When Omar comes back to the abandoned home he's living in; after he looks around to be sure it's safe; he throws a wall switch to turn on the lights.

And since it's marked by the city with a phone number to call for trapped animals; we know it's abandoned. In the other case with people living in abandoned homes electricity was being brought in by extension cords. Since all the meters are removed from homes like these there would be no other way to get electricity into the house.
