2021 Virginia Fuel Gas Code

The 2021 Virginia Fuel Gas Code is the official state-adopted code that governs the design, installation, inspection, and maintenance of fuel gas systems within the Commonwealth of Virginia. Based on the 2021 International Fuel Gas Code (IFGC) published by the International Code Council (ICC), this code includes Virginia-specific amendments tailored to meet the state’s unique regulatory, climatic, and safety needs. The code includes detailed requirements for materials, components, and testing procedures, as well as mandates for periodic inspection and maintenance to maintain safe operation over time. It sets clear guidelines for sizing and locating piping and appliances, outlines safety measures for fuel storage and handling, and specifies the proper installation of venting systems to ensure safe exhaust of combustion gases.
