South Dakota to Washington: residential contractor license reciprocity

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

South Dakota 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 South Dakota has nothing to transfer

South Dakota residential contractor

Licensed by cities and counties

Verified September 17, 2026· 11 sources

South Dakota issues no state residential contractor, home builder or remodeler license, and no state board examines or qualifies people who build houses. The Department of Labor and Regulation's list of occupational licensing agencies contains an Electrical Commission, a Plumbing Commission and a Board of Technical Professions for architects and engineers, and no contractor board of any kind, so a builder who self-performs electrical or plumbing work needs the matching state license and everything else is local. Cities decide who may build houses inside their limits, and the four largest programs are quite different from one another: Sioux Falls requires a Residential Building Contractor's license with its own written examination, a $20,000 compliance bond and $300,000 of liability insurance; Rapid City issues a Class B residential contractor license on a city examination; Aberdeen licenses residential contractors after an open-book examination and a City Council vote; Brookings issues an annual residential contractor license on insurance and a $75 fee with no examination at all. Separately from any of that, every contractor working anywhere in South Dakota must hold a contractor's excise tax license from the Department of Revenue before starting work, which is free and is a tax registration rather than a test of skill. A builder moving to South Dakota therefore has no state license to transfer and no state reciprocity to apply for: the work is registering for the excise tax license and then qualifying city by city, and only Aberdeen offers any credit for a license held elsewhere.

How local licensing works in South Dakota

How it works in South Dakota. There is no state contractor license, no state application and no state examination, so nothing carries automatically from one South Dakota city to the next, let alone from another state. What every contractor does need before starting work anywhere in the state is a contractor's excise tax license from the Department of Revenue: 'an individual must be licensed before starting work in South Dakota' and 'all contractors must be licensed regardless of the amount of the receipts they have or the amount of tax due.' There is no fee for it, the excise tax itself is 2% of a prime contractor's gross receipts, and three of the four cities below want to see a copy of the license card before they will issue a city license. Get that first, then take each city in turn.

Sioux Falls. Building Services 'requires a Residential Building Contractor's License of all contractors doing work on residential 1- & 2-family dwellings and townhomes within the city limits', and the examples it gives run from sheds, decks, shingles and sheetrock to basement finishing and new construction. The license is held through a named Construction Supervisor, who must first pass the Construction Supervisor Examination: a timed open-book test on the City of Sioux Falls Residential Code Handbook, offered monthly, 50 questions, 'You must get 80% or higher to pass the test, therefore a maximum of 10 of the 50 questions may be incorrect.' The examination fee is $75.00 and the handbook is $10.00. 'Upon application the Construction Supervisor must submit a $20,000 Compliance Bond, a minimum of $300,000 general liability insurance and the appropriate license fees within 90 days of examination.' Licenses run three years, one hour of continuing education is required in each cycle, and a license expired more than twelve months means sitting the examination again unless an inactive license was maintained. On out-of-state credentials the city is blunt: 'No, the city of Sioux Falls does not reciprocate any licenses. You will still need to take and pass examination before applying for the license.' The city does not print the license fee itself on the page, so ask licensing on 605-367-8672 what to send with the bond and the certificate. Sioux Falls also issues a separate Residential Roofing & Repair Contractor license and separate electrical, mechanical, plumbing, fireplace, refrigeration, irrigation, right-of-way and sign licenses.

Rapid City. Building Services licenses a Class B contractor 'for construction of detached single-family houses, attached single family houses and two-family dwellings', on a city-administered open-book examination based on the 2018 International Residential Code and the Rapid City amendments, 54 multiple choice questions in three hours, sat at City Hall. The license costs $200 initially and $100 to renew, runs three years and carries six hours of continuing education per period. Every applicant files a certificate of insurance naming the City of Rapid City as certificate holder and nothing else is accepted, with minimum general aggregate liability of $1,000,000, $300,000 fire damage and $1,000,000 each occurrence, plus a workers' compensation certificate or a signed statement of non-participation for an owner or partnership with no employees. A copy of the state excise tax certificate goes in the packet. Roofing is a separate Class R license, also $200 for three years, on a 12-question examination. A licensee who misses renewal has a one-year grace period, after which the license lapses and the examination must be taken again. Building Services is on (605) 394-4120.

Aberdeen. The city is explicit that location makes no difference to whether you need its license: 'Whether you are based in the City of Aberdeen itself, a different city within South Dakota, or you are based out of a completely different state all together, you must be licensed through the City of Aberdeen.' The examination is 50 questions, open book, two hours, with a passing score of 70%, studied from The Contractors Handbook at $15, and '$35 fee will be charged every time an exam is attempted or passed.' Aberdeen is the one place in the state that gives any weight to a license held elsewhere: 'the examination requirement may be waived if proof of prior licensing from recognized jurisdictions is approved by the City of Aberdeen's Building Official.' No jurisdiction is named on the handout, so bring the license and the licensing authority's own documentation and ask the Building Official first. After passing or being waived, the applicant files a $200 first-time fee covering three years, proof of liability insurance, proof of workers' compensation insurance if applicable, and a copy of the excise tax license, and is then approved by the City Council, which meets Monday evenings; paperwork is due by noon the previous Wednesday and permits may be drawn only after the vote. Renewal is $150 every three years. Building Inspection is at City Hall, 123 South Lincoln Street, 3rd Floor, 605-626-7017.

Brookings. Community Development issues a residential contractor license on paperwork alone. The requirements are the application, a $75 fee, an excise tax number, a copy of workers' compensation insurance and 'a copy of current General Commercial Liability Insurance Certificate stating the sum of not less than $500,000 for each occurrence.' There is no examination and no bond. The license year is the calendar year, January 1 to December 31, and it 'must be renewed in order to continue any current project or prior to starting any new project'; a contractor with a job in progress who lets it expire pays double the fee. The license is neither refundable nor transferable. Building permits are required in the city and on nonagricultural land in the joint jurisdictional area roughly three miles out. Community Development is at 520 3rd Street, Suite 140, (605) 692-6629.

Everywhere else. Smaller South Dakota cities set their own rules and many require only a permit and proof of insurance. Ask the building official in each city you intend to work in, and remember that the excise tax license is required statewide whether or not the city licenses anybody.
