It's been a number of years since I was involved in e911 rollout, but at that time geolocation for 911 was very rough. We were doing this testing in Kansas (I was literally handed a map of every cell sector in the county and a script to read as I called into 911 a hundred times a day from each sector), but accuracy at best was within a block or two. I'm sure technology has improved since then, but the apt complex I live in now in NYC has 25,000 residents over 80 acres. My guess is the closest geolocation they'd get is to a cluster of a couple buildings, which could easily be close to 500 different residences.
