Why Build a Backyard Guest House?

Our guest house structures are fully insulated, climate-controlled, and designed for year-round use in the Pacific Northwest. With customizable layouts and multiple model sizes, you can create a space that feels cozy, functional, and perfectly tailored to your yard.

Backyard Guest House FAQ
Does a backyard guest house require a permit?
It depends on your city. Many Greater Seattle cities exempt one-story detached backyard buildings up to 200 sqft from a building permit. Seattle is stricter and exempts only storage-type sheds up to 120 sqft of roof area, so a guest room there needs a permit. Electrical work always needs an electrical permit. We check the rules for your address and handle the permits.
Can guests use the space comfortably year-round?
Yes. Our guest houses are fully insulated and include heating and cooling options, making them comfortable through all Pacific Northwest seasons.
Can a backyard guest house include a bathroom or kitchenette?
Yes—but that moves the project into ADU or DADU territory. If you want plumbing, we’ll guide you toward the right ADU solution and handle all required permits and plans.
What size guest house fits in most backyards?
Most properties can comfortably accommodate a 120–200 sqft guest room. We evaluate your yard layout, available space, and local setback requirements to recommend the ideal size.
What features make a guest house feel comfortable?
Proper insulation, climate control, natural lighting, durable flooring, and thoughtful electrical layouts all contribute to a cozy, welcoming space.
Can I convert a backyard guest house into an ADU later?
In many cases, yes. We can design your guest house with future ADU expansion in mind. Plumbing, utilities, and foundation upgrades may be needed later.
