Louisiana HVAC Legislation, Codes, and Guidelines

State-Level HVAC Building Codes in Louisiana

Louisiana enforces a statewide building code known as the Louisiana State Uniform Construction Code (LSUCC). This code is based on the International Codes (I-Codes) published by the International Code Council (ICC). As of the most recent major update effective January 1, 2023, the state has adopted the 2021 editions of the International Codes, including the International Mechanical Code (IMC) and the International Fuel Gas Code (IFGC), which directly govern HVAC installations. Additionally, the state enforces the 2021 International Energy Conservation Code (IECC) for residential buildings and ASHRAE 90.1-2019 for commercial buildings to regulate energy efficiency in HVAC systems.

Primary State Agencies and Boards

The primary agency responsible for the adoption and oversight of these standards is the Louisiana State Uniform Construction Code Council (LSUCCC). The LSUCCC is tasked with reviewing and adopting the state uniform construction code, establishing requirements for the certification of code enforcement officers, and considering amendments to the code to address Louisiana's specific environmental challenges, such as high wind and flood risks. Enforcement of these codes is generally carried out by local building departments, while the Office of the State Fire Marshal also plays a significant role in the review and enforcement of commercial building codes and fire safety standards.
