Kentucky to Delaware: residential contractor license reciprocity

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

Kentucky 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).

How Delaware licenses residential contractors

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 Kentucky has nothing to transfer

Kentucky residential contractor · “Building or residential contractor license or registration (city- or county-issued)”

Licensed by cities and counties

Verified September 17, 2026· 14 sources

Issued by No state authority; cities and counties license or register residential building contractors

Kentucky issues no statewide residential building, home builder or home improvement contractor license, so an out-of-state residential builder has nothing at state level to transfer and no state reciprocity to apply for. What Kentucky does license is the trades: the Department of Housing, Buildings and Construction (HBC) says on its own home page that it "licenses/certifies plumbers, electricians, boiler contractors, sprinkler and/or fire alarm contractors and building inspectors", and its administrative regulations in Title 815 add heating, ventilation and air conditioning licensing, elevator safety, boilers and pressure vessels, manufactured homes and home inspectors. Anyone self-performing plumbing, electrical, HVAC, boiler or fire-protection work in Kentucky needs the matching HBC license whatever the local building rules say, and that is where the state-level reciprocity conversation belongs. Housing work itself is licensed jurisdiction by jurisdiction and the rules differ sharply: Louisville Metro issues a Building Type A - Residential contractor license with six hours of continuing education before each renewal, Lexington-Fayette registers a "general contractor, residential only" class under its Contractors Registration Ordinance, and the joint Bowling Green - Warren County Contractors Licensing Board issues a General Contractors License for remodeling and building. Owensboro and Covington sit at the other end: neither publishes a contractor competency license at all, and a builder there files an occupational business license and carries insurance instead. None of these credentials involves a trade or business-law exam, and none of them gives any weight to a license held in another state, so the practical work is registering in each place where permits will be pulled and carrying the insurance each one demands.

How local licensing works in Kentucky

How local licensing works. No Kentucky agency licenses residential builders or remodelers, and there is no state qualifying party, no state exam and no state reciprocity for this work. Each city and county decides for itself, so identify the building department with jurisdiction over the address before applying anywhere. A credential issued by one Kentucky jurisdiction does not carry into the next one, and none of the jurisdictions below grants anything for a license held in another state. Two statewide obligations apply wherever the project is: the HBC license for any self-performed plumbing, electrical, HVAC, boiler or fire-protection work, and compliance with the Kentucky Building Code adopted in 815 KAR Chapter 007.

Louisville Metro (Jefferson County). The Office of Construction Review issues the contractor licenses for the merged city-county. A builder chooses a term and then a scope. License A "lets you work on one or more permitted projects during a calendar year, which runs from January 1st to December 31st"; License B "allows you to work on only one permitted project during a calendar year." The scopes are Building A-Residential, Building A-Residential/Commercial, Building A-Commercial and Building B. Building Type A costs $125 a year and Building Type B $50 per permit, and "only one Building Type B license will be granted per person/company per renewal year." Six continuing education credit hours from a pre-approved list are required before renewal for Building A-R, Building A-RC and Building B, which is to say for everyone whose scope touches houses. The filing is a certificate of liability insurance naming the Office of Construction Review as certificate holder, workers' compensation and unemployment insurance or a signed and notarized affidavit that neither applies, an Occupational License Number from the Revenue Commission of Jefferson County on (502) 574-4860, and the application itself through the Metro business portal. Annual renewals must arrive with current liability insurance, the continuing education records for residential contractors, a workers' compensation form and a subcontractor list, and "any missing items will result in ALL items being returned." There is no exam, no experience requirement and no bond on the building categories; only the wrecking classes carry a written exam, a surety bond and a year of supervisory experience. Office of Construction Review, 444 S. 5th St., Suite 100, (502) 574-3321.

Lexington-Fayette Urban County. The Division of Building Inspection runs a Contractors Registration Ordinance: "this ordinance requires all contractors to register with the Building Inspection" and "unregistered contractors cannot obtain building permits." There are three classes under Ordinance 5-90(a). A general contractor, residential only "constructs up to 4-family homes (4-Plex), performs home remodeling, and may supervise, arrange, and/or perform more than two unrelated building trades or crafts." A general contractor covers everything larger. A specialty contractor "performs commercial, industrial, public works and residential construction and specializes in two or fewer unrelated building trades or crafts." Registration takes four steps: a $10 Home Office Certificate or a $25 Certificate of Occupancy if the business address is in Fayette County; an occupational business license from Revenue at 218 E. Main St., 2nd floor, (859) 258-3340; general liability insurance and workers' compensation with LFUCG as certificate holder, or the "Workers Comp Exempt" declaration on the application if neither applies; and the online Contractor Registration Application through the city's permitting portal with the occupational license and certificate of insurance uploaded. No exam, experience or bond is required for any of the three classes. The division's published fee schedule prices permits rather than registrations and lists no contractor registration fee, so ask Building Inspection for the current amount before filing. 101 E. Vine St., (859) 258-3770, [email protected].

Bowling Green and Warren County. A single joint Contractors Licensing Board licenses for both the city and the county under Ordinance 91-58 WC and Ordinance 91-25 BG. A General Contractors License is needed by anyone "doing any type of general contract work in Bowling Green / Warren County including pulling permits for building or remodeling, construction management, or if you would have two or more subcontractors per job", and costs $250. A Specialty Contractors License covers subcontract work or a job with at most one subcontractor, and costs $100. Both fees are non-refundable and renewals are annual, pro-rated for a mid-year filing. The filing is the application plus a certificate of insurance naming the board as certificate holder, with "a minimum requirement for General Liability Insurance [of] $100,000 per occurrence", workers' compensation coverage shown on the certificate or a notarized Affidavit of Exemption, and a notarized Partnership Agreement for a partnership. Licenses are non-transferable and "any change in ownership nullifies previous licenses." There is no exam and no experience review, and the board says so directly: "the Contractors Licensing Board does not warrant that you are otherwise qualified to perform your trade or specialty by the issuance of its license." A Bowling Green occupational license is also needed for work inside the city limits and a Warren County occupational license for work outside them. Contractors Licensing Board, 1141 State Street, Suite 200, 270-781-3530.

Owensboro and Daviess County. There is no Owensboro contractor license. The Owensboro Metropolitan Planning Commission's Building & Electrical Division "issues all building and electrical permits required by the Kentucky Building Code and National Electrical Code" for Owensboro-Daviess County, along with HVAC, sign and parking lot permits and certificates of occupancy, and it issues no contractor credential of any kind. What a builder needs instead is the city's business registration: "any person, partnership, corporation, or other legal entity must register with the Occupational License Division prior to conducting business inside the city limits", with "a minimum license fee of seventy-five ($75.00) dollars due with registration." New construction draws at least three field inspections - footer and foundation, framing and final - before a certificate of occupancy issues. Occupational License Division, 101 East 4th Street, 270-687-5600.

Covington and Kenton County (Northern Kentucky). Planning and Development Services of Kenton County is the building department for Covington and the surrounding communities, and its rule is short: "when completing work within Kenton County, all contractors must obtain and maintain a Kenton County occupational license and provide proof of Kentucky workers' compensation insurance coverage. In addition, the Kentucky Department of Housing, Buildings, and Construction requires a license for electrical, HVAC, plumbing, and fire suppression work. Contractors must provide copies of all these items before any permits can be issued." There is no residential builder license, exam or bond. In Covington itself a zoning permit from the city, and a certificate of appropriateness where a historic preservation overlay applies, must come before PDS will issue the building permit. PDS, 1840 Simon Kenton Way, Suite 3400, Covington, 859-331-8980; building permits 859-957-2408.

Storm-damaged communities. The Attorney General's Office of Consumer Protection runs joint emergency contractor registration programs with the City of Mayfield and Graves County, the City of Princeton and Caldwell County, the City of Dawson Springs and Hopkins County, and the City of Bremen and Muhlenberg County, "to register contractors looking to assist storm victims." The program "requires contractors to register prior to doing business", and registrants are issued placards that must be displayed on the job site and in the vehicle. It is a consumer-protection registration aimed at transient storm-chasers rather than a skill license, and it applies only in those communities. Details on (502) 871-2424.

Everywhere else. The remaining Kentucky cities and counties each set their own rules, from a full licensing board like Bowling Green's to nothing beyond an occupational license and proof of insurance. Ask the local building department what it requires before bidding, and expect to repeat the filing in each jurisdiction.
