The primary regulatory authority for gas installations in most regions is typically the local building code officials. These officials enforce local building codes and safety standards, ensuring that installations conform to safety regulations and are conducted by qualified professionals. Their role includes reviewing plans, granting permits, and conducting inspections to ensure compliance with the code, which often encompasses gas line installations and the safety measures required to prevent leaks, explosions, or other hazards related to gas usage.

In contrast, the other options listed play different roles in regulatory frameworks. The Federal Trade Commission mainly oversees consumer protection and antitrust laws, rather than specific installation regulations. Occupational Safety and Health Administration focuses on workplace safety and health standards, which, while relevant to workers' safety, does not directly regulate gas installation practices in residential or commercial properties. The Environmental Protection Agency addresses environmental issues and pollution control, but it does not specifically oversee the installation of gas piping systems or appliances. Therefore, local building code officials clearly hold the main responsibility for regulating such installations in most areas.
