ADU & DADU Construction in Edgewood, WA

ADU & DADU Construction in Edgewood, WA

Edgewood is hands-down the best area I serve for detached ADU construction. The lots here are big. Many properties along Meridian Avenue, near Surprise Lake, and in the neighborhoods off 24th Street sit on half an acre to a full acre. That kind of space makes a detached backyard cottage straightforward to design and build without eating into your usable yard. I have worked on Edgewood properties for years and know the terrain, the soil conditions, and the permitting requirements that come with building on these larger parcels.

Most of my Edgewood ADU projects are detached units in the 600 to 800 square foot range. At that size, you get a true one-bedroom home with a full kitchen, bathroom, living room, and covered entry. These builds run $195,000 to $400,000 depending on finishes, and the larger lot sizes in Edgewood mean I have flexibility in placement, orientation, and design that tighter urban lots do not allow. I typically build on crawl space foundations in Edgewood because the terrain often has grade changes that make slab work impractical. For homeowners who want a smaller footprint, I also build studio-style ADUs in the 400 to 500 square foot range starting around $155,000. A finished ADU in Edgewood rents for $1,500 to $2,000 per month depending on size and quality. My ADU construction page has the full rundown on how I build these units from foundation to finish.

Edgewood falls under Pierce County for permitting, and I handle all ADU applications through Pierce County Planning and Public Works. Washington's HB 1337 requires every jurisdiction to allow at least 2 ADUs per residential lot, and Pierce County has updated its rules accordingly. The big factor in Edgewood is septic. Many properties here are on septic systems, not municipal sewer. Before I design your ADU, I review the septic as-built and coordinate with the Tacoma-Pierce County Health Department to confirm the existing system can handle the additional load, or whether an upgrade is needed. I have navigated this process on multiple Edgewood properties and know exactly what the health department requires before they sign off.

If you are sitting on a half-acre or larger Edgewood lot and want to generate rental income, house a parent, or build a home office separate from the main house, a DADU is the way to go. Call me at (253) 392-9266 or request a free estimate. I will evaluate your lot, check septic capacity, review setbacks, and provide a fixed-price proposal for the complete project.
