Missouri to Washington: general contractor license reciprocity
Missouri does not issue a statewide general 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.

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 commercial or general contractor licensed in another state gains nothing from that license in Washington and loses nothing by not having one. L&I does not evaluate out-of-state credentials for contractor registration, publishes no reciprocity or endorsement route, and has nothing to waive, because Washington holds no contractor examination and sets no experience requirement. Washington is not one of the state agencies that accept the NASCLA Accredited Examination for Commercial General Building Contractors, for the same reason. An arriving contractor therefore follows the ordinary route: file a Business License Application with the Department of Revenue for a UBI (after filing with the Secretary of State if the business is a corporation, LLP or LLC, including one formed in another state), file a continuous $30,000 contractor surety bond or an assigned savings account for that amount with the State of Washington as obligee, file a certificate of general liability insurance naming L&I as certificate holder, submit the notarized Application for Construction Contractor Registration (F625-001-000) with a notarized affidavit from every principal, and pay $150.20 for a two-year registration. The business name must match exactly across the application, the bond and the insurance certificate. Applications mailed to Olympia take about three to four weeks to process; applications completed at a local L&I office are handled at the counter, and the registration card arrives about two weeks later.
An out-of-state business should also contact L&I's extraterritorial specialists at [email protected] or 360-902-4817 about reporting hours worked in Washington: L&I has workers' compensation reciprocal agreements with several neighboring states, but those agreements are about industrial insurance rather than licensing, and the construction industry is carved out of some of them. The statutory bond is a consumer-protection device, not a measure of capacity, so a large commercial contractor may still need far higher bonds by contract or under the public works statutes; the figures here are only what registration requires. Public agencies may not contract with an unregistered contractor (RCW 18.27.111).

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), with the age and notarization requirements stated in the instructions to form F625-001-000.
- 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 operating with all or part of the assets of a previously registered entity under substantially common ownership, management or control that has such a judgment or debt.
- No examination result, trade experience, education, apprenticeship or financial statement is asked for at any point, so an out-of-state license, a NASCLA examination transcript and documented years in business are all equally irrelevant to the decision.
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 certificate costs $16.50. L&I mails a renewal notice no more than 45 days before expiry, and it is the contractor's duty to notify the department in writing within ten days of any change of address..
- 2Surety bond. Post a surety bond ($30,000). Continuous Contractor's Surety Bond (F625-003-000) in the sum of $30,000 for a general contractor, issued by a surety insurer meeting chapter 48.28 RCW and naming the State of Washington as obligee. The original, uncorrected bond must be filed with L&I with the bonding company's seal, or filed electronically by the surety, and it must carry the exact business name on file. An assigned savings account for the same amount (form F625-008-000) held at a bank, savings and loan or credit union with a Washington branch may be posted instead. The bond answers claims by workers, the state for taxes and contributions, suppliers and customers; cancellation suspends the registration automatically, and a contractor that switches from a general to a specialty registration may not reduce the bond amount for two years..
- 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 statute states it as $50,000 for property damage, $100,000 for injury or death to any one person and $200,000 for injury or death to more than one person. Certificates reach L&I by mail, through the designated insurance agent portal or in person, never by email or fax, and an assigned account in the statutory amounts may be filed instead as proof of financial responsibility. Cancellation or expiry 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) required on the registration application and required to stay active and valid throughout. A corporation, limited partnership, LLP or LLC formed in another state registers with the Washington Secretary of State first, and a copy of the Secretary of State certificate is filed with L&I. L&I will not process the registration until it verifies 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. All signatures must be original, so a copy or an emailed application is not accepted; file it in person at a local L&I office or mail it to Contractor Registration, PO Box 44450, Olympia WA 98504-4450 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 in Washington; a business with no Washington employees may substitute its UBI account number. An applicant domiciled in a state or Canadian province covered by an extraterritorial workers' compensation agreement may file that jurisdiction's certificate of coverage instead of opening a Washington industrial insurance account (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), required on every residential job of $1,000 or more and on commercial projects of $1,000 to $60,000; failing to give it can cost the contractor its lien rights. The registration number must appear on all business communications, including advertising, bids, estimates and business cards, and a city, town or county may not issue a building permit without verifying that the contractor is registered..
- 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 carries its own education, examination and licensing requirements, and electrical contracting is licensed under chapter 19.28 RCW rather than as a registration specialty. A general contractor may meet these by subcontracting to, or employing, the appropriately licensed firm or certified tradesperson. (if applicable).
Published fees on this path total $150.20, excluding exam-vendor fees, bonds, and insurance.
What you'll need to buy or arrange
Surety bond
A license or contractor bond is bought from a surety, not the state. Price is a small percentage of the bond amount and depends on your credit.
- Surety bond · $30,000
Liability insurance
Some states require proof of general liability or workers' compensation coverage at licensing time.
- Insurance · $250,000
Business registration
If you plan to contract in your own name, budget for a business license or entity registration on top of the trade license.

How Washington licenses general contractors
Washington general contractor · “General Contractor Registration”
Statewide license
Issued by Washington State Department of Labor & Industries, Contractor Registration
Washington's unlimited tier is the General contractor registration issued by the Department of Labor & Industries, and it is the same credential described at the residential level: one registration covers both house and commercial work, because Washington draws no residential/commercial line. A general contractor is defined by trade breadth rather than by market or contract value: it is a contractor 'whose business operations require the use of more than one building trade or craft upon a single job or project or under a single building permit', including anyone who superintends or consults on such work, while a specialty contractor is limited to one of 63 named trades and may subcontract only work incidental to that trade. There is no dollar cap, no classification letter and no project-size tier on a general registration. Washington does not examine contractors at all: chapter 18.27 RCW and chapter 296-200A WAC contain no trade exam, no business-and-law exam, no experience requirement, no net worth or financial statement test and no qualifying party, and L&I's application asks for none of them. What the state requires is a registered business with money behind it, which the department verifies rather than judges: a Uniform Business Identifier from the Department of Revenue, a continuous $30,000 surety bond (or an assigned savings account for the same amount), general liability insurance of $200,000 public liability and $50,000 property damage or $250,000 combined single limit, a notarized application signed by every owner, member, partner and officer, and $150.20 for two years. Registration is required of every contractor with almost no threshold: the only general exemption is work on a single project whose total price for labor, materials and everything else is under $500, and even that is lost if the person advertises as a contractor. Registration is statewide and exclusive; RCW 18.27.130 bars any city or county from issuing its own contractor registration, license or bond, though a city may still charge a general business license fee and a gross receipts tax, and a building department must verify a contractor's registration before it issues a permit.
Why Missouri has nothing to transfer
Missouri general contractor · “Class A or B general contractor / construction business license (city-issued)”
Licensed by cities and counties
Issued by No state authority; cities and counties license or register commercial building contractors
Missouri has no statewide general, commercial or unlimited building contractor license, so there is nothing at state level for an out-of-state general contractor's license to transfer into and no NASCLA route to take, because Missouri is not a NASCLA participating state. Title XXII of the Revised Statutes, which contains every occupational licensing chapter, has no contractor or builder chapter, and the Division of Professional Registration regulates only one construction trade, electrical contractors. That voluntary statewide electrical contractor license under RSMo 324.900 to 324.945 is often mistaken for a general contractor credential; it is not. Its statutory definitions reach electrical contracting alone, and RSMo 324.925, which forces every city and county to honor it and bars them from testing a holder's proficiency, applies to electrical work only and expressly leaves local building regulation untouched. Commercial building is therefore governed city by city, and only one of Missouri's larger jurisdictions examines commercial builders: Independence issues Class A and Class B general contractor licenses to individuals on an ICC or Prometric score, a reciprocal license or a construction-related degree. Kansas City runs seventeen contractor license categories and none of them is a commercial building contractor - its own bulletin says a business license for construction "is the only city license required" for commercial building permits - and St. Louis City, St. Louis County, Springfield, Columbia and Jefferson City likewise license the trades and ask a commercial builder for nothing more than a business license.
How local licensing works in Missouri
How it works in Missouri. No Missouri agency licenses general, commercial or unlimited building contractors, and there is no state qualifying party, no state business-and-law exam and no NASCLA acceptance to rely on. Cities and counties control commercial construction through the building permit, and almost all of them regulate the electrical, mechanical, plumbing and fire trades rather than the builder. The one statewide rule worth knowing is RSMo 324.925: a political subdivision must recognize the state's voluntary electrical contractor license in place of its own and may not test that holder's electrical proficiency, on pain of having its local sales tax distributions withheld. The statute is limited to electrical contracting - it creates no equivalent obligation for builders, and it expressly preserves each subdivision's power to implement codes, require business licenses, issue permits and inspect work. So a general contractor arriving in Missouri qualifies separately in each jurisdiction, and the only genuinely portable credential is a passing score on a national contractor examination, which matters in exactly one of the places below.
Independence. The clearest commercial program in the state, and the only one of the seven that examines a commercial builder. The city licenses the individual rather than the business - "contractor licenses belong to the licensed individual, NOT a company" - and the general contractor license "covers framing, footings, and general construction" in three classes: Class A, residential and commercial; Class B, residential and commercial up to three stories; Class C, residential only. Qualification is ICC or Prometric test scores from within the last five years at 75 percent or better, or "a current, active license with a jurisdiction that we reciprocate with," which the city defines as "any jurisdiction that issues licenses in a similar fashion," or a bachelor's degree in engineering, architecture or construction science from an accredited college or university. Only a master license holder may apply for or be named on a building permit; journeymen may not. Licenses expire December 31 annually with no proration, and a business license is required in addition. [email protected], (816) 325-7401.
Kansas City. City Planning & Development enforces Article XII of the Kansas City Building and Rehabilitation Code through seventeen categories of contractor license - demolition, electrical, elevator, fire protection, gas-fired appliance, mechanical, pipe fitting, plumbing, residential building and sign - and there is no commercial or general building category among them. The city says so directly in its residential licensing bulletin: "a Business License for Construction is the only city license required for a contractor performing swimming pool construction, uncovered deck construction, retaining walls, non-structural remodeling, installation of roof mounted solar panels with no or limited structural work, and commercial building permits." A commercial builder therefore buys the business license from the Finance Department, keeps a current Missouri Secretary of State registration, and makes sure each licensed trade on the job holds its own Kansas City contractor license and employs a certificate-of-qualification supervisor. Where the general contractor self-performs a regulated trade, the full route applies: a $60.00 certificate application with notarized reference letters and a recognized exam score, applicant at least 21 with a high school diploma or GED and documented experience, then a $60.00 application and $181.00 issuance fee for the company license, renewed quadrennially at $181.00. [email protected], (816) 513-1500.
St. Louis City. The Building Division runs four boards of examiners - the Committee of Electrical Examiners, the Mechanical Contractors Board of Examiners, the Plumbers and Drainlayers Board of Examiners and the Sprinkler System Contractors Board of Examiners - and none of them covers building contractors. A commercial general contractor takes out a construction or contracting business license from the License Collector: state tax number, application, clearance from the Collector of Revenue, an occupancy permit from the Building Division, and proof of workers' compensation coverage or a signed statement that it is not legally required. "All general contractors are required to furnish a list of the sub-contractors on any job to the License Collector." There is no exam, bond or experience review. Building Division, City Hall Room 425, 1200 Market St., (314) 622-3313.
St. Louis County. "The County does not license general contractors." It "does verify that out-of-state contractors are registered with the state," and it "does register all repair contractors that obtain permits for repairs from a natural disaster such as a flood or severe storm." Its licensing effort goes into the trades: electrical, mechanical (four contractor categories under the county Mechanical Code, chapter 1108 SLCRO) and plumbing, each with a licensing board, and "the County only issues trade permits to licensed contractors." Commercial permits for unincorporated county land come from Transportation and Public Works at 41 South Central Ave., 6th Floor, Clayton, 314-615-5184; inside the county's many municipalities, check the city's own building department too.
Springfield. A permit will not issue until "a City-licensed General Contractor (GC) or Trade Master (TM)" is named on it, so the general contractor credential is compulsory - but it is a business license from the License Division rather than a tested qualification. The city's examining program covers electricians, plumbers, gas fitters and mechanical craftsmen only, who must be "tested and certified to afford competence and knowledge of the codes" and who may present an identical Prometric, Experior, Block or ICC examination passed at 75 percent or better in another jurisdiction. Contractors file proof of workers' compensation or sign a notarized exemption statement. Permit desk 417-864-1585; License Division 417-864-1617.
Columbia. Building and Site Development certifies trades only - Trade Apprentice, Electrical, Mechanical and Plumbing - with tests "administered by a private testing firm according to a regular schedule," and the city maintains boards of electrical, plumbing and mechanical examiners but none for builders. A commercial contractor holds a city business license at $0.25 per $1,000 of gross receipts, minimum $75 and maximum $10,000 a year, plus a $45 application fee, and files a certificate of workers' compensation insurance if it has one or more employees. Business License Division 573-874-7378.
Jefferson City. "All contractors performing work in Jefferson City must have a local license," but only "electrical and plumbing contractors and their employees are required to obtain specific trade licenses directly from the Building Regulations Division"; "all other contractors are directed to the Business License Division to obtain their business license." A commercial builder files for the business license and sits no examination. Building Regulations (573) 634-6410, Business License Division (573) 634-6322.
Everywhere else. Other Missouri cities and counties write their own ordinances, and outside city limits many rural counties have no building permit program at all. Before bidding, ask each jurisdiction whether it licenses builders or only the trades, whether it will accept an ICC or Prometric score in place of its own test, and what business license, workers' compensation proof and insurance it requires. Expect to hold a separate credential in every jurisdiction where you pull permits.
