What’s the Difference Between ADUs and DADUs?

Whether you're pursuing a Bellevue ADU conversion or a Kirkland DADU build from scratch, our team — including our own ADU architect on staff — helps you navigate every detail, from permitting and zoning to finishes and final walkthrough.

Why Eastside Homeowners Are Choosing ADUs and DADUs

  • Income Potential – Create passive income by converting an independent rental unit within your property.
  • Living Arrangements for Multiple Generations – Build accommodation for elderly relatives, young people, or guests from elsewhere without compromising their privacy.
  • Property Value and Versatility – A DADU or an ADU increases living space and value for your property, which is particularly useful in markets such as Bellevue and Kirkland.
  • Maximizing Available Space – Convert your existing garage, basement, or land into an additional living space.
