Washington has no reciprocity agreement with Oklahoma. A Oklahoma home inspector applies by endorsement.

Out-of-state licensee: Washington state portion of the examination only (every state)

The board reviews your out-of-state credentials case by case. Some exam is usually still required, often only a law or code exam.

Washington publishes one rule for inbound inspectors and applies it the same way whichever state you come from. RCW 18.280.180 lets a home inspector licensed in another state become licensed here provided that state's licensing requirements meet or exceed chapter 18.280 RCW and you pass the Washington portion of the examination. WAC 308-408A-040 puts numbers on it: you must have been licensed and actively practicing as a home inspector for two of the last four years in such a jurisdiction, with your license in good standing, and you are then eligible to sit the Washington state portion alone. That is a real saving — the 175-question national portion is waived, and with it the 120 classroom hours of Fundamentals of Home Inspection and the 40 hours of supervised field training, provided you document education and training that meets or exceeds Washington's. Everything else stands: an officer of your origin board completes a license verification form, you pay the examination fee and the $720 first-license fee, and you renew every two years on 24 hours of Washington-approved continuing education.

RCW 18.280.180 is headed "Reciprocity", but the section names no partner state, rests on no signed agreement and does not waive any examination, so treat it as a case-by-case comparison of your origin state's requirements against Washington's rather than as a reciprocal arrangement. The Department publishes no list of the states it considers to meet or exceed chapter 18.280 RCW; it makes that judgment on your application, and the program office on 360-664-6487 is the place to ask before you file. There is no separate out-of-state application form — you file the ordinary Home Inspector Examination Application with the license verification form attached. On the national portion: Washington's own national portion is the National Home Inspector Examination, so an inspector who sat that exam elsewhere is looking at the same paper, but the rule waives it on the strength of your out-of-state license rather than on a previous score, and the Department publishes no provision for transferring an NHIE result from another state's sitting. An applicant who does not meet the two-in-four-years test takes the full examination and must complete the 120-hour course, which Washington insists be taken in a classroom rather than online. Military training or experience is accepted under RCW 18.280.200 unless the director finds it not substantially equivalent.

What you must already have

  • Your origin jurisdiction must have licensing requirements that meet or exceed those in chapter 18.280 RCW. This is the whole of the test — Washington names no partner states and holds no reciprocal agreements — and the Department applies it to your file when it reviews your examination application.Chapter 18.280 RCW sets the bar being compared against: 120 hours of board-approved classroom instruction, up to 40 hours of supervised field training, a psychometrically valid written examination, a two-year license term and 24 hours of continuing education every two years. The Department has not published which jurisdictions clear it, so ask the program before paying any fee. Washington's own summary of the requirement is "Documentation of education and training that meets or exceeds Washington's requirements", and the Department says you will be required to provide proof that you completed your training.
  • You must have held your Oklahoma license for at least 2 years.The Department's own tables put it as "licensed as a home inspector in good standing for at least 2 of the last 4 years". Someone who has been licensed for less than that, or who has been licensed but not practicing, takes the full examination and the full education and field training instead.
  • Your Oklahoma license must be active and in good standing.WAC 308-408A-040(2) requires the verification to come from the origin authority rather than from the applicant. Washington provides no separate reciprocity application form: the ordinary Home Inspector Examination Application is used, with the verification attached.
  • You must have no disciplinary action or unresolved complaints on your record.Washington also runs a criminal conviction screening service for professional license applicants, and a Professional License Criminal Conviction Screening Request form can be filed in advance to find out whether a conviction would disqualify you before you spend anything on education or examination fees.

What you'll do to get licensed in Washington

  1. 1Law / code exam. Pass a law, rules, or code exam. The Washington state portion of the home inspector examination — 24 questions in one hour, testing Washington laws and rules for home inspector licensing, with a scaled score of 70 required to pass. This is the part RCW 18.280.180 never waives: every inbound licensee sits it. The examination is delivered by PSI, at a test center or under remote proctoring, once the Department has verified your eligibility and issued an approval letter. A passing score is valid for one year, and the license must be obtained within that year or the examination is taken again. You may retake it after 24 hours' notice to the vendor and a 30-day wait, with no limit on attempts..
  2. 2Trade exam. Pass the destination's trade exam (if applicable). The national portion — 175 questions in three hours, on general home inspection practice, scaled score of 70 to pass. Washington's national portion is the National Home Inspector Examination, produced by the Examination Board of Professional Home Inspectors, which RCW 18.280.080 contemplates when it lets the board adopt an exam prepared by a national entity and requires a Washington-specific section to be added to it. It is marked optional here because the out-of-state route under WAC 308-408A-040 removes it: a qualifying inbound licensee sits the state portion alone. Anyone who does not meet the two-in-four-years test takes both portions. Note that the waiver runs off your out-of-state license rather than off a previous NHIE score, and the Department publishes no way to transfer a result from another state's sitting..
  3. 3Exam fee. Pay the exam fee ($125). Examination fee, paid to the testing vendor when you schedule. Washington's published schedule is $125 for the state portion only, $250 for the national portion only and $300 for both, so an inbound licensee approved to sit the state portion alone pays $125 where a new applicant pays $300. Re-examination is charged at the same rates. The fee is not refundable or transferable, and it is forfeited if you do not test within one year of the vendor receiving it. Payment is by card, e-check, cashier's check, certified check, money order or voucher..
  4. 4License fee. Pay the license or certificate fee ($720). First home inspector license, set by WAC 308-408A-090 and covering both the application and the initial license. It is paid after you pass, with a copy of your pass report, either online through a SecureAccess Washington account or by check or money order to the Department. Printing a copy of the license from your own account is free; a mailed copy costs $5..
  5. 5License fee. Pay the license or certificate fee ($415). License renewal, due every two years. The license expires on your second birthday following issuance, so the first term is often shorter than two full years and only the second is a full cycle. The Department mails a renewal notice about 60 days ahead. Late renewal costs $485 in total, which is the $415 renewal plus a $70 penalty. A license not renewed within one year of expiration is canceled, and reinstatement within two years of cancellation costs a further $150 penalty on top of the back fees, plus 24 hours of coursework completed in the preceding year including at least three hours on Washington home inspector law..
  6. 6Continuing education. Complete continuing education. 24 clock hours of instruction in courses approved by the Home Inspector Advisory Licensing Board, every two years, as a condition of renewal. The hours must be commenced within the 24 months before your renewal date and cannot be commenced before your first license is issued. Washington is strict about the source: unused hours do not carry over into the next period, continuing education from another profession does not count, and continuing education taken in another state does not count unless the course itself was approved by the Washington program. Approved courses may be repeated in later renewal periods, but instructors earn no credit for teaching or developing a course. Renewal carries an attestation, and a false attestation is a disciplinary matter..
  7. 7Other. The education and training an inbound licensee does not repeat: an approved Fundamentals of Home Inspection course of at least 120 clock hours, which Washington requires be taken in a classroom rather than online, plus 40 hours of field training on actual inspection sites supervised by a licensed inspector with at least four years of licensure, including at least five complete home inspections with a written report for each, reviewed and certified by the supervisor as compliant with the standards of practice. Travel, meals and report-writing time do not count toward the 40 hours. Both must be completed within the two years before the examination application. WAC 308-408A-050 also lets the director substitute equivalent higher-education coursework, with 60 hours of fundamentals plus a supplemental course able to meet the 120. (if applicable).
  8. 8Insurance. Carry the required insurance (if applicable). Washington requires none. The Department answers the question directly: there is no requirement to obtain insurance or to be bonded to be a home inspector, and neither chapter 18.280 RCW nor chapter 308-408A WAC imposes errors and omissions cover, general liability cover, a surety bond or any financial responsibility test. Cover is a commercial decision here rather than a licensing condition, which is unusual for this trade and worth weighing against what RCW 18.280.120 already puts on you: you and your company may do no work other than inspection-related consultation on a house you inspected for one year from the date of the report..

Issued by Washington State Department of Licensing, Home Inspector Program

Washington licenses home inspectors statewide. The Department of Licensing issues the license and runs the program on the advice of the Home Inspector Advisory Licensing Board, and since 1 September 2009 nobody may act as, advertise as or hold themselves out as a home inspector in Washington without one. The Department puts it plainly: the license is needed by anyone who examines the condition of a home for a fee. It is worth being clear about how much more this is than Washington asks of the people who build the houses — construction contractors merely register with the Department of Labor and Industries under chapter 18.27 RCW, on an application that asks for a business identifier, workers' compensation coverage and the names of the principals but sets no examination and no coursework at all — while a home inspector must complete 120 classroom hours, do 40 hours of supervised field training and pass a two-part written examination. There is a single license grade with no apprentice, associate or trainee tier below it. Washington requires no insurance and no bond of a home inspector, but the law does bar the inspector, and anyone at the same company, from doing any work other than inspection-related consultation on a house for a year after the report. Licenses run two years and expire on the licensee's second birthday following issuance.
