Shed permit rules in Kent, WA — also referred to as storage shed, backyard shed, or accessory building regulations — set size limits, setbacks, and when a building permit is required.
Kent allows residential sheds without a building permit when 200 square feet or less, under 12 feet tall, and not used for habitation. Larger sheds or any shed with utilities need a permit and must meet zoning setbacks.
Under the Washington State Building Code adopted by Kent, a detached accessory one-story building 200 square feet or less used as a tool or storage shed is exempt from a building permit. Kent generally applies the residential rear/side setback (commonly 5 feet) and a maximum accessory height around 12 to 15 feet depending on zone. The shed may not be closer to the front property line than the main house. Sheds with electricity, plumbing, or gas require separate trade permits regardless of size, and living in a shed is not allowed unless it is permitted as an ADU. Sheds count toward lot coverage and, if over 200 square feet, must have a building permit with an engineered foundation and snow-load-compliant roof. HOAs may impose color, material, or placement restrictions stricter than city code. Sheds within Critical Area buffers typically need additional review or may not be permitted.
