- 1,200 sq ft
Area capacity is a starting point, not proof that an ADU fits. The sample explains what to confirm next.

Detailed local research is available for Beaux Arts Village, Bellevue, Bothell, Clyde Hill, Hunts Point, Issaquah, Kirkland, Medina, Mercer Island, Newcastle, Redmond, Sammamish, Seattle, Yarrow Point, and Woodinville.

After you submit
Keep your permit from being forgotten.
Every extra day can cost real money. On a $2 million home, carrying costs can approach $400 per day.
Architects and city reviewers manage many projects, so a missed handoff can sit longer than anyone realizes. The free tracker checks Bellevue, Kirkland, and Seattle permits every day. It alerts you when the public record changes and when nothing has changed for long enough to deserve attention, so you know when to nudge the city or your architect before the permit gets forgotten.

Example assumes a $2 million home with 20% down: $96,000 loan interest + $24,000 opportunity cost on the down payment + $12,000 property tax + $6,000 insurance + $6,000 utilities = $144,000 per year, or about $395 per day. Actual costs vary.

Common questions
Know what the tools can and cannot answer.
What does a feasibility study tell me?
It shows what may fit on the lot, what could limit your plans, and what you should confirm before buying the property or paying for design.
Is the study an official city answer?
No. It is an early review of public information. A survey, title records, site studies, your project team, or the city may change the answer.
What does permit monitoring do?
Build Eastside checks the public permit record every day until issuance and emails you when it changes. For Bellevue and Kirkland, it can also flag when a review appears stalled and tell you when it may be worth nudging the city or your architect so the permit does not get forgotten. Seattle alerts use reliable published status and milestone changes.
How much does Build Eastside cost?
Everything is free. Feasibility studies are limited to one per month. The unofficial price is useful feedback and a recommendation to a friend. Build Eastside's accounting department accepts both as legal tender.
