Loads of buildings don't allow (or practically don't allow) cell signals :: nothing stops them from being built. It's active interference the FCC takes a dim view to - passive interference (thick walls, loads of metal, etc) is fine. There's a theater near me that I can get 4-5 bars of LTE outside, 1-2 bars near the doors, 3G just 20 feet inside, and only 1x or a bar of 3G in each screen room. Don't see the FCC dropping the hammer on them because it's the way the building is constructed, not active interference
