DADU's in Seattle

Looking to buy, sell, or learn more about DADUs?

So, What Exactly is a DADU?

A DADU (detached accessory dwelling unit), also commonly known as a mother-in-law unit or a backyard cottage, are detached residential structures. They have grown in popularity in the Seattle area as the city has changed their zoning rules to allow for increased density to help combat the shortage of housing.

Why have they become so popular?

  • ​Increase the property value for homeowners
  • Additional income
  • Generational living

    Why Are They Being Called Condos?

    • • WA State Condo Act (RCW 64.34), any property owner can create a condominium on their property per the guidelines.
    • • Condo creation happens at the county level.
    • • A condo plat is recorded and creates property boundaries - similar to a short plat
    • • Allows for the original house and a DADU to be sold separately.
