I doubt it. I was watching some show on HGTV and they had the people on who now own the FoTB house. They had to do serious remodeling and work after purchasing it -I guess it was a mess! I seriously doubt they would have let another movie crew come in even though it was one of the reasons they bought the house. I agree it also looks like the Eight is Enough house, but that was never mentioned in the story and I think series are usually done on a production lot.
It was a cute story - they told their realtor they wanted a house like the one on Father of The Bride and it ended up coming on the market.
