Kansas to Washington: residential contractor license reciprocity
Kansas does not issue a statewide residential contractor license, so there is nothing to transfer. Here is Washington'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 registers the same way; an out-of-state contractor license transfers nothing
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
A residential contractor licensed in another state registers in Washington exactly as a first-time applicant does, and holding that license neither helps nor hinders the application. L&I does not review, verify or credit out-of-state credentials for contractor registration, and it cannot waive anything, because there is nothing to waive: Washington's Contractor Registration Act and its rules impose no examination, no experience requirement and no competency test, and neither the statute, the rules nor the application form mentions reciprocity or another state's license. Washington also does not participate in the NASCLA Accredited Examination program, since it holds no contractor examination for that examination to replace. The steps are the same for an applicant from Idaho, from Florida or from down the street: file a Business License Application with the Department of Revenue for a UBI number (and file with the Secretary of State first if the business is a corporation, LLP or LLC), buy a continuous contractor surety bond of $30,000 for a general registration or $15,000 for a specialty registration, or assign a savings account for the same amount, buy general liability insurance naming L&I as certificate holder, complete and notarize the Application for Construction Contractor Registration (F625-001-000) with a notarized affidavit from every principal, and pay $150.20. The bond, the insurance certificate and the application must all carry the exact business name registered with the Department of Revenue. Registration lasts two years and renews for $150.20.
The 3-4 week figure is L&I's published processing time for applications sent by mail; applications completed in person at a local L&I office are handled at the counter, and the registration card follows in about two weeks either way. The only out-of-state accommodation anywhere in the registration statute is unrelated to skills: RCW 18.27.030(1)(c)(iii) lets an applicant domiciled in a state or Canadian province covered by an extraterritorial workers' compensation agreement file that jurisdiction's certificate of coverage instead of opening a Washington industrial insurance account. L&I's out-of-state specialists can be reached at [email protected] or 360-902-4817. Registration does not cover the licensed trades: a contractor whose crews do plumbing, electrical, elevator, boiler, asbestos or mobile home installation work needs the separate trade license or certification for that work as well.

What you must already have
- Every owner, member, partner and corporate officer must be at least 18 and provide a Social Security number or individual taxpayer identification number, a government-issued photo ID number and a residential address, and must sign the application before a notary public.RCW 18.27.030(1)(a) and (g); the age and notarization requirements are stated in the instructions to form F625-001-000. Falsifying the application carries a fine of up to $10,000 and can lead L&I to deny or revoke the registration.
- The application is denied if a principal has an unsatisfied final judgment for work subject to chapter 18.27 RCW, or owes certain unpaid debts to L&I, or if the business is a successor to a previously registered entity with such a judgment or debt. The application asks whether the applicant, a spouse or registered domestic partner, or anyone with common ownership, management or control has ever been registered as a contractor in Washington.
- Washington asks for no trade experience, apprenticeship hours, education or examination result, so documented years of homebuilding in another state neither shorten nor replace any step.
What you'll do to get licensed in Washington
- 1Application fee. Pay the application fee ($150.20). Contractor registration issuance fee (WAC 296-200A-900(1)). The registration is valid for two years from issuance and renews for the same $150.20; reinstatement after a suspension costs $70.90 and a duplicate registration certificate costs $16.50. Pay by check or money order if applying by mail, or by cash, check, money order or credit or debit card in person at a local L&I office..
- 2Surety bond. Post a surety bond ($30,000). Continuous Contractor's Surety Bond (F625-003-000) naming the State of Washington as obligee, issued by a surety insurer authorized under chapter 48.28 RCW: $30,000 for a general contractor registration, or $15,000 if you register in a single specialty trade. The original signed and sealed bond must be filed with L&I, or the surety may file it through L&I's electronic bond and insurance policy system. An assigned savings account, certificate of deposit, time deposit or money market account at a bank, savings and loan or credit union with a Washington branch (form F625-008-000) may be posted instead. The amount steps up for a contractor with final judgments involving a residential single-family dwelling in the previous five years: for a general registration $40,000 after one judgment, $60,000 after two and $90,000 after three or more (specialty registrations $20,000, $30,000 and $45,000). Cancellation of the bond automatically suspends the registration..
- 3Insurance. Carry the required insurance ($250,000). General liability insurance of $200,000 public liability and $50,000 property damage, or a $250,000 combined single limit policy, written in the exact business name with L&I named as certificate holder. The original certificate must reach L&I by mail, through the designated insurance agent portal or in person at a service location; L&I does not accept certificates by email or fax. An assigned account in the statutory amounts may be filed instead as proof of financial responsibility (RCW 18.27.050(3)). Cancellation or expiry of the policy automatically suspends the registration..
- 4Business license. Obtain a business license. A Washington Business License Application filed with the Department of Revenue Business Licensing Service, producing the nine-digit Uniform Business Identifier (UBI) that goes on the contractor registration application; the UBI must stay active and valid for as long as the registration is held. A corporation, limited partnership, LLP or LLC, including one formed in another state, files with the Secretary of State first. L&I will not process the registration until it confirms that the business license application has been filed and an excise tax account is open. The Department of Revenue's application fee varies with the endorsements the business needs and is not published as a single figure; see dor.wa.gov for the current processing fee..
- 5Other. Notarized Application for Construction Contractor Registration (F625-001-000), with an individually notarized affidavit of signature from each owner, member, partner and corporate officer. Signatures must be original, so L&I cannot accept a copy or an emailed application; it is filed in person at a local L&I office or mailed to Contractor Registration, PO Box 44450, Olympia WA 98504-4450 together with the bond, the insurance certificate and the fee..
- 6Other. Workers' compensation coverage and an employment security department number if the business will have employees, opened through the Department of Revenue; a business with no Washington employees may substitute its UBI account number. An applicant domiciled in a state or Canadian province with an extraterritorial coverage agreement may instead file that jurisdiction's certificate of workers' compensation coverage (RCW 18.27.030(1)(c)(iii)). An employer identification number is needed from the IRS unless the applicant is a sole proprietor with no employees..
- 7Other. Model Disclosure Statement, Notice to Customer (F625-030-000), which the contractor must give the customer on every residential job of $1,000 or more and on commercial projects of $1,000 to $60,000. The registration number must also appear on all business communications, including business cards, advertising, estimates and bid proposals..
- 8Other. Separate trade licensing where the work calls for it. Contractor registration does not authorize plumbing, electrical, elevator, boiler, asbestos or mobile home installation work; each of those carries its own education, examination and licensing requirements under its own chapter, and electrical work is licensed under chapter 19.28 RCW rather than as a registration specialty. Lead-based paint work in pre-1978 housing is administered by the Washington State Department of Commerce and pesticide application by the Washington State Department of Agriculture. (if applicable).
Published fees on this path total $150.20, excluding exam-vendor fees, bonds, and insurance.

How Washington licenses residential contractors
Washington residential contractor · “General Contractor Registration (or a Specialty Contractor Registration)”
Statewide license
Issued by Washington State Department of Labor & Industries, Contractor Registration
Washington does not license residential building contractors. It registers every construction contractor with the Department of Labor & Industries, and registration is the only credential a homebuilder or remodeler needs: there is no trade examination, no business-and-law examination, no experience or apprenticeship requirement, no financial statement and no named qualifying party anywhere in chapter 18.27 RCW or chapter 296-200A WAC. The same registration covers houses and commercial buildings, because Washington's two classifications divide work by the number of trades rather than by market. A General contractor registration is for a business whose work uses more than one building trade on a single job or under a single building permit, and it covers residential and commercial work alike; a Specialty contractor registration limits the business to one of 63 named trades such as roofing, framing and rough carpentry, siding, drywall or HVAC. L&I's own application makes the point explicitly: it asks whether you will do commercial, residential or both, then says the question is 'for statistical reasons and you will not be held to the type you choose.' A developer who subdivides land for residential purposes or builds one or more residential units needs the general registration, and there is no separate homebuilder, residential builder or home improvement credential above or below it. The registration belongs to the business rather than to a person, so a builder moving to Washington registers the sole proprietorship, partnership, corporation or LLC that will sign contracts; every owner, member, partner and corporate officer signs the application before a notary and provides a Social Security number or ITIN, and each must be at least 18. What Washington requires instead of qualifications is financial protection for the customer: a Uniform Business Identifier from the Department of Revenue, a continuous $30,000 surety bond for a general registration or $15,000 for a specialty registration, general liability insurance of $200,000 public liability and $50,000 property damage or $250,000 combined single limit, and a $150.20 fee for a two-year registration.
Why Kansas has nothing to transfer
Kansas residential contractor · “Residential contractor license (Class C in most Kansas jurisdictions)”
Licensed by cities and counties
Issued by No state authority; cities and counties license residential contractors
Kansas issues no statewide residential builder, home builder or home improvement contractor license, and it has no state contractor board or state contractor exam. Cities and counties license builders instead, and most of the larger ones use the same shape: a company-held license qualified by a named person, in classes lettered A for unlimited work, B for buildings up to three stories and C for houses and duplexes. What the legislature did do is standardize the test. K.S.A. 12-1556 designates a set of standard examinations for 'general contractors, building contractors and residential contractors', and K.S.A. 12-1557 requires any Kansas city or county that licenses builders to set a 75 percent passing score, to charge a uniform examination fee and to accept the resulting certificate of competency 'without additional examination' anywhere else in the state that licenses contractors. In practice that means the credential Kansas jurisdictions care about is a passing score on the ICC Kansas contractor examination series - 550 for the Class A general building contractor, 551 for Class B and 552 for Class C residential - rather than a license held anywhere else. A residential builder moving to Kansas therefore has no state license to transfer and nothing to reciprocate into; the practical work is sitting the Kansas standard examination once, then licensing the business in each place where it will pull permits. The state does license two things a residential builder touches: roofing contractors, who must register with the Kansas Attorney General under the Kansas Roofing Registration Act before selling roofing services for a fee, and mobile home installers.
How local licensing works in Kansas
How local licensing works. Every Kansas contractor license is issued by a city or a county, and the license belongs to the company rather than to the person; the company names a qualifying individual or qualifying party who supplies the examination result or degree, and losing that person usually inactivates the license. Two state statutes shape what the jurisdictions may ask. K.S.A. 12-1557 caps the examination at the designated standard test, sets the passing score at 75 percent, and makes the certificate of competency from that test valid for licensure 'without additional examination' in any other Kansas county or city that licenses contractors. K.S.A. 12-1558 lets a jurisdiction use a different examination instead, but a license granted on a non-standard examination does not authorize work outside that jurisdiction 'except when authorized by reciprocal agreement between the political subdivisions involved' - so the only contractor reciprocity Kansas law contemplates is between Kansas cities and counties, never with another state. None of the jurisdictions below gives any credit for a contractor license issued outside Kansas.
Johnson County (Overland Park, Olathe, Lenexa, Leawood, Shawnee and the rest of the county). Johnson County Contractor Licensing, a division of Planning, Housing and Community Development, issues and tracks eleven license types for the whole county. Building permits are issued by Johnson County Building Codes in the unincorporated county and by each city elsewhere, and the county's own application states the rule plainly: 'When a building permit is issued in the company/firm's name, the company/firm must comply with Johnson County Contractor Licensing Regulations (Resolution 076-24) and be subject to the jurisdiction of the Johnson County Contractor Licensing Review Board.' The residential class is Class C, which 'shall entitle the holder thereof to construct, remodel, repair, and demolish single-family or duplex residences and buildings accessory thereto', including framing, roofing, swimming pool construction, non-structural remodeling and repairs, but not HVAC, plumbing, electrical or fire protection work, which need the separate DM, DP, DE and DF or DFA licenses. Qualification is ICC exam 552 or KGC, Standard Residential Building Contractor, at 75 percent or better, or a Bachelor of Science or higher in architecture, relevant engineering, construction science or construction management from an ABET or ACCE accredited program. The company must designate a qualifying individual who works at least 30 hours a week for it, and every qualifying individual needs eight hours of approved continuing education a year for the company to renew. Insurance is $1,000,000 combined single limit per occurrence plus $1,000,000 completed operations, with the county named as certificate holder and 30 days' notice of any reduction, plus workers' compensation with $100,000 employer's liability or a notarized waiver if there are no employees. A Certificate of Good Standing is needed from the Secretary of State where the company is registered. Fees are a $100 application fee plus $225 per license type, so a single new license is $325; renewal is $225 per type with a $75 late fee from February 1. New applications cannot be filed online. Licenses are valid for one year. 111 S. Cherry Street, Suite 1000, Olathe; 913-715-2233 option 1.
Wichita and Sedgwick County. The Metropolitan Area Building and Construction Department licenses contractors for unincorporated Sedgwick County, the City of Wichita and the small cities it serves, and its position on outside credentials is explicit: 'MABCD does not reciprocate with other jurisdictions.' The residential general class is Class C - Residential, and there is also a Class D Residential Maintenance license; general contractor licenses run two years and expire on December 31 of each even year, with a grace period to January 31. The qualified person must produce 'a copy of Kansas Standard ICC exam' with a score of 75 percent or better, and must file an ICC test release form if the examination was taken outside Kansas. Two-year license fees are $1,000 for Class A, $600 for Class B, $450 for Class C Residential and $360 for Class D Residential Maintenance, roofing, siding, roofing and siding, swimming pool, wrecking, cell tower, fire sprinkler and 'not otherwise classified'; a new application costs an extra $50, and late renewal adds 25 percent in February and 50 percent after that. The filing also needs liability insurance of at least $300,000 naming MABCD as certificate holder in the exact company name, a workers' compensation certificate or a notarized waiver, an auto certificate or a notarized waiver, a Certificate of Good Standing from the Kansas Secretary of State unless the applicant is a sole proprietor, a qualified person declaration page, a company officers signature page and a letter authorizing the qualified person to bind the company in contracts. Roofing applicants must show their Kansas Attorney General roofer registration number. Review takes up to two weeks. 271 W. 3rd, Suite 101, Wichita; 316-660-1840, by appointment.
Kansas City, Kansas and Wyandotte County. The Unified Government works differently from the rest of the state: it does not run a competency license for builders. 'General contractors and subcontractors are required to obtain a city occupational tax license (Business License) if working within Wyandotte County', which is handled by Business Licensing on (913) 573-8780, while 'trade masters are required to carry a master's license with Building Inspections', earned on a Prometric or equivalent standard examination and administered through the Neighborhood Resource Center. A remodeler or homebuilder working in Kansas City, Kansas therefore registers and pays the occupational tax rather than qualifying a person, and makes sure the electrical, mechanical and plumbing scope is performed by licensed masters. Building Inspection and the License Department are both at 4601 State Avenue, Indian Springs Marketplace; Building Inspection (913) 573-8620.
Topeka. The Development Services Division 'is responsible for issuing all contractor and trade licenses in the City of Topeka', and 'all trades are required to be licensed and pull permits to work in City of Topeka.' The residential class is Class C, qualified by ICC exam 552, the Kansas Standard Residential Building Contractor examination, at 75 percent or better; Class B uses exam 551 and Class A exam 550. Topeka will also accept results from Prometric, Thomson-Prometric, Experior, NAI-Block and Block at 75 percent or better, subject to review, or an official transcript for at least 30 hours of coursework from an accredited school in construction science, engineering or architecture, in which case the degree holder becomes the qualifying party and must work for the company full time. The application is filed with the exam or educational certification, a qualifying party verification form, the Renovate Right form, a general liability certificate and a workers' compensation certificate or notarized affidavit, all naming City of Topeka Development Services, 620 SE Madison Unit 6, as certificate holder; processing takes up to ten days. Class A, B and C holders need eight hours of continuing education a year, licenses renew by December 14 each year, fees are not prorated, a lapse in the insurance certificate costs $30 to reinstate after a 30-day grace period, and an unreported address change costs $10. Roofers must supply their Kansas Attorney General roofer registration certificate number before Topeka will license them. The city does not publish its general contractor license fee online - ask Development Services on 785-368-3905 for the current amount before applying.
Lawrence. Chapter 5, Article 15 of the City Code requires a Lawrence contractor license before anyone may 'undertake or perform any action in the City for which a Building Permit is required.' The residential class is Class C, Residential Contractor, covering any permitted work 'on any detached dwelling or duplex'; Class B covers structures up to three stories and Class A everything. Class C needs two years of qualifying experience performing Class C work, or a valid Class D license plus four years as a licensed Class D contractor, and experience claims must be verified by a licensed contractor, building official, architect or engineer. Competency is shown by a certificate of competency from a nationally recognized testing institution of the kind contemplated by K.S.A. 12-1556, by a bachelor's degree in engineering, architecture or construction science, or 'an equivalent Contractor License from another jurisdiction with whom the City has an existing and valid reciprocity agreement' - the ordinance provides for such agreements but names none, so ask Building Inspections whether one covers your jurisdiction before relying on it. Fees are a $75 application fee for each applicant and each qualifying party plus a $75 annual license fee. Insurance is commercial general liability of not less than $1,000,000 per occurrence including completed operations, written by a Kansas-licensed insurer, plus workers' compensation. The Building Official decides within 30 days. The license is company-held, each qualifying party must be a principal or an employee working more than 30 hours a week, and any change of company name, ownership or qualifying party voids the license and requires a new one. Renewal needs eight hours of construction-related continuing education a year for every qualifying party, all delinquent fees paid and all inactive open permits closed or extended. Separate Class E licenses cover mechanical, plumbing, electrical and fireplace work, and those trades also need certified master or journeyman tradespeople. (785) 832-7700.
Everywhere else. Kansas has hundreds of other cities and counties, each free to license builders, to license only the trades, or to require nothing beyond a permit and proof of insurance. Find the building department with jurisdiction over the address and ask before you bid. Two obligations follow you across the whole state whatever the local answer: register with the Kansas Attorney General before providing roofing services for a fee unless you qualify as an exempt general contractor, and hold or employ the right trade credentials for any electrical, plumbing or mechanical work.
