Provide Your Parents With A Private, Secure Place To Live In Seattle
We all want the best for our parents. After how they cared for us for years, many of us want to return the love by ensuring they have the best, safest place to reside in their later years.
Accessory dwelling units (ADU) and detached accessory dwelling units (DADU) provide a compassionate and sensible alternative to Seattle’s adult living facilities and retirement homes. This way, your parents are close enough that you can help care for them while allowing them to maintain their independence.
Create a comfortable place nearby where you and your loved ones can continue creating beautiful memories together.

Rent Out Your Seattle ADU Or DADU
Seattle is a popular tourist destination with attractions like the Space Needle, Pike Place Market, and the Museum of Pop Culture. And we live in an era where contemporary travelers want to skip the traditional hotel experience and make genuine local connections instead.
Many Seattle homeowners have begun renting their ADU or DADU with vacation rental services like Airbnb to enjoy an additional income stream.
We can help you create the perfect rental space by converting part of your home (like a garage), extending a part of your home, or building an entirely new accessory dwelling unit. Let’s get started on the best option for you!
