ADU & DADU Construction FAQ for Kirkland Homeowners
What is a DADU vs. an ADU?
An ADU (Accessory Dwelling Unit) is a smaller, self-contained living unit on a property with a primary home. A DADU (Detached Accessory Dwelling Unit) is a freestanding structure—a backyard cottage. Seattle allows both types on most single-family lots.
How much does an ADU cost to build in Seattle?
ADU costs in Seattle typically range from $200,000-$400,000 for a DADU, depending on size and finishes. Attached ADUs can range from $100,000-$250,000. Our Passive House ADUs cost slightly more upfront but have near-zero energy costs.
What are Seattle’s ADU rules?
Seattle allows both an attached ADU and a detached ADU (DADU) on most single-family lots—meaning up to three dwelling units on one property. DADUs can be up to 1,000 sq ft. We handle all zoning research and permitting.
Can a Passive House ADU really have near-zero energy costs?
Yes. A well-built Passive House ADU in Seattle’s mild climate can have total heating and cooling costs under $20/month. Many of our ADU clients add a small solar array to achieve true Net Zero.
