Washington has always been a place of great beauty, new beginnings, and a frontier lifestyle. It makes sense that Washington is a great place for tiny houses. With some of the most impressive landscapes in the world, Washington has it all—mountains, desert, beaches, and more. Year-round warm weather makes it an excellent climate for an outdoor-friendly, active lifestyle. Washington is perfect for homesteading, living on the road, or setting up a foundation and building a tiny house. Some of the best areas for living the tiny house lifestyle are Seattle, Olympia, and Spokane.
Seattle, WA
For tiny house dwellers, life in the Emerald City (also known as Seattle) offers affordable living in an expensive area. Seattle’s plumb location attracts nature lovers for its spectacular landscape, but the thriving job market, especially in the tech arena, is also a big draw. Seattle residents are notoriously laid back and invested in sustainability and eco-friendly initiatives—the perfect environment for tiny house enthusiasts.
Olympia, WA
Olympia may be the smallest capitol city in the United States, but it has got a lot going on, is tiny house friendly, and is a lot less expensive than some of the other Washington metro areas. Neighborhoods range from quiet residential areas in northeast Olympia to hip, trendy (and more expensive) Johnson Pointe near Puget Sound.
Spokane, WA
Another tiny house welcoming location, Spokane’s motto is “Near Nature, Near Perfect,” and it really lives up to the ideal. Within easy driving distance of mountains and forests, and a river running right through the middle of the city, Spokane is heaven for anyone who loves nature. Five colleges and an active cultural scene make for a city that’s fun and interesting with a high walkability score.
Washington tiny house communities are steadily growing in number. New places are cropping up that allow people to park their THOWs or build on a designated spot with access to community amenities like sewer, water, and even gardening. Here are a few of the best Washington tiny house communities to explore.
Lost Lake Resort
Lost Lake Resort’s Nisqually Valley location may feel like a remote forest on the shores of a lake, far from civilization, but in reality, you’re just 50 miles from Seattle. It’s the perfect tiny home retreat for lake-front living. Swimming, boating, fishing, canoeing, and other outdoor activities are popular among residents, along with hiking and biking. Amenities include playgrounds, an exercise room, mini-golf, an indoor/outdoor pool and hot tub, and more. To live there, you purchase a lot and bring your park model or tiny house on wheels (THOWs). Annual park dues of $2,760 pay for maintenance and amenities.
Quixote Communities
Quixote Communities is on a mission to provide safe, stable housing for veterans in Orting, Olympia, and Shelton. This faith-based tiny house community is eco-friendly and offers 144 square feet tiny houses arranged around a common green area and a large community center where residents can gather, share weekly dinners, and take yoga and life skills classes.
Recently, Washington adopted new laws to make tiny house living easier and more accessible. The new laws allow local municipalities to approve multi-unit lots for tiny home communities, eliminates any single-family dwelling minimum square foot requirements, adds tiny houses and THOWs to the definition of factory-built housing so they can be included in RV and trailer parks, and clears a regulatory pathway to allow Eco-villages and tiny home communities.
Effective from Feb 2021, the State of Washington adopted Appendix Q – Tiny houses, with amendments.
Appendix Q provides standards and regulations for tiny homes with a foundation of 400 square feet or less and was adopted into the 2018 International Residential Code (IRC) building code. The appendix relaxes certain code requirements for stairs leading to a loft area, reduced ceiling heights in lofts, and air leakage testing.
Here’s how Washington defines tiny houses:
Permanent Tiny Houses in Washington
There is still no official maximum size for a tiny home on permanent foundations in Washington, but they are typically less than 600 square feet in size.
If you’re building a tiny house on the site where you intend it to be occupied and used, contact your local building department. Remember to ask about electrical inspections as well as any other inspections and paperwork needed along the way.
If you’re buying a manufactured home of any size, including a tiny home, contact your local building department to find out where your home can be located. L&I oversees regulation for the construction of tiny houses that are built anywhere other than where they are intended to be used. Whether it’s constructed in a factory, a workshop, or a backyard, if you plan to use it somewhere else, you’ll need to contact L&I to arrange plan reviews, inspections, and permits.
Tiny Houses on Wheels in Washington
A tiny house on wheels (THOW) is defined as “a dwelling that may be built on wheels and is no larger than 400 square feet, including a kitchen, bathroom, and sleeping/living area, and must be built to the Washington State Building Code.” Any tiny house on wheels in Washington State must have full inspections and approvals from the Department of Labor and Industries. This includes tiny homes purchased from out-of-state manufacturers. The approval process for THOWs depends on where it is built, so get in touch with L&I to be sure you’re following the regulations for your particular tiny house.
If you’re building a structure with wheels that don’t meet the tiny house definition above, you might be building a park model or recreational vehicle. These units are inspected and regulated by Labor and Industries. Contact your local building department to discover where you’re allowed to locate your structure.
Laws may vary by county, city, or town. While the laws may relax the state regulations, they may not impose additional restrictions. Here are the regulations in key counties in Washington:
