Weep Holes in Building Foundation Wall

I'm designing a retaining wall that is part of a building foundation, to address the low grade at the exterior of the building. This is not a basement wall. The main interior floor slab-on-grade is a few feet higher than the exterior grade, thus the need for a cast-in-place concrete retaining wall to support the building. In this case, I am wondering if it is typical (or necessary) to include weep holes in the wall. Given that the retained soil side of the wall is under interior space, direct rainwater collection should not be an issue. I suppose we can include the weep holes, just to be on the safe side (to address any potential rises in groundwater, flooding, etc.), but I'm curious if this is conservative, or if weep holes (or some other drainage system) is typical in these situations where the retained side of the wall is interior space. Thanks.
