In Mercantile & Assembly occupancies where your number of fixtures requires the Uni-sex restroom; how do you control who uses this room. In particular an Open Mall, under the 2009 Codes and pending 2012 are allowed to have General Public Restrooms. Since the number of fixtures will most likely exceed an aggregate of six, the Uni-sex restroom will be required and such restrooms will be required to have a privacy lock. Now the security/control of the room! You will not want just anyone using the room without some sort of control. People with mischief on their mind could get in lock the door and do whatever without someone to monitor the use of the room. How does the AHJ allow security control of the room?
