A question for home builders, land developers, or real estate experts.?
Answers:
Attached dwellings that are classified as single family residences is misadvertising. However there are certain cases in which detached dwellings or "townhouses" are classified as condo's. Condominiums have to be incorporated as a condo, with bylaws & a disclosure packet given to residents/purchasers.
Developers have more control over what's "acceptable" in a condo. For example you can set up your condo to include outlawing "For sale" or "For rent" signs displayed in visible areas such as windows. This is substantially easier and more feasible than trying to change or add deed restrictions. You also have the ability to fine or issue tickets to residents not adheering to condo bylaws. Don't forget the monthly condo fees that are assessed!
Much of this answer is limited to Virginia laws.
Other answers:
I think a lot of this would depend upon the zoning.
Also, the type of ownership (which may be determined by the zoning, actually)... a tract of homes as you described being classified as condo's... I would expect ownership would mean the home itself... and not the land it was on. The land would belong to everyone, I would think.... no individual property lines...that probably means that the 'condo' owners pay a membership fee for maintenance of the lawns, etc.
