The Pritchett-Tucker House was where Mitchell Pritchett and Cameron Tucker lived together with their adopted Vietnamese daughter, Lily Tucker-Pritchett.
This was the house that the least was seen of, as most of the action took place in the living room or Lily's bedroom. Unlike The Dunphy House or The Pritchett House, it only has one floor; the upstairs is open for rental, revealed in Slow Down Your Neighbors. Their floor contained a living room, one kitchen, one bathroom, two bedrooms, and a garage.
It was revealed in "Mistery Date", that Lily's bedroom was previously Mitchell's home office, but they had to give it up for her room. Outside it had both a front and back garden, and Mitchell, Cameron, and Jay built a play castle for Lily in it in "The Old Wagon", and was frequently seen ever since.
The real house is located in Century City. This residence is just down the street from the studio.
