Kenmore has the most restrictive dimensional limits in Zone 2 — your shed can't exceed 15 feet on any side, height maxes at 8 feet for flat roofs or 10 feet for pitched, and only one storage shed is allowed in the rear setback area per lot. The city sits at the north end of Lake Washington, so shoreline buffer zones of 50 to 150 feet can eat into your buildable area. Properties outside those buffers get straightforward rules: 200 square feet, 5-foot rear setback, no permit required.
