Mike, the issue becomes one of the fact that if he's renting he doesn't own the building and doesn't have the "right" to mount an antenna or run any cables into his apartment without the landlord's approval. Most landlords don't easily let you punch holes in their buildings, but some will allow it so he should check his lease and talk to the landlord.
ANother option that I've seen in a number of apartments and condos (again where you don't own the exterior wall -- part of the common areas and require approval from the association) is that many people put their dishes on the balcony and mount them in a way that leaves no damage when they're removed. If you don't have the SW exposure, then, that idea doesn't work real well.
So to get back on topic, the FCC Fact Sheet assumes that you own the property the antenna is being mounted on, such as home that has homeowners association docs that prohibit outside antennas (as does mine). I used that to put up both my D* antenna and OTA antenna, telling the Association that they could not prohibit it by law and quoted that fact sheet.
