How will I find the parking in the Sutton Place neighborhood in New York City if I move there?

Most housing in Sutton Place is the single family home, so if you live in one of those, you'll have a garage. The rest of the housing is luxury apartments and they usually have garages. If you live in one of the few buildings that doesn't, but you live in Sutton Place proper, you can just rent out a spot in a nearby garage. It's expensive (around $500 / month) but so is Sutton Place.
