What’s Included in the Seattle DADU plan set?
This plan set provides the core drawings needed to define the layout, exterior design, and overall construction intent—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 the next steps.
