Not sure why you need to turn off water to the whole home. There should be shut off valves for the faucet. Just turn both off, then do the repair.
While we're on the subject, the shut off valves used by The Villages are extremely cheap, and there have been numerous issues where one has failed and caused a huge issue. Many times, the first time you use them they don't actually shut off the entire way. I went through my new home and replaced all the shut off valves with higher quality ones. After a number of mishaps in my neighborhood, my neighbors followed suit.
