Additional Information



    Beginning July 1, 1980, the design, direction, construction, and alteration of any building was required to satisfy Chapter 39 of 57-39-21 Energy Efficiency Standards for Buildings (a state energy code based on the 1997 MCEC). The state does not allocate money for municipalities to hire inspectors. The utilities have some incentives for insulation and increased efficiency equipment. Attempts to update the code to the 1992 and 1993 MEC failed to pass the legislature in 1994 and 1997, respectively.

    • Current adoption activity includes the passage of legislation in 2013 authorizing the adoption of 90.1-2010, but the Mississippi Development Authority has not yet taken steps required to formally adopt the code under the state’s Administrative Procedures Act. In 2019, the governor signed legislation extending the repealer on the 2013 statute authorizing 90.1-2010 until 2023.”

    Current adoption activity has taken place to include the adoption of ASHRAE 90.1-2010 effective July 2013.

    Adoption Process

    “Mississippi has no set schedule to update their energy code. State Level: Anyone may submit legislation. It must pass through committee and be voted upon by both chambers of the legislature. Before becoming a law, the governor must sign the legislation. To formally adopt the code, the Mississippi Development Authority (MDA) must take steps required during the rulemaking process under Mississippi’s Administrative Procedures Act. The existing law does not mandate enforcement by localities, and any revised code will probably require adoption by local jurisdictions. To adopt the code at the local level, the local government must adopt it through a vote of the city council or county commission. Depending on the form of government, the mayor may be required to sign the law.”

    Enforcement Process

    For state-owned and -funded buildings, the design professional works with the building commission to establish compliance. For other buildings, local units of government enforce the code through the normal inspection process. If local governments adopt the energy provisions of the Standard Building Code (SBC) (Appendix E of the SBC), enforcement is then accomplished through the permit/inspection process for new construction and additions. Depending on the size of the local government unit, the same individual may be responsible for performing plan reviews and inspections. As of mid-1998, 20 of the state's 82 counties adopted the SBC.

    Compliance Process

    Compliance for state-owned buildings is verified by the Bureau of Building. Other buildings are subject to enforcement by local authorities. For state-owned or -funded buildings, the Bureau of Building reviews plans and specifications to ensure compliance. For other buildings in jurisdictions that have adopted the state code, plan reviews and inspections are typically used to show compliance through the normal permit process. After successfully completing this process, the building department issues a certificate of occupancy.
