Looking to expand your home’s potential in a smart, stylish, and income-generating way?

Whether you're dreaming of a backyard cottage, a rental unit, or a private space for family, we’re here to make your vision a reality—while keeping you compliant with Bellevue ADU rules.
What Are ADUs and DADUs?
ADUs and DADUs are self-contained living units located on the same lot as your primary residence.
- ADUs (Accessory Dwelling Units) are usually attached to or located within your existing home (e.g., basement or garage conversions).
- DADUs (Detached ADUs) are standalone structures, such as backyard cottages or carriage houses.
These additions are ideal for multigenerational living, long-term rentals, guest accommodations, or work-from-home studios.
