Following is an excerpt from Questions and Answers on: Condos & Townhouses:

      Q: What's the difference between a condo and a townhouse?

      A: Condo unit owners own the inside of their units. Townhouse owners own the complete unit, including exterior surfaces and the land on which the unit is built. Every condo or townhouse development also has "common areas" of the property (recreation areas, sidewalks, parking lots, etc.). Condo owners share ownership of the common areas with other owners, while common areas in townhouse developments are usually owned by the homeowners' association for the benefit and use of unit owners.
