Becoming a home inspector in Washington is an exciting step toward building your own business, and earning your license involves a few key milestones, from completing approved coursework and field training to passing the Washington Home Inspector Exam. WIN Home Inspection helps you complete your licensing requirements while providing the guidance and support you need to get your inspection business started. Below are the key requirements to get your Washington home inspector license:
Yes, a license is required to perform home inspections in Washington.
120 Hours of board-approved classroom instruction (“Fundamentals of Home Inspection”).
40 Hours of supervised field training (including at least 5 actual home inspections).
Washington Home Inspector Examination (includes National and WA State portions).

24 hours every 2 years.
License must be renewed every 2 years on the applicant’s birthday.
Becoming a home inspector in Washington starts with learning and taking an exam. Thereafter, you can apply for a license and start your career. We can break the process into five steps:
You’ll start by completing a “Fundamentals of Home Inspection” 120-hour course, which must be approved by the Department of Labor (DOL). Here, prospective inspectors learn the core components of a home, including structural systems, roofing, plumbing, electrical systems, HVAC, insulation, and the Washington Standards of Practice. According to state laws, you must complete the course in a classroom setting.
Having covered the theory, the next step is to apply your newfound knowledge in the field. You’ll spend 40 hours in inspection sites under a licensed Washington home inspector who will act as your supervisor. During this time, you need to complete at least 5 home inspections and write comprehensive reports. Your supervising mentor will read and certify them.
Once you’re through class and field work, the next step is taking the Washington Home Inspector Examination administered by PSI. It includes a $300 exam fee, and all applicants must pass the exam before proceeding to the next steps. You’ll be tested on national home inspection knowledge and Washington State-specific statutes.
You’ve been to the classroom and the field, and you’ve passed the home inspector exam. Now it’s time to get your license. Create an account on the state’s SecureAccess Washington (SAW) portal to submit your official Home Inspector License Application. The requirements you need to upload are:

You’ll also have access to proprietary reporting software and in-house training for 35+ specialized services to set you up for success from day one.
While classwork and field training teach you the fundamentals, learning the Pacific Northwest climate conditions and local construction types will set you apart. Important considerations for Washington inspectors include:
The Pacific Northwest region is usually damp. So, many prospective home buyers prioritize evaluating roof drainage, gutter systems, exterior flashing, site grading, and bulk water management.
In Washington, soil moisture levels are usually high. It’s the inspector’s responsibility to point out standing water, inadequate vapor barriers, poor ventilation, and organic growth in crawlspaces.
There are numerous pine and fir tree shades in the Evergreen state, which accelerate moss and algae growth on roofing materials. Experienced home inspectors know to look for premature shingle degradation and rot.
It’s not unusual to find century-old Craftsman homes in Seattle and Tacoma and coastal properties along the Puget Sound. As an inspector, you must evaluate legacy electrical setups, older plumbing lines, and saltwater air wear.
Getting licensed is just the first step. WIN backs you up with a proven brand, a national footprint, and decades of real operating experience, so you can focus your energy on growing the business, not figuring it out alone.
