It depends on your lot size, zoning, and site conditions. A feasibility study confirms exactly what's possible for your specific property.
We evaluate zoning, market demand, rental income potential, construction costs, and expected ROI to give you a clear recommendation.
Rental income varies by neighborhood and unit size — our feasibility study includes a realistic income estimate for your property.
Typical timelines run 4-6 months for permitting and 5-6 months for construction, depending on project scope.
Long-term rentals are generally allowed. Short-term rentals (such as Airbnb) depend on Seattle city regulations, licensing, and zoning rules. We help you understand what's permitted for your specific property and location.
Every successful DADU begins with understanding your property. Enter your details, and we'll review your property to help you understand the best next step.
