Are Tiny Houses Legal in Washington State? Exploring the Regulations and Restrictions
Tiny houses have become increasingly popular in recent years, with many people seeking a simpler, more affordable lifestyle. However, before investing in a tiny home, it is important to know whether or not they are legal in your area. In Washington State, the laws and regulations surrounding tiny houses can be confusing and difficult to navigate.
Fortunately, there are resources available to help those interested in tiny homes understand the legal landscape in Washington State. For example, the State Building Code Council has adopted Appendix Q, which provides specific regulations for tiny homes on a foundation. Additionally, Senate Bill ESSB 5383, which went into effect in 2019, defines tiny homes and requires the Building Code Council to write building codes for them. However, it is important to note that regulations may vary by city, town, or county, so it is essential to research local laws before building or purchasing a tiny home.
Legality and Zoning Regulations
Washington State Building Code and Appendix Q
Washington State has adopted Appendix Q Tiny Houses, with amendments, effective from July 1st, 2020. The state building code council has also written building codes for tiny homes, as mandated by Tiny House Bill 5383, which became effective on July 28th, 2019. These codes ensure that tiny homes are built safely and meet certain standards.
Appendix Q provides specific regulations for tiny homes on a foundation, which includes requirements for ceiling height, loft space, and stairways. It also covers the minimum size of the home and the materials used for construction. The building codes for tiny homes are enforced by the Washington State Department of Labor and Industries (L&I).
Local Zoning Laws and Approval Process
While the state has adopted Appendix Q, local jurisdictions set their own zoning regulations for tiny homes. It is important to check with the local building department to determine if a tiny house is allowed in a particular area. In some cases, a permit may be required to build a tiny home.
In King County, for example, tiny homes must have a foundation and be at least 220 square feet in size. The county also requires that the tiny home be located on a lot with an existing primary residence or that it be used as an accessory dwelling unit (ADU).
Tiny House Communities and RV Parks
Tiny house communities and RV parks provide another option for those looking to live in a tiny home. These communities offer a place to park a tiny home and often include amenities such as water and electricity hookups.
However, it is important to note that not all RV parks allow tiny homes and some may have restrictions on the size and type of tiny home allowed. Additionally, property taxes may be higher for a tiny home located in an RV park compared to a traditional home.
Overall, while tiny homes are legal in Washington State, it is important to research local zoning regulations and the approval process before building or parking a tiny home. By following the state building codes and local zoning laws, individuals can ensure that their tiny home is built safely and legally.

In order to obtain certification, tiny house owners must submit a tiny house plan approval & insignia request form to the L&I. Once the form is approved, the tiny house owner can place an insignia on the tiny house to indicate that it is certified. The L&I also requires notification to the local enforcement agency when a tiny house is placed on a property.
