How Far down should a Gas Line be Buried when Installing it to a House?

Apr 29, 2026

When installing a gas line to a house, the required burial depth depends on the location and the type of pipe being used, as mandated by International Code Council (ICC) standards. The general guidelines for burial depths are as follows:

  • Protected piping or non-metallic pipe in residential areas: A minimum of 12 inches of cover is required.
  • Under streets or driveways: The line must be buried at least 18 inches deep.
  • Areas subject to vehicle traffic: The line must be buried at least 24 inches deep.

Following these specific depth requirements is critical to prevent hazards such as excavation strikes, physical damage from vehicle impacts, or freezing during winter. In addition to these depths, underground installations must use corrosion-resistant materials like polyethylene and include tracer wires for non-metallic pipes to assist in future locating. For a safe and code-compliant installation, it is recommended to use NATE-certified technicians who are familiar with local building department codes and permit requirements.
