One-level, two-bedroom detached ADU
A bright, efficient two-bedroom detached ADU designed to feel open, comfortable, and easy to live in. Cedar Grove features a spacious great-room layout with a full kitchen, dining area, and living room—plus two true bedrooms and a full bath, all thoughtfully arranged to minimize wasted space.
With a welcoming front porch and a rear patio for outdoor living, this plan is a great fit for long-term rental income, multigenerational living, or homeowners who want a backyard home that feels complete—without going oversized.
Pricing
Backyard homes are priced as five packages, from $297,049. See the packages and prices →
2026 proposal prices. Each package price includes construction, the builder’s fee and design & engineering; permits, utility and connection fees, and sales tax are extra. A fixed price for this plan on your lot comes after a site visit and design. Seven to fourteen months from design to move-in.

What’s Included in the Seattle DADU plan set?
This plan set provides the core drawings needed to define the layout and exterior design so you can move forward with pricing, planning, and permitting.
Typically included:
- Floor plan layout and dimensions
- Exterior elevations
- Core architectural details needed to price and permit the build
Still required for permitting (site-specific):
You’ll still need a site plan, utilities/connection details, and completed permit paperwork based on your jurisdiction’s requirements. We can help identify what’s needed for your lot and coordinate next steps.
Exclusions
Not in the package price: permit fees, utility and connection fees (sewer, water, power), and sales tax. Site conditions a desk can’t see — slope, soils, tree protection, a long sewer run — can change the price after the site visit. Renderings may show options that aren’t in the standard package; the written scope for your project is what counts.
