DADUs (Detached Accessory Dwelling Units)
Design, permits, and construction for detached accessory dwelling units — from backyard cottage to full rental property.
Why Build a DADU?
A DADU is a second, standalone home on a single-family lot. In Tacoma, recent zoning updates and Washington's ADU law (HB 1337) have made DADUs more accessible than ever — more lots qualify, fewer parking requirements, and faster permitting.
- Rental income — long-term or short-term
- Multi-generational living — housing for aging parents or adult children
- Guest housing — separate, private space
- Property value — well-built DADUs reliably increase home value

How long does a DADU take to build?
Typically 6–10 months from design through certificate of occupancy.
How much does a DADU cost in Tacoma?
Costs vary by size and finish. We provide detailed estimates after an initial consultation.
