Guest houses and ADUs on larger Eastside lots.
A guest house is usually for someone you love: a parent who wants to live close, a grown child, or visitors who stay for weeks. It should be built like the main house, not like an outbuilding. We plan it with the main house in mind, so the two look like they belong together.

How it runs
- Check the lot. Placement, access, utilities and what the city's current rules allow. We link to the city's own guidance rather than restating it.
- Design. With your architect, or with ours, matched to the main house.
- Permit and build. We prepare and track the permit, then build with the same crew and reporting as a full house.
Who this is for
- Parents moving closer who want their own front door
- Families with long-staying visitors
- Owners adding a studio, pool house or office away from the main house
What moves the price
- Size and plumbing (a kitchen and bath are most of the cost)
- Distance from utilities
- Access for materials behind the main house
- Matching the main house's cladding and windows
Rules for your parcel change; we check the current ones and point you to the city's own guidance, such as Seattle SDCI.
Questions
Can I rent out a guest house?
Local rules decide that, and they change. We do not promise rental income or resale value; we can introduce you to people who can advise on your situation.
Do you build small projects?
Guest houses, yes, when they are on a lot where we are also building or have built. We do not take on stand-alone remodels.
Talk it through with an owner before anyone draws a line.
