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.
Most likely yes. Addition or structural alteration usually requires a permit in Oklahoma. Confirm the specifics with Unincorporated Logan County.
Oklahoma law requires a permit from the city, town, or county with jurisdiction before construction or major alteration of buildings covered by the OUBCC codes, and the work must meet the code last adopted by the OUBCC (74 O.S. 324.11(A) to (C)). 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. When an alteration or addition requiring a permit occurs, the 2024 IRC requires smoke alarms (R310.2.2) and, where there is a fuel-fired appliance or attached garage, carbon monoxide alarms (R311.2.2) throughout the dwelling as for new construction; Oklahoma law also requires smoke detectors or their wiring in remodeling of homes that requires a building permit (74 O.S. 324.11a(D)). Oklahoma has no state general contractor license, but plumbing, electrical, and mechanical trades are licensed and roofers are registered by the Construction Industries Board (CIB FAQ).
