Shed permit rules in Kane County, IL — also referred to as storage shed, backyard shed, or accessory building regulations — set size limits, setbacks, and when a building permit is required.
In unincorporated Kane County, detached accessory buildings such as sheds are limited to a combined 900 square feet on lots of two acres or less, and 1,800 square feet on lots between two and five acres. Sheds must meet yard setbacks; a building permit is required.
Under Zoning Ordinance 25-5-9-5, on lots of two acres or less all detached accessory structures together cannot exceed 900 square feet of floor area under roof; on lots over two but under five acres the combined cap is 1,800 square feet. Section 25-5-9-2 requires detached accessory buildings to be no closer than five feet to any other building, bars them from required corner-lot side yards, and prohibits them from occupying more than 25 percent of a required yard. No accessory building may be built before the principal house. Kane County requires a building permit for sheds; verify exact setbacks with the Development Department.
Oversized, unpermitted, or improperly located sheds are zoning violations subject to stop-work orders, mandatory removal or resizing, and daily fines under Chapter 25 enforcement.
