Illinois to Washington: residential contractor license reciprocity

No credit· Start overVerified September 17, 2026· 15 sources

Illinois 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

  1. 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..
  2. 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..
  3. 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..
  4. 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..
  5. 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..
  6. 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..
  7. 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..
  8. 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.

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 Illinois has nothing to transfer

Illinois residential contractor · “No statewide license; local titles include Chicago General Contractor Class D or E and Chicago Home Repair

Licensed by cities and counties

Verified September 17, 2026· 19 sources

Illinois issues no statewide residential contractor, home builder or remodeler license, and no state agency examines or qualifies people who build or remodel houses. What the State does license is narrower and worth knowing: the Department of Financial and Professional Regulation licenses roofing contractors under the Illinois Roofing Industry Licensing Act, where a limited license covers residential properties of eight units or less and an unlimited license covers residential, commercial and industrial roofs, and a municipality or county may not issue a building permit to a roofing contractor without proof of that state license. IDFPR also licenses architects, professional and structural engineers, land surveyors and alarm contractors, and the Department of Public Health licenses plumbers, plumbing contractors and irrigation contractors, but nowhere on IDFPR's list of regulated professions is there a general, residential or building contractor. Everything else is local: Illinois municipalities are home rule units and license or register residential contractors one jurisdiction at a time, with the City of Chicago's General Contractor license by far the most consequential. A builder moving to Illinois therefore has no state license to transfer and no reciprocity to apply for; the practical work is registering in each city or county where they will pull permits, carrying the insurance each one demands, and obtaining the state roofing license if the company will do roofing. Statewide consumer law still applies: the Home Repair and Remodeling Act requires a written contract for any home repair or remodeling job over $1,000 and the "Home Repair: Know Your Consumer Rights" pamphlet on every job.

How local licensing works in Illinois

How it works in Illinois. There is no state license, no state application and no state exam for residential contractors. Each municipality decides who may pull a residential building permit, so a contractor must be licensed or registered separately in every jurisdiction where they build, and a credential from one Illinois city is not valid in the next. Almost all of these local programs are about identity, insurance, bonding and fees rather than trade competence, and none of them reviews or credits a residential contractor license held in another state. Roofing is the exception in the other direction: the State license is mandatory everywhere in Illinois, and cities from Rockford to Joliet to Cook County check it at the permit counter.

Chicago. This is the license that matters. 'A City of Chicago general contractor license is required to perform most types of building construction, alteration, repair, and demolition work within the City of Chicago', and it is needed to bid on, undertake, hire or supervise, or control the means and methods of work requiring a building, sign or demolition permit. Licenses are issued to businesses, including sole proprietorships, in five classes set by project value - the fair market value of materials and labor supplied by all contractors and subcontractors across all concurrent and consecutive work at the same site. The two classes a homebuilder or remodeler usually needs are Class D, capped at $4 million with ordinary demolition and $2 million per occurrence of insurance, at a $900.00 license and renewal fee, and Class E, capped at $500,000 with no demolition and $1 million per occurrence, at $300.00. There is no exam, no experience review and no qualifying party. The application asks for a statement of financial solvency in the format supplied, proof of authority to do business in Illinois (not required for sole proprietors), an Assumed Name Certificate from the County Clerk if a trade name is used, proof of insurance for the class from an insurer authorized in Illinois and rated B+ or better by A.M. Best, and government photo identification for the controlling persons. Continental Testing Services processes the application and renewal by mail for the Department of Buildings; the license runs one year and 'is automatically inactivated if the associated insurance policy expires.' Reinstatement costs $100.00 per year or part year expired.

Chicago, work that does not need a permit. A business that fixes, replaces, alters, modernizes, improves or adds to residential property but does not need a building permit takes a Home Repair license from Business Affairs and Consumer Protection instead: $1,000.00 for a two-year term, with a certificate of insurance of at least $300,000 per occurrence, and the rule that 'Home Repair licensees may not pull building permits.' A general contractor license replaces it - 'a home repair license is not required for a business that holds a General Contractor license', though a general contractor doing residential work must still follow the home repair consumer protection rules, which include a written estimate before work, a written invoice on completion, prior approval before exceeding the estimate, and the license number on contracts, advertisements and vehicles. Acquiring vacant land to build a new home, or renovating more than half of an existing building's floor area, requires a separate Residential Real Estate Developer license.

Cook County (unincorporated areas). 'All contractors performing work in unincorporated Cook County are required to register with the Cook County Department of Building and Zoning.' Registration costs $150 per trade initially and $75 per trade annually, due by December 31, and needs a $1,000,000 general liability certificate naming Cook County Building and Zoning at 69 W. Washington, Suite 2830, Chicago as certificate holder, filed by the owner or a corporate officer with the Articles of Incorporation or the current Annual Domestic Report. Roofing registrants must submit the State of Illinois roofing license and demolition registrants an approved bond. There is no exam. Homeowners who live on the property get 'General' contractor registration free of charge. Use the county's CookViewer tool first to check whether a site is actually unincorporated. Contact [email protected] or 312-603-0512.

Aurora. The Division of Building and Permits registers a General contractor for a $200 fee. The packet is the Contractor Licensing Application, a certificate of insurance naming the City of Aurora as primary and non-contributory additional insured with $1,000,000 general aggregate and $500,000 per occurrence, workers' compensation in compliance with Illinois statute, and proof the business is registered with the Secretary of State or a county DBA certificate. There is no test for the General category - Aurora's municipal testing applies only to electrical and mechanical contractors, who may use ICC certifications or a license from an accepted testing municipality instead. Roofing registration is also $200 and requires the state license, and workers' compensation cannot be replaced by an employee affidavit for roofers. Outstanding or expired permits will block a renewal. Submit to [email protected]; 77 S Broadway, (630) 256-3130.

Evanston. 'All contractors performing work within City limits are required to register with the City, including but not limited to General Contractors, Electrical, Carpentry, Concrete, Excavation, Masonry, Landscaping, Fence, Roofing and Sign contractors.' General Contractor registration is $150 and trade registration $125, both renewable annually through the Citizen Portal. Insurance must be general liability of at least $300,000 per occurrence, bodily injury of at least $100,000 per occurrence, property damage of at least $100,000 per occurrence and workers' compensation at statutory minimums, with Evanston as certificate holder; sole proprietors and partnerships with no employees may file an affidavit in place of workers' compensation, and right-of-way work needs $1,000,000 per occurrence naming the city as additional insured. State-regulated contractors submit a copy of the state license. An owner-occupant of a single-unit residence may act as their own general contractor.

Joliet. 'All contractors performing work within the City of Joliet must have current registration on file prior to permit issuance. There are no forms or fees for registration, unless you are a Sign Erector or for HVAC Testing.' Registration is a certificate of insurance naming the City of Joliet as certificate holder, with minimum limits of $250,000 bodily injury per person, $500,000 bodily injury per occurrence and $250,000 property damage per occurrence, emailed to [email protected]. Roofing needs the Illinois State Roofer's License, plumbing the Illinois Plumbing Contractor Registration, irrigation the state irrigation license, siding a Vinyl Siding Installers certificate, and electrical and HVAC a license from one of the municipalities Joliet accepts. Electrical, plumbing and HVAC contractors also file a project-specific Letter of Intent, and all subcontractors must be listed on the permit application.

Rockford. 'General contractors are not required to be licensed.' Rockford requires a building permit for any structure over 120 square feet that is constructed, altered, enlarged, repaired or moved, and for all roofing work, and notes that 'roofing contractors are required to obtain a license from the State of Illinois Department of Professional Regulation.' Tent erectors and outdoor sign contractors need annual city licenses.

Springfield. The Building and Zoning Department's published list of applications contains electrical and mechanical contractor registrations and licenses and nothing else for contractors - there is no general contractor or home improvement registration. The city's building permit application collects the general contractor's name and address but asks for a license number only on the roofing line. Building and Zoning is at 300 South 7th Street, Room 304, (217) 789-2171.

Peoria. Peoria's Contractor Business Licenses cover only four activities - parking lot paving, sidewalk and driveway work, placing a dumpster or storage unit in the right-of-way, and sewer connections - at $25.00 or $60.00 a year with license and permit bonds of $5,000 or $10,000. Its trade licenses cover electrical and HVAC contractors at $150.00 each, issued to individuals rather than businesses and requiring an open-book ICC exam unless the applicant holds a Normal or Pekin license, plus boiler tender and stationary engineer licenses. There is no general building contractor or residential builder license in Peoria.

Everywhere else. Other Illinois municipalities set their own rules and most of them register rather than license residential builders. Ask the building or development services department of each city, village or county before contracting there, and confirm the current fee and insurance limits before buying coverage, because these are set locally and change independently.
