PROJECT PREPARATION01 / SITE + SCOPE
selected Puget Sound communities / ADU and addition site planning
Start your ADU or addition with the property
Access, utilities, drainage, and the existing house shape what can be built. Prepare a parcel-specific project discussion for selected King, Snohomish, and Pierce County locations.
Make the first decisions
A useful starting point for your project
A floor plan does not establish that a structure fits your parcel. This guide helps you assemble a site brief before design and pricing. It does not determine permitted unit count, setbacks, or parcel eligibility.
Utility records are missing
Identify the verification work before estimating connections.
Two layouts look possible
Compare complete site scopes, not floor area alone.
The homeowner’s field guide
ADU and addition site feasibility: the parcel before the plan
Start with the property address and parcel number. Confirm whether a city or county administers the application; a Seattle, Everett, or Tacoma mailing address alone is not enough. Ask for current guidance for your proposed project type. Keep the answer and source with your site notes instead of applying another city’s rules.
