I see this all the time - bending a flexible gas line improperly.
In fact, I have seen it two days in a row in two different new construction final walk through inspections!
Installers know, OR SHOULD KNOW, that this is incorrect.
Flexible steel gas lines, called CSST, have very strict bend tolerances! They can snap, easily split and where bent are quite subject to easy damage. Severe bends cause pressure reduction and gas back up. And all the manufacturers say not to bend the tubing too many times.
All the instruction manuals for ALL of the flexible gas tubing manufacturers have pretty much the same criteria. This is the link to the manufacturer of the above tubing. See page 17.
The minimum bend radius on the tubing above is 3". More is fine, but less than 3" is NOT.
The fact that I am seeing this more and more indicates to me that builders are hiring installers who do NOT know what they are doing.
My recommendation: the above was approved by the County likely because it wasn't seen. Home inspections on new construction have a far, far different view of a house than the County or other jurisdictional authority providing an occupancy permit. Home inspectors have a good look! Find a bull dog home inspector and get him on the job. New construction inspections are an essential part of the new home buying experience.
