Commercial plan review, enforcement and inspection service covers most commercial buildings with limited exceptions. Enforcement of codes on those buildings that are exempt from the State plan review are not exempt from local permitting requirements. Enforcement (plan review & inspection) of one and two family dwelling codes is handled at the local level only.

State inspectors exist only for Elevators and Boilers/Pressure Vessels.

 Local jurisdictions are not allowed to adopt or enforce their own electrical code unless it has been approved by the Commission. The Office of the State Building Commissioner inspects all buildings and structures in areas without approved local building departments.

The State of Indiana has adopted the 2014 Indiana Building Code (in reference to 2012 International Building Code, IBC), the 2005 Indiana Residential Code (in reference to 2003 International Residential Code, IRC), the 2014 Indiana Mechanical Code (in reference to 2012 International Mechanical Code, IMC), the 2009 Indiana Electrical Code (in reference to National Electrical Code, NFPA 70), and the 2012 Indiana Plumbing Code (in reference to International Plumbing Code, IPC).

Indiana state wide building codes are minimum, however it is up to each local jurisdiction to adopt and enforce these code (home rule state).  In some parts of the state residential (one and two family) dwellings are built without plan review or inspection.
