Local Project Overview
Shed Installation · Bonneville County, Idaho
Often exempt under 120 sq ft
In Bonneville 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.
Idaho Falls, the county seat, lowers the statewide 200-square-foot shed exemption codified in Idaho Code §39-4116 down to just 120 square feet within its own city limits, a stricter local standard than the state's broader property-rights-oriented default; the city's exemption list also carves out fences as a notable exception that is never exempt, requiring a flat $5 fence permit for any new fence construction regardless of height or size. The city's building-permit jurisdiction is expressly limited to land within Idaho Falls city limits and does not cover unincorporated Bonneville County or the neighboring city of Ammon, both of which instead apply the more generous 200-square-foot state-law figure directly. Building permits in Bonneville County are handled under the City of Idaho Falls Building Department (largest city; uninc building code (IRC Idaho Code §39-4116 ). Local zoning, property-line setbacks, and any electrical or plumbing work can still require separate approval, so confirm the details with Bonneville County Zoning & Building.

Permits for sheds often depend on square footage and whether the structure is permanent.
Code Compliance & Inspections
Because of severe winter weather in Idaho, any exterior structures or footings must be set below the local frost line to prevent shifting, as mandated by the Idaho State Building Code.
Zoning & Cost Factors
Idaho generally favors property rights with relaxed state-level oversight, meaning agricultural zoning often dominates outside of major hubs like Boise. Fortunately, Idaho maintains relatively builder-friendly regulations, keeping base permit fees competitive.

Frequently Asked Questions
What happens if I build a Shed Installation without a permit in Bonneville 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 Idaho?
Yes. Idaho 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 Idaho State Building Code.
How much does a Shed Installation permit cost in Bonneville County?
Permit fees vary by jurisdiction and by your project's valuation, so Bonneville County does not publish a single fixed figure. Confirm the exact fee with the local building department before applying.
How long does it take to get a Shed Installation permit in Bonneville County?
Processing time in Bonneville County varies by season and current application volume at the building department; contact Bonneville County Zoning & Building for a current estimate.
