Yes, it is allowed, but ...
From the 2006 IRC. (underlining is mine)
- P2603.5 Pipes through footings or foundation walls. A
ny pipe that passes under a footing or through a foundation wall shall be provided with a relieving arch; or there shall be built into the masonry wall a pipe sleeve two pipe sizes greater than the pipe passing through.
Passing through a foundation wall - a relieving arch or a sleeve two pipe sizes larger.
Passing under a footing - a relieving arch.
