In Austin we have many condo's that have individual garages. There are even "free-standing condos" that look and feel like single family homes, often they have 2-3 car garages. We also have multi-level condos and one story townhomes. The buildings are only limited by the individual developers and the yterrain. Real estate is a very local matter, and its very different from city to city and state to state. If you have questions about your particular property, your Realtor should be able to help you find the answers.
