It seems like they usually clear the top of a building by at least 40 feet. But there's a tower crane working on a building in Austin right now that is clearing it by like 90 feet because there's another building under construction across the street, and I guess they have to clear that crane. But I was wondering if they have a minimum clearance requirement.

I was on a job building a 14 story building, by the time we had put on the roof it was real close to the crane. I got a 5 step ladder, put it on the roof and greased the jib from the ladder instead of climbing 50 meters straight up. Always had to slew around the building even with empty chains. You can see the height difference in the 4th pic down, unfortunatly picture does not do complete justice, gap between jib and roof is only a couple of meters.
