Are surface parking requirements actually that common? My local codes (in Nashville, TN) [1] don't seem to care how you get your parking spaces as long as you meet the requirements for your building size and expected use, and buildings are frequently built over parking garages in the denser parts of town to maximize land use. Surface parking's still the norm here as you move out towards the suburbs and land becomes cheaper, but that's not a regulatory thing AFAICT-- parking garages are really expensive per-space, so surface parking is the standard here unless there's a good reason to do otherwise.
