We have deep experience navigating the specific DADU and ADU permitting requirements for Seattle and surrounding Puget Sound municipalities.
How much does it cost to build a DADU in Seattle?
The cost varies based on size, complexity, and finishes. We provide a detailed, transparent estimate after our initial consultation and design discussion.
How long does the DADU permitting and construction process take?
Timelines depend on project scope and municipal review periods. Typically, you can expect the entire process to take 6-12 months from design to completion.
Can you match the DADU's design to my main house?
Absolutely. We specialize in creating custom designs that complement the architectural style and materials of your existing home for a cohesive look.
What is the difference between an ADU and a DADU?
An ADU (Accessory Dwelling Unit) is attached to your main house—think basement apartment or in-law unit. A DADU (Detached Accessory Dwelling Unit) is a separate structure on your property, commonly known as a backyard cottage or granny flat.
