I am planning to apply for a permit for an addition at Redmond, WA, and would like to confirm the feasibility of the proposed project before proceeding with the formal application. I have attached some sketches outlining the proposed addition. Before finalizing the design, I would appreciate guidance on the following: Impermeable Surface Limitations – Compliance with maximum allowable impermeable surfaces for the lot. Setback Requirements – Clarification on required setbacks from property lines for the addition. General Feasibility – Any zoning or code restrictions that may impact the approval process. I need someone to review the attached sketches and provide preliminary feedback regarding permit feasibility?
