Do you have inside information that the developers deliberately used GPS coordinates in homes for that reason? To do this fairly and methodically, they'd have to put a creature in every house and every apartment--better yet, the whole series of creatures--because you never know where all the mobility-impaired kids live.
No, it's not done that way that I know of, nor necessary as the game has the tech to spawn creatures in a radius around the player, making it very easy to be fair without needing a database of house coordinates. It would not surprise me if they do this to guarantee that new players will have something in their immediate vicinity to seek out, as bad first-play impressions are deadly to a mobile game, a big cause of failed player acquisitions. If people turn on the game for the first time, and there is nothing nearby to go catch, a very significant percentage will simply close and delete the app.
The game also lets players put down "lures", which are new creature spawners. As far as I can tell, there are no restrictions on where this can be done yet. I saw a news story the other day about players deploying their lures near Childrens hospitals, so that the sick kids in there would have plenty to keep them busy.
