The Partridge house just doesn't seem big enough -- they need more bathrooms and just more room in general! Reuben takes Shirley to look at a new, larger house. The Partridge house is home to her, so Shirley doesn't really want to move, but all the kids are very anxious too. They put their house up for sale, with Reuben acting as real estate agent. After a week without even one looker, Reuben and Danny cook up a scheme for open house with the Partridge Family.
