[EADGBE]

Most newer buildings being built (though those are hard to find, sometimes) always have a hookup available.

In my apartment hunting, I usually found that apartments which lacked a hookup were also built before it was a norm to have such a thing.

Seeing that American landry is almost entirely vented drying, a dedicated space of 30 square feet with an outside vent, sewer drain (and vent) and hot and cold spigot are nearly required. It's easy to see why so few old apartments have in-unit w/d hookup.
