Do you need a permit for a pole barn in Indiana?
Indiana has a state building code administered by the Indiana Department of Homeland Security (IDHS). Since 2009, one- and two-family residential construction falls under state authority. Commercial structures are regulated locally. Indiana Code § 36-7-9-5 provides exemptions for farm buildings used exclusively for agricultural purposes. Most pole barns used as garages, workshops, or residences require a permit from the local municipality or county.
