Is there a minimum clearance above crawl space dirt requirement in the building code for California for a gas line? I know it has to be clear of the dirt but how far?

Hello RGC,

Hello RGC,

A sleeve with its own protection against corrosion should be provided through the foundation wall and extend
Into the crawl space at least 2 in. (50 mm) from the foundation wall face and at least 18 in. (0.46 m) outside.
The sleeve should be cemented tightly in the foundation wall with cement grout or expanding cement.
A second pipe sleeve extending 2 in. (50 mm) above the floor over the crawl space should also be provided.
Seal the space between the gas pipe and the wall and floor sleeves with cement grout to prevent passage
Of gas or water.
