Washington Home Inspector License Requirements (2026)
By Gabriel Giner, Editor · Reviewed 2026-06-29 · CLR Editorial Review Desk
Washington licenses home inspectors at the state level through the Department of Licensing (DOL), which administers the Home Inspector Program under Chapter 18.280 RCW and the implementing rules in Chapter 308-408A WAC. The Home Inspector Advisory Licensing Board advises the DOL Director and approves curriculum and continuing education. To qualify, an applicant must complete a board-approved 120-hour Fundamentals of Home Inspection course, complete 40 hours of mentored field training that includes 5 actual inspections, and pass the PSI-administered examination covering a national portion and a Washington state-specific portion. The first license costs $720, runs on a two-year cycle that expires on the licensee's second birthday following issuance, and requires 24 clock hours of board-approved continuing education each renewal period.
The Licensing Authority

The Washington State Department of Licensing issues and regulates home inspector licenses through its Home Inspector Program. The Home Inspector Advisory Licensing Board advises the DOL Director and approves the required curriculum and continuing education courses.

Baseline Eligibility
Eligibility begins with two baseline checks: the applicant must be 0 or older and must provide a valid Social Security Number. No Washington residency is required. Inspectors licensed in another state who have been in good standing for at least 2 of the last 4 years, and whose prior education and training meet or exceed Washington's standards, may take only the Washington state portion of the examination in lieu of the full education and training path (WAC 308-408A-040).
Good moral character
Chapter 18.280 RCW and the DOL home inspector program pages consulted do not state an explicit good-moral-character standard; confirm current conduct and disciplinary provisions with the DOL before filing.
Background investigation
A background check requirement was not confirmed on the official DOL home inspector pages or in Chapter 18.280 RCW; the applicant should confirm any current screening step directly with the DOL before applying.
Experience and Education Requirements
Rather than a set number of years, the cited materials define eligibility through 120 hours of board-approved Fundamentals of Home Inspection education plus 40 hours of mentored field training with an experienced home inspector, including 5 actual inspections completed during the training period..
Accepted proof of experience or eligibility
- Certificate of completion for the Washington State Home Inspectors Board-approved 120-hour Fundamentals of Home Inspection course
- Documentation of 40 hours of mentored field training, including the 5 actual inspections completed during training
Education substitution
Out-of-state inspectors licensed and in good standing for at least 2 of the last 4 years, whose education and training meet or exceed Washington's standards, may take only the Washington state portion of the exam in place of the full education and field-training path (WAC 308-408A-040).
The Licensing Examination
There is no statewide written trade test for this credential in the cited record; the controlling process is: PSI Exams administers the Washington Home Inspector Examination, which includes a national portion and a Washington state-specific portion. New applicants take the full examination; qualifying out-of-state inspectors take only the Washington state portion. RCW 18.280 authorizes a psychometrically valid and reliable exam that the board may adopt from a national entity with a Washington-specific section included.
Examination fee: $300
Retake policy: Full re-examination is $300, the national-portion re-exam is $250, and the state-portion re-exam is $125. Applicable exam portions must be passed within a 2-year eligibility period before applying for the license.
Financial Security and Insurance
The relevant coverage for a home inspector is professional liability (E&O), not a contractor surety bond. The exact obligation in this state is set out below.
General liability
Errors & omissions (E&O) insurance is not required for licensure. Chapter 18.280 RCW and the DOL home inspector program do not mandate E&O coverage, though private associations or clients may require it independently of the state.
Workers' compensation
Not addressed in the verified record; an inspector who employs staff should confirm Washington workers' compensation obligations separately with the Department of Labor & Industries.
Additional financial requirements
Not required by Chapter 18.280 RCW or Chapter 308-408A WAC.

Persons licensed as home inspectors in another state may become licensed in Washington if that state's licensing requirements meet or exceed Washington's and the applicant passes the Washington portion of the examination (RCW 18.280). Out-of-state inspectors in good standing for at least 2 of the last 4 years may sit for only the state portion of the exam and must document that their education and training meet or exceed Washington's standards (WAC 308-408A-040).

The Licensing Roadmap
- Complete the board-approved 120-hour course. Enroll in and finish a Washington State Home Inspectors Board-approved 120-hour Fundamentals of Home Inspection course, and retain the certificate of completion.
- Complete 40 hours of mentored field training. Work 40 hours of mentored field training with an experienced home inspector, including 5 actual inspections completed during the training period, and document the experience.
- Register for and pass the PSI examination. Schedule the Washington Home Inspector Examination with PSI and pass both the national and Washington state portions; applicable portions must be passed within a 2-year eligibility window before applying.
- Pay fees and submit the license application to DOL. Submit the application to the Department of Licensing with the $720 first-license fee (which covers application and initial license) and the $300 exam fee; payment is accepted online or by mail, not by phone or in person.
- Receive and print the license. Once approved, print the license online for free or request a mailed copy for the $5 print fee, and begin operating under the Home Inspector License.
- Track the 2-year renewal cycle and continuing education. Complete 24 clock hours of board-approved continuing education each cycle and renew before the license expires on the licensee's second birthday following issuance to avoid late fees and reinstatement penalties.
Common Application Pitfalls
The following pitfalls summarize the issues most likely to delay, return, or derail a Washington Home Inspector application based on the published board instructions and source materials cited on this page.
Assuming the exam fee is the whole cost
The $720 first-license fee is separate from the $300 examination fee, and neither includes the private tuition for the required 120-hour course and 40 hours of mentored field training.
Letting the exam eligibility window lapse
Applicable exam portions must be passed within a 2-year eligibility period before applying; passing too early without applying can force a costly re-examination.
Missing the birthday-based renewal date
Licenses expire on the licensee's second birthday following issuance, not a fixed annual date; missing it triggers a $485 late renewal and a $150 reinstatement penalty.
Skipping board-approved continuing education
Only Program/board-approved continuing education counts toward the 24 clock hours required each cycle, so non-approved coursework will not satisfy the renewal requirement.
