Oklahoma to Washington: residential contractor license reciprocity
Oklahoma 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 Oklahoma has nothing to transfer
Oklahoma residential contractor · “Residential building contractor license or registration (city-issued)”
Licensed by cities and counties
Issued by No state authority for building contractors; cities register residential builders
Oklahoma issues no statewide residential building, home builder or home improvement contractor license, and the Construction Industries Board says so on its own home page: "General Contractors are not currently required to have a state license in Oklahoma for general contracting. However, trade licenses/registrations are required for performing, or offering to perform, licensed/registered trade work. Further, local jurisdictions should be contacted for any local requirements." What the CIB does regulate is plumbing, electrical, mechanical, roofing, building and construction inspectors, and home inspectors. One of those is genuinely statewide for a residential contractor: roofing. Under the Roofing Contractor Registration Act, resident and non-resident roofing contractors alike must hold a CIB roofing contractor registration before they engage in or offer roofing services anywhere in Oklahoma, which costs $75, runs through a named qualifying party and needs at least $500,000 of liability insurance; failing to register is a misdemeanor. Everything else about housing is local. Oklahoma City registers a Building Contractor (Residential Only) for $100 on insurance alone, Edmond issues a separate residential building contractor license conditioned on current general liability and workers' compensation, and Broken Arrow registers general contractors on a $50,000 liability certificate. Tulsa and Norman license only the trades and leave the homebuilder to pull permits without a city contractor credential. None of these involves an exam, a bond, experience or a financial statement, and none of them gives credit for a license held in another state, so an inbound residential builder registers in each city where permits will be pulled, registers with the CIB if roofing is in scope, and makes sure any plumbing, electrical or mechanical work is performed under the right CIB license.
How local licensing works in Oklahoma
How local licensing works. Oklahoma has no state homebuilder or remodeler license, no state qualifying party for building work and no state reciprocity for it. Statewide residential and commercial building codes are adopted by the Oklahoma Uniform Building Code Commission and enforced by local building departments, so the contractor rules come from each city. Identify the city or county with jurisdiction over the address, register there, and expect to repeat the filing in the next jurisdiction. Two state obligations follow the contractor everywhere: a CIB roofing contractor registration for any roofing work, and a CIB plumbing, electrical or mechanical license for any of that work that is self-performed.
Roofing is the statewide exception. The Roofing Contractor Registration Act "creates a procedure whereby resident and nonresident roofing contractors are required to obtain a valid registration from the CIB in order to engage in or offer to engage in roofing-related services in the State of Oklahoma", and "failure to register is a misdemeanor punishable by a fine of up to $500.00." Registration is $75 initially and $75 to renew each year, and requires a general liability certificate of at least $500,000 naming the Construction Industries Board as certificate holder and specifically covering roofing work, proof of workers' compensation coverage or exemption, the business name registered with the Oklahoma Secretary of State, entity formation documents, and an affidavit of lawful presence. A qualifying party must be at least 18, must be an owner, officer, member or general partner, and must be "actively engaged in the work undertaken by the registrant." Registrations are non-transferable. A residential-only roofer stops there: "roofing contractors who do not perform commercial roofing contractor work and only perform residential roofing contractor work do not need to obtain a commercial endorsement."
Oklahoma City. Development Services registers contractors under Chapter 12 of the Municipal Code. The residential category is Building Contractor (Residential Only), defined as "any person contracting to make or provide any beneficial or valuable change or addition, betterment, enhancement, or amelioration of upon or to any new, proposed or existing structure on private property for which a building permit is required." The filing is a general liability certificate of at least $50,000 per occurrence, workers' compensation of at least $100,000 per occurrence or an Oklahoma Workers' Compensation Commission Affidavit of Exempt Status, an immigration affidavit where applicable, and a $100 registration fee. There is no bond, exam or experience requirement. Electrical, mechanical and plumbing contractors register separately and must show a current CIB state license first; boiler contractors must hold Oklahoma Department of Labor licensure. Development Services, 420 W. Main St., (405) 297-2525.
Tulsa. The Development Services Permit Center "permits all development within the city and registers the licenses of trade contractors", and the city's own guide states that "the State of Oklahoma licenses trade contractors (electrical, fire, mechanical, and plumbing) who must then register with the City of Tulsa." Registration is done on an Account Information and Contractor Registration form whose trade list includes Building, Mechanical, Plumbing, Electrical, commercial fire sprinkler, fire alarm, house moving, demolition, fire extinguisher and suppression systems, and sidewalk, driveway and paving cut work; the state control number field is marked "if applicable", and the account carries an undertaking to provide general liability insurance naming the City of Tulsa as an additional insured with 30 days' notice of cancellation. There is no exam, bond, experience or financial requirement on the form, and the city no longer registers journeymen, apprentices or sign and electrical sign contractors. Permits that require a contractor license must be applied for through the contractor's own portal login. A Residential Fast-Track Program gives one-business-day issuance of residential interior remodel permits for $500 plus the permit fees, by appointment. Permit Center, 175 E. 2nd Street, 4th Floor, (918) 596-9456.
Norman. The city licenses three things and a homebuilder is not one of them. Trade Contractor licenses for electrical, mechanical and plumbing require a current active CIB state license in hand and shown active on the CIB site, plus a driver's license or state ID; they renew annually on notices mailed in mid-February with a 31 March due date. A Sign Contractor license requires a $2,000 corporate surety bond or certificate of deposit on the city's own bond form, renewed annually. A Structure Moving license requires a casualty insurance certificate of at least $100,000 and proof of unified carrier registration or an intrastate license. A residential builder in Norman applies for permits through the online portal and carries no separate city contractor license. Development Services, (405) 366-5339.
Broken Arrow. The Community Permitting and Licensing Division handles residential and commercial building permits, sign permits, zoning cases and contractor registration through the Citizen Self Service portal. The city's General Contractor Registration form asks for four things and nothing else: a current general liability insurance certificate showing the business name and address, naming the City of Broken Arrow as certificate holder, with minimum $50,000 coverage; a current workers' compensation certificate or an Affidavit of Exemption; the City of Broken Arrow named as certificate holder on every certificate of insurance; and a copy of the contractor's driver's license. There is no exam, bond, experience requirement or state license prerequisite, and the form prints no fee, so confirm the current amount before filing. Community Development, P.O. Box 610, Broken Arrow, OK 74013, 918.259-8333, [email protected].
Edmond. Building & Fire Code Services is the one Oklahoma jurisdiction on this page that separates the two tiers explicitly. "Residential building contractors must maintain current general liability and workman's compensation for permit submittal", and a new residential building contractor license is opened by emailing the office the company name, mailing address, contact phone number, current general liability insurance, current workers' compensation and the portal email. A general building contractor license is a separate credential. Trade contractors "are required to hold active city and state licenses" and file their current CIB license and driver's license. Trade licenses expire on 31 July each year, renew from July through August through the portal, and lapse on 1 September if unpaid. No exam, bond or experience requirement is published for either building license. 22 E. Main Street, Edmond, (405) 359-4780.
Everywhere else. Smaller Oklahoma cities and rural counties vary from a full registration program to nothing beyond a building permit. Where a jurisdiction has not adopted a state-recognized code, does not require permits and employs no inspector, a contractor installing, modifying or altering plumbing, electrical or mechanical systems must file a Notification of Work Without Permit with the CIB instead.
