Spokane, Washington, is a mid-sized city with a growing population of approximately 230,000 residents and a metropolitan area exceeding 550,000. The local economy is diverse, including healthcare, education, manufacturing, and a rising tech sector. The window cleaning market in Spokane benefits from distinct seasonal patterns: wet, snowy winters and dry, dusty summers. Spring and fall are peak seasons as homeowners and businesses prepare for weather changes. The market is moderately competitive, with a mix of national franchise operators and independent local cleaners. Residential demand comes from single-family homes, especially in neighborhoods like South Hill, the South Perry District, and the Five Mile area. Commercial demand is strong in downtown Spokane, the Spokane Valley, and along the Division Street corridor. New construction in the Kendall Yards and Barker Road areas also creates recurring contract opportunities. The average price point is slightly higher than rural areas due to the higher cost of living, but customers value reliability, safety, and eco-friendly practices. The market has room for a well-branded, locally focused newcomer who can leverage digital presence and community trust.
In Washington State, any individual or company performing window cleaning services must first register with the Washington Department of Revenue (DOR) to obtain a Unified Business Identifier (UBI) number. This is the primary state-level business license. You must also register for a Business License from the City of Spokane. The City requires a General Business License, which can be obtained online through the Spokane Business License Center. Fees are modest (typically $50–$100 annually). If you plan to use any cleaning chemicals that contain regulated substances, you may need additional permits from the Spokane Regional Clean Air Agency, though most residential window cleaners use simple soap and water.
While not legally mandated for all window cleaners, getting general liability insurance is strongly recommended and often required by commercial clients and homeowner associations. Washington does not have a state-level bonding requirement specifically for window cleaning, but many Spokane property managers will insist on $1 million in liability coverage. You may also want a surety bond to protect against damages. Worker's compensation insurance is mandatory if you hire employees; the Washington State Department of Labor & Industries oversees this. For a sole proprietorship, you can opt out of worker's comp for yourself, but you must file a statement.
If you use ladders, scaffolding, or any equipment that extends above 10 feet, you must comply with Washington's safety regulations. You may need to register as a "commercial window cleaner" if working on commercial buildings over three stories. The Department of Labor & Industries offers free safety consultations. Also, if you perform work on buildings with lead-based paint (common in older Spokane homes built before 1978), you may need EPA Renovation, Repair, and Painting (RRP) certification, though window cleaning alone is often exempt. Check with the Spokane Regional Health District for specific guidance.
Washington has no state income tax, but you must collect and remit sales tax on your window cleaning services. The state sales tax rate is 6.5%, with Spokane County adding an additional 1.6% (total 8.1% as of 2025). You must file periodic excise tax returns with the DOR. Keep meticulous records of all transactions.
Visit google.com/business and sign in with a dedicated Gmail account. Enter your business name exactly as you want it to appear (e.g., "Spokane Shine Window Cleaning"). Verify your location by postcard (Google will mail a code to your Spokane address). You may also be eligible for phone or video verification if you have an existing verified phone number with Google. Do not use a PO Box as your service area address unless you also provide a physical location open to customers. For a mobile window cleaning business, you can hide your street address and set a service area covering Spokane and surrounding zip codes (e.g., 99201, 99202, 99203, 99204, 99205, 99206, 99207, 99208, 99212, 99223, 99224, 99026).
