Townhomes are interesting because that isn't always true. I live in a very large townhome complex much of which is built on top of an underground parking garage. There dozens of townhomes here, intermixed with condos as well. There isn't any land for me to put a tree on, there is a commonly owned green area (a very nice one!) but people can't plant whatever they want there since it is under common ownership. I'd say most of the townhome communities around where I am at are arranged like this. I'm familiar with row houses from traveling to other cities, but I haven't (rarely?) seen anything like that here in the Seattle area. The latest trend is SFHs built on 3000 sqft lots. Honestly at that point, a townhome complex with a common yard seems very preferable.
