I lived in a Christopherson home behind Costco for a year or so. I was renting with a few friends. It seemed they cut as many corners as possible building these homes. We had about 10 feet from the back of the house to the fence. And about 3 feet side yards on both sides. All the houses on our block had the same look and the next street had all the exact same houses. The corners in the houses were made of just sheetrock with no support inside. Very easy to ding or crack if furniture is coming through.
