Ryan Homes is building a bunch of homes nearby. The basement

by a hefty bracket bolted to the wall - a foot or so above grade.

Why are they doing this instead of putting the compressor on
the ground? It seems to me that a lot of noise gets coupled
into the house when it's done this way, plus cost of bracket
and mounting labor. What am I missing?

They do it so you can mow the lawn under the compressor.

Otherwise you have to pick it up every time you want to mow.
