[quote author="TTTrojan4life" date=1245649916]I have a question that I know many of you will be able to answer. Can I put a manufactured home on an R-2 lot as the second home on the property? If so, I am wondering why it isn't done more often. an 1,800 sq. ft. manufactured home is going for 80,000 at the OC Swap Meet.</blockquote>
It depends.
Some jurisdictions will allow it, and some will not. It will still need to fit on a lot and conform to all the necessary setbacks. Not knowing where you plan to do this, I cannot comment on whether or not it is permissible, but here in California, I rather doubt it.
