What the report checks

Your city's rules, on your parcel.

From public records

Units, size, height, setbacks, coverage, parking, flood, slope, sewer.

Only on site

Truck access, protected trees, the sewer lateral, easements, your HOA.

Sizes and costs

400 to 1,200 square feet. Seven to fourteen months.

Recent proposals ran from about $293,000 to the mid-$400,000s. Your report gives the range for the designs that fit your lot.

2026 proposals, before permits, utility fees and sales tax. A fixed price comes only after a site visit and a design. Construction by United Signature, WA reg. UNITESE790Q3.

Five priced packages

Three quick questions

Do I have to live on the property?

In most Washington cities, no. Your report says which rule your city uses.

How big can it be?

Cities can't cap it under 1,000 sq ft. Your setbacks usually decide first.

Can I sell it separately?

State law says yes, as a condo. The report says whether that's realistic on your lot.

What fits on your lot?

Two minutes to ask. A few hours to know.
