Your Guide to Tiny Homes in Seattle

If you’re wondering on whether Seattle is a good city to settle in with a tiny home, the short answer is yes. Of course, like with most states, there are still some tiny home-specific regulations to follow that differ from a regular-sized house. Luckily, we’re here to tell you all about the things to look out for before you start building the tiny home of your dreams in the Emerald City.

The Basics

Many have taken up interest in tiny homes in recent years in Seattle, due to its sustainability factors and becoming a reasonable solution to the housing affordability crisis. It costs significantly less than a conventional house and it’s an innovative way to change up your lifestyle.

Because of this, setting up a tiny house in Seattle and surrounding areas has become easier than ever. Some cities and counties allow tiny house villages, where tiny house on wheels (THOWs) can park long-term in the same vicinity. This is due to the trend of tiny homes becoming more and more acceptable and popular. In turn, this reduces restrictions of THOWs around the state of Washington.


Prices can be anywhere between $40,000 to $100,000 depending on the floor plans, materials, and amenities. Bear in mind that this won’t include the price of land, if you choose to build a permanent tiny home on a foundation.

Before building, it’s essential that you get approval for your tiny house. This often entails submitting the plans of your tiny house to the local building department. Getting approval also depends on where the house is built. Make sure to contact your local building department to build lawfully and book an L&I electrical inspection.

Certain cities won’t permit tiny houses unless they comply with standard local size requirements and building costs. On the other hand, rural areas in the state may be more accommodating when it comes to the requirements, but it pays to always check with your local zoning for the most up-to-date regulations.
