I'm not sure I understand the question. A townhouse is single-family attached. If you mean to go from a townhouse to a duplex (a property that's on one deed but has 2 separate living units attached side by side, front to back, etc), then I would first check the current zoning of the property. If that doesn't permit duplexes, then you may be looking at a zoning change which can be very difficult to impossible to achieve.
I agree with you Nancy, the question is not clear. It could be that he has a duplex, or what is called here in Chicago a 2-flat.
If you wanted to sell the units seperately, you could do a condo conversion and sell them as condominums, but you'd need a pretty good condo market to make it worthwhile to pick up the costs of conversion.
You need to check with the zoning board to see if zero lot line houses are allowed. It may require a variance to divide this townhouse into two seperate residential units.
