Do I need a permit for shed or accessory structure in Unincorporated Logan County?
Unincorporated Logan County does not issue residential building permits. Logan County has no planning, zoning, permitting, or inspection requirements in unincorporated areas, except floodplain regulations administered by the county floodplain administrator. Guthrie and Crescent issue permits inside their city limits.
The requirements below come from Oklahoma rules and describe the standard the work must still meet. They are not a statement that Unincorporated Logan County will issue you a permit.
It depends. Whether shed or accessory structure needs a permit in Unincorporated Logan County comes down to the details of your project.
The Oklahoma-adopted 2024 IRC exempts one-story detached accessory structures of not more than 200 square feet from a building permit, but the exemption does not cover storm shelters (R105.2, Building item 1). A permit exemption does not authorize work that violates the code or any other local law or ordinance, and wiring a shed is not covered by the building exemption (R105.2). State law does not require a State Fire Marshal permit for a single-family home, duplex, barn, shed, or attached carport in an unincorporated area of a county (74 O.S. 324.11(C)); a county permit applies only where that county has adopted a building code. OUBCC adopted IRC Chapter 1 only to the extent it does not conflict with a local jurisdiction's lawful administration of the code (OAC 748:20-6-6), so the local office's own permit and exemption list controls.
