Shirley Abbots pool
It appears that the location for this scene is 361 N Saltair Ave in Brentwood.
I saw it listed in the real estate section this Sunday and it looks exactly like Shirley Abbots house. It is very distinctive.
The pool looks a lot more like the one that had the plexiglass cover on it.
Update: Got around to comparing the ad to the film, pool and house look nothing like the one in the movie. I had only looked at it through earthview before, and the general shape of the pool looked like the plexiglass one, but not the surroundings.
