What Is an ADU or DADU?
Accessory Dwelling Units (ADUs) and Detached Accessory Dwelling Units (DADUs) are secondary living units on a residential property. They’re a smart way to expand livable space without moving or adding onto the main house.
Types of ADUs:
- Attached ADUs (AADUs): Built into the existing home — common examples include basement apartments, attic conversions, or garage studios.
- Detached ADUs (DADUs): Standalone Seattle backyard cottages, also called garden suites, lane homes, or tiny homes.
Whether you're building a compact ADU cottage or a two-story backyard DADU, these units offer exceptional flexibility.
Why Build an ADU or DADU in Seattle?
Homeowners across Seattle are adding ADUs and DADUs to solve space challenges, support loved ones, or generate income — all while staying in the homes they love.
Benefits of ADU/DADU Construction:
- Multigenerational Living: Keep family close while maintaining independence.
- Rental Income: Generate steady income from long- or short-term tenants.
- Increased Property Value: ADUs and DADUs offer an excellent return on investment.
- Sustainable Living: Small, efficient, and eco-friendly housing aligned with urban infill goals.
- Flexibility: Use your ADU in backyard as a home office, guest suite, studio, or long-term rental.
