Notes & caveats
Mercer Island distinguishes Non-Structural from Structural interior remodel. The Residential Building Permits page describes the non-structural pathway as covering "Bathroom remodels, kitchen remodels (without removal of load bearing walls)" with "Scope of work limited to the interior not affecting the structure of a building." Cabinet/countertop/finish work alone is exempt under MICC 17.14.010 §105.2: "Painting, non-structural wood and vinyl siding, papering, tiling, carpeting, cabinets, counter tops and similar finish work, provided that existing, required accessible features are not altered." The Structural pathway applies if beams, posts, or lateral resistance elements are affected.
