Alabama adopted the 2009 International Residential Code with the following modification: Jurisdictions that did not have a residential building code in effect on March 9, 2010 must begin enforcing the Alabama Energy and Residential Code (AERC) by October 1, 2012. Jurisdictions that already had a code in effect may continue to enforce that code. However, if they choose to update their code, they must adopt the AERC. No jurisdiction can mandate home fire sprinklers with the exception of municipalities that had adopted and were enforcing that provision prior to March 9, 2010.
