Colorado to Delaware: residential contractor license reciprocity

No credit· Start overVerified September 17, 2026· 18 sources

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

Everyone files the same registrations; a residential contractor license from another state transfers nothing

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

A residential builder or remodeler licensed in another state gains nothing from that license in Delaware, and a contractor who has never held one is no worse off. Delaware publishes no reciprocity, no endorsement and no credit for out-of-state experience, because it holds no examination and sets no competency standard for residential contractors that could be waived or matched. Delaware is also not one of the state agencies that accept the NASCLA Accredited Examination for Commercial General Building Contractors. The steps are the same for everyone: form or foreign-qualify the business, apply to the Division of Revenue for the contractor business license and pay $75, register with the Department of Labor's Office of Contractor Registration before any work begins, and carry Delaware workers' compensation insurance. A business that does not regularly maintain a place of business in Delaware is a nonresident contractor and must post a tax bond of six percent of any contract of $20,000 or more, or of the aggregate of two or more contracts reaching $20,000 in a calendar year, before construction starts; it must also name a Delaware custodian of records and agent for service of process on the Labor registration. If the work is in unincorporated New Castle County, add that county's building contractor license, which for a new home builder means Class A or above with a $150,000 surety bond and an approved warranty company.

Home improvement work is regulated by contract rather than by license. The Department of Justice's Home Improvement Services Regulation, effective November 1, 2023 under the Consumer Fraud Act, requires a written contract containing all material terms, an approximate completion date unless the contract clearly says none will be given, all final terms filled in before signing, express warranties written into the contract with any disclaimer made clearly and initialed, disclosure of cost-plus pricing with a good faith estimate, and the contractor's full contact details, and it forbids practices such as calling a binding contract an estimate or claiming the customer was specially selected for a discount. The contractor must give the homeowner the Attorney General's two-page rights summary before the contract is signed. Complaints go to the Consumer Mediation Unit on (302) 577-8600 or (800) 220-5424, and a contractor who does not take part in good faith in the dispute resolution process can have its certificate of registration denied, suspended or revoked. Delaware does not publish a processing time for either the business license or the contractor registration; the Division of Revenue Business Tax Department is (302) 577-8780 and the Office of Contractor Registration is [email protected].

What you must already have

  • Nothing about the applicant's trade history is examined. Neither the Division of Revenue nor the Department of Labor asks for an examination result, apprenticeship or work experience, education, references or a financial statement, so an out-of-state residential contractor license, a NASCLA examination transcript and twenty years of homebuilding all count for the same amount in Delaware, which is nothing.Confirmed against 30 Del. C. ch. 25 and 19 Del. C. ch. 36 read in full, the Division of Revenue's contractor guidance, the One Stop registration checklist and the Division of Professional Regulation's complete list of 37 boards, none of which covers contractors or home builders.
  • A business whose place of business is outside Delaware is a nonresident contractor. It must name a Delaware custodian of records and an agent for service of process on the Labor registration, and it must post the six percent tax bond before construction begins.30 Del. C. §2501(3), (6) and (7) turn on whether the entity 'regularly maintains a place of business in this State'; a site trailer used for one contract or related set of contracts does not create one, whatever its duration. Where a contractor entity is a partnership or joint venture, it is a resident if at least one constituent entity keeps a Delaware place of business. 19 Del. C. §3605(b)(3) requires the custodian and agent details.
  • The Labor registration application asks whether the business, or anyone holding a financial interest in it, has held an interest in an entity cited for a labor law violation, has been convicted of home improvement fraud or new home construction fraud under Delaware law, or has been found to have engaged in an unlawful trade practice. Labor law violations and fraud in the last two years must be listed with dates and outcomes.19 Del. C. §3605(b)(4), citing 11 Del. C. §916 (home improvement fraud), 11 Del. C. §917 (new home construction fraud) and 6 Del. C. §2513. A knowing violation of the Contractor Registration Act carries a civil penalty of $5,000 to $85,000 per violation, and the Department can ask the Court of Chancery to enjoin an unregistered contractor's work.

What you'll do to get licensed in Delaware

  1. 1Business license. Obtain a business license ($75). Delaware contractor business license from the Division of Revenue, required of any person or entity engaging in business in the State as a contractor, resident or nonresident, general contractor or subcontractor. The fee is $75 and the license runs to January 1, renewable annually by December 31; most licenses are pro-ratable in the first year. Apply through Delaware One Stop or a Combined Registration Application. For a competitively bid contract over $50,000 the license application must be initiated before the bid is submitted, or for a subcontractor before the general contractor bids. The Division will not issue the license until the nonresident bond obligation is satisfied, a certificate of notice from the Delaware Department of Labor is filed, and a certificate of workers' compensation insurance or qualified self-insurer status is filed..
  2. 2Business license. Obtain a business license ($200). Contractor Registration Certificate from the Department of Labor's Office of Contractor Registration, required before performing construction services or maintenance in Delaware. The one-year fee is $200 for private construction, $300 for public construction and $500 for both; after two consecutive years of registration a contractor with no labor law violations who renews on time may take a two-year certificate for $300 (private) or $500 (public). The application asks for tax identification numbers, NAICS codes, entity details, contacts for everyone with a financial interest, the Delaware business license number, proof of Delaware workers' compensation coverage, the unemployment insurance SUI number, an OSHA-compliant safety plan, and the labor law and fraud disclosures. Renewal is only possible within the 90 days before expiry; an expired certificate means applying again from scratch. The certificate is not transferable..
  3. 3Surety bond. Post a surety bond (if applicable). Non-Resident Contractor Bond, required of a contractor that does not regularly maintain a place of business in Delaware. The amount is six percent of the contract or subcontract price on any contract of $20,000 or more, six percent of estimated cost and profit under a cost-plus contract of that size, or six percent of the aggregate where two or more contracts in one calendar year reach $20,000. It is filed with the Division of Revenue on the Division's own form before construction begins, and a bank letter of credit or a cash bond may be accepted instead. The Secretary of Finance may waive it in whole or in part where no bond is needed to protect state tax revenue, and issues a certificate of compliance for a project on request. This is a tax security for Delaware taxes, license fees, unemployment contributions and withholding, not a performance or consumer protection bond. Bonding questions: (302) 577-8167..
  4. 4Insurance. Carry the required insurance. Delaware workers' compensation insurance, evidenced by a certificate of insurance filed with the Division of Revenue before the business license is issued, or a Department of Labor certificate showing qualified self-insurer status. The policy number and a digital copy are also uploaded with the Contractor Registration application, alongside the Delaware unemployment insurance SUI number..
  5. 5Other. A certificate of notice from the Delaware Department of Labor confirming that the business has notified the Department that it has entered, or will enter, contracts to perform labor, or labor and materials, on a construction project in Delaware. The Division of Revenue may not issue the contractor business license without it..
  6. 6Other. A written safety plan compliant with Occupational Safety and Health Administration requirements, or evidence that one is being prepared, filed with the Contractor Registration application..
  7. 7Other. Gross receipts tax on construction receipts: a license fee of 0.6472 percent of aggregate gross receipts, with the first $100,000 per month exempt, due by the twentieth of the following month. A contractor whose receipts in the lookback period do not exceed $1,500,000 files quarterly with a $300,000 quarterly deduction, due on the last day of the first month after the quarter ends. Sums paid to licensed subcontractors under a written agreement are excluded from gross receipts and are reported on Form 1280. New licensees file quarterly through their first calendar year..
  8. 8Other. Compliance with the Home Improvement Services Regulation administered by the Department of Justice Consumer Protection Unit, in force since November 1, 2023. Every home improvement contract must be written and must contain all material terms, all final terms must be filled in before the homeowner signs, and the contractor must give the homeowner the Attorney General's two-page summary of consumer rights before signing. Contracts must state an approximate completion date unless they clearly disclose that none will be given, spell out express warranties and any clearly disclosed and initialed disclaimers, disclose cost-plus pricing with a good faith estimate, and disclose installment and delivery charges..
  9. 9Other. A New Castle County contractor license for work in the unincorporated county, which for a residential builder means a permit endorsed building contractor license. A new home builder must hold at least Class A, which carries a $150,000 statutory compliance bond and a maximum project valuation of $200,000, and must file a letter from a county-approved warranty company agreeing to warrant every new home built under the license; Class U is unlimited with a $200,000 bond. The 2026 fee is $410. Liability insurance of at least $250,000 per occurrence and $500,000 aggregate must name the county's Department of Land Use as certificate holder. No county examination applies. (if applicable).
  10. 10Other. Separate Delaware trade licenses where the work calls for them. Neither the business license nor the contractor registration authorizes licensed trade work: electricians are licensed by the Board of Electrical Examiners, plumbers and HVACR contractors by the Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners, and elevator mechanics, manufactured home installers and home inspectors by their own boards, all within the Division of Professional Regulation. A builder meets these by employing or subcontracting to the correctly licensed firm. (if applicable).

Issued by Delaware Division of Revenue (business license) and Delaware Department of Labor, Office of Contractor Registration

Delaware does not license residential contractors on skill. There is no state examination, no experience requirement, no financial statement, no qualifying individual and no board: the Division of Professional Regulation runs 37 boards and none of them covers general contractors, building contractors, residential contractors or home builders. Two credentials are still mandatory, and both are held by the business rather than by a person. The first is the contractor business license from the Division of Revenue, and it is worth being blunt about what that is: it is a tax registration. The Division's own guidance says the business license 'is not a regulatory license and the issuance of such license does not attest to the qualifications of the applicant to perform the activity described on such license.' It costs $75 a year and brings with it a gross receipts tax on construction receipts. The second is the Contractor Registration Certificate from the Department of Labor's Office of Contractor Registration under the Delaware Contractor Registration Act, which every business doing construction services or maintenance must hold before work begins; it checks workers' compensation coverage, a state business license, an OSHA-compliant safety plan and a disclosure of labor law violations and fraud convictions, but it tests nothing. What does govern residential work is the Department of Justice's Home Improvement Services Regulation, in force since November 1, 2023, which controls contracts and sales practices rather than competence. Local licensing is the real variable: unincorporated New Castle County licenses building contractors in classes by project value, while Kent and Sussex counties require permits only.

How local licensing works in Delaware

New Castle County. The Department of Land Use licenses contractors working in unincorporated New Castle County, and this is the closest thing Delaware has to a building contractor license. A permit endorsed license is required of anyone whose construction activity needs a permit, including building contractors; a non-permit endorsed license covers NAICS Sector 23 construction activity that needs no permit. Electrical contractors are excluded because they hold the state electrician license instead, as are businesses solely engaged in subdivision and land development, DelDOT right-of-way heavy utility work and maintenance employees of state-owned facilities. Permit endorsed building contractor licenses are graded by project value and backed by a surety bond on the county's own unmodified form: Class C up to $50,000 with a $25,000 bond, Class B up to $100,000 with a $50,000 bond, Class A up to $200,000 with a $150,000 bond, and Class U for unlimited value with a $200,000 bond. A new home builder must be licensed at Class A or above and must supply a letter from a county-approved warranty company confirming it will warrant every new home built under the license; a HUD-approved manufactured or modular home installer must be at least Class B with the same warranty proof. The application also needs a current Delaware business license (a temporary resident or non-resident contractor license from the Division of Revenue is accepted), a certificate of liability insurance of at least $250,000 per occurrence and $500,000 aggregate naming NCC Department of Land Use License Processing as certificate holder, and an optional authorized agents form. The 2026 fee is $410, made up of a $400 license fee and a $10 ICC digital code access fee. There is no county examination and no experience review; the class is set by bond and project value. Apply online through the county's licensing pages; Department of Land Use, 87 Reads Way, New Castle, (302) 395-5420, [email protected]. Use the county parcel search first, because incorporated towns are outside county jurisdiction.

Kent County. Levy Court issues building permits and publishes project-specific requirement sheets for single-family dwellings, decks, accessory structures and the like. It publishes no county contractor license, and the only credential it references is the state electrical license. Planning Services, (302) 744-2451.

Sussex County. 'All construction in Sussex County, whether new, remodeling or additions, requires a Sussex County issued building permit', and the county permit is required whether the property lies in a municipality or in the unincorporated county. Plans are reviewed for commercial buildings and are not required for detached single-family homes; projects disturbing 5,000 square feet or more need a Sediment and Erosion Control Plan. The county publishes no contractor license. Building Permit Office, Georgetown, (302) 855-7720.

Wilmington and other municipalities. A business operating inside Wilmington needs a city business license in addition to the state one, and the city's permit rules refer to work being done by a City of Wilmington license holder, so ask the Department of Licenses and Inspections what your trade needs before you contract there. Wage/Business License Division (302) 576-2415; permits, [email protected] or 302-576-3050. Other incorporated towns set their own business license rules, so check each one.

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.
