State-Level Building Codes and HVAC Legislation in West Virginia

The State of West Virginia adopts a suite of building codes that govern construction, including mechanical and HVAC systems. These codes are established by the West Virginia State Fire Commission and are codified under Title 87, Series 4 of the Code of State Regulations.
