Many management types will attempt to tell you that you can't hang clothes on a line. In nineteen states, such rules are explicitly prohibited by state law: http://www.sightline.org/2012/02/21/clothesline-bans-void-in... . They have the cheeky name of "right to dry states".

A related thing often banned is external over-the-air antennas, protected by US federal law.

Well, the focus in that particular article is on HOA bans, not apartment ones. For instance, the Hawaii law (the first one I clicked on that seemed particularly cut-and-dried) is restricted to single-family homes and townhomes.

"The purpose of this Act is to prohibit real estate contracts, agreements, and rules from precluding or rendering ineffective the use of clotheslines on the premises of [b]single-family dwellings or townhouses[/b]." [0] http://www.capitol.hawaii.gov/session2009/bills/SB1338_CD1_....
