sources

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.
