An owner-builder needs to comply with complex gas piping codes but struggles to find clear, authoritative guidance on practical enforcement and inspection requirements for DIY underground gas line installation.

Existing code references are not easy to interpret for DIYers; inspectors give inconsistent feedback; no single source explains how local AHJs apply the code in practice.
