Are Tiny Houses Legal in Washington? A Clear and Confident Answer
Tiny houses have been gaining popularity in recent years due to their affordability and minimalistic lifestyle. However, many people are left wondering whether tiny houses are legal in Washington State. The answer is not a straightforward yes or no, as there are regulations and codes that must be followed.
Washington State has adopted Appendix Q Tiny Houses, which relates to tiny homes on a foundation. Tiny House Bill 5383, which became effective on July 28th, 2019, mandates that the building code council write building codes for tiny homes. Additionally, the state prohibits cities or towns from preventing the use of movable tiny homes as primary residences in manufactured or mobile home communities. However, local jurisdictions set their own codes and regulations, which may vary from town to town.
It is important to note that tiny houses with a foundation are more likely to be legal in Washington State than tiny houses on wheels. A tiny house with a foundation is a dwelling that may be built on a foundation 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. On the other hand, a tiny house on wheels must meet the State Building Code requirements and is considered a licensed legal vehicle, meaning it cannot be over 8′-6″ wide or 14′ in height when in travel mode.

Tiny houses that meet these codes are considered legal dwellings in Washington State.

While the Washington State Building Code provides the overarching legal framework for tiny houses, local zoning regulations and building department requirements also play a role in determining the legality of tiny houses in specific areas. For example, King County requires that tiny houses have a foundation, while other jurisdictions may allow tiny houses on wheels. It is important to research local regulations before building or placing a tiny house.
