What Are The Current Adopted Kentucky Building Code and Editions:

Kentucky first adopted and began enforcement of the 2018 Kentucky Code (IBC-2015), 2018 Kentucky Residential Code (IRC-2015), and NEC-2017 without amendments on August 22, 2018. However, a grace period was allowed until the beginning of 2019.  Additionally, the state has adopted by reference the 2015 edition of the IMC and the 2015 IECC. The 2012 IFC is utilized for new construction projects. While the Kentucky codes are applicable statewide, enforcement is only mandatory statewide for commercial buildings. Residential buildings must follow the 2009 IECC with amendments.

Applicability (statewide, local, limited): STATEWIDE

State owned building construction projects require review and inspection by the Division of Building Codes Enforcement. For all other commercial projects enforcement of the Kentucky Construction Code is shared between the Division of Building Codes Enforcement and the local government (city or county) building departments. If a local building department does not exist, plans must be submitted to the State Division of Building Codes Enforcement. For one and two family dwellings, enforcement takes place at the local level. If no local building department exists, builders are still required to comply with the Kentucky Residential Code.
