Local Project Overview
Shed Installation · Johnson County, Iowa
Often exempt under 200 sq ft
In Johnson County, a Shed Installation under 200 sq ft generally does not require a building permit. At or above 200 sq ft, a permit is required.
The county's own building permit FAQ states plainly that a permit is not required to construct a detached building 200 square feet or less, limited specifically to a one-story accessory structure used as a tool shed, storage shed, playhouse, or similar use; that same 200-square-foot figure is reused for an entirely different structure type, since a deck that is not more than 30 inches above grade, not attached to the dwelling, and does not serve the main exit door is separately exempt at the identical 200-square-foot size. Iowa City and Coralville, both within the county, generally align with the same 200-square-foot line, though Coralville's own guidance notes it has not yet published a dedicated ADU ordinance page even as it addresses ordinary accessory structures like sheds, garages, carports, and pools. Building permits in Johnson County are handled under the Johnson County Planning, Development, and Sustainability (PD building code (IRC 2024 International R). Local zoning, property-line setbacks, and any electrical or plumbing work can still require separate approval, so confirm the details with Johnson County Building Inspections.

Frequently Asked Questions
What happens if I build a Shed Installation without a permit in Johnson County?
Building without authorization is considered a code violation. The local government can issue a Stop Work Order, forcing you to halt construction immediately. You may be subject to retroactive permit fees (often double the original cost), daily fines, or even a mandate to tear down the unpermitted work at your own expense.
Can a homeowner pull their own Shed Installation permit in Iowa?
Yes. Iowa generally allows property owners to act as their own general contractor under an Owner-Builder exemption. If you take this route, you assume full legal and financial liability and must ensure all work complies with the Iowa State Building Code.
How much does a Shed Installation permit cost in Johnson County?
Permit fees vary by jurisdiction and by your project's valuation, so Johnson County does not publish a single fixed figure. Confirm the exact fee with the local building department before applying.
