Always Start with Feasibility First.
- Can I actually build on my property?
- What does zoning allow for my lot?
- What will this really cost — and is it worth it?
- What surprises should I be prepared for?
- Does this make financial sense for my situation?

Dozens of Homeowners We've Helped to Make Better Decisions Across Seattle, Bellevue, and Surrounding Area
We've been through this process dozens of times — on lots just like yours, in cities and counties across the greater Seattle and Bellevue area. We know how local jurisdictions interpret zoning codes, what permit reviewers look for, and where projects tend to get delayed or derailed. That experience means fewer surprises for you. We've already solved the problems most homeowners don't even know to ask about — and we bring that knowledge to every project we take on.
What Homeowners in Seattle & Bellevue Have to Say
Great Experience! From Analysis to Design and approved permits. My project is complete and we love how it came out. Will recommend them to friends.
I wanted a DADU on my property using a pre-approved plan but didn't know how things would work. DADU Solutions came up with a site analysis and fit study for the DADU. They also helped to submit for permit with the pre-approved plans. The job is completed and I'm very happy with the whole process.
