Local Project Overview
Shed Installation · Polk County, Iowa
Often exempt under 120 sq ft
In Polk County, a Shed Installation under 120 sq ft generally does not require a building permit. At or above 120 sq ft, a permit is required.
Polk County amended IRC Section R105.2 to a 120 sq ft exemption threshold, stricter than the standard IRC floor of 200 sq ft. The county also changed the fence exemption to 6 ft and moved prefabricated pool exemptions to its own Zoning Ordinance rather than the building code. This differs from the 200 sq ft threshold used in most other Iowa cities. Building permits in Polk County are handled under the Polk County Building Services building code (IRC 2021 IRC (enmienda l). Local zoning, property-line setbacks, and any electrical or plumbing work can still require separate approval, so confirm the details with Polk County Building Inspections.

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.
