I live in a condo and there aren't very many rules - just basic good manners and common sense. There are only 19 buildings and 72 units - 16 4 units, 2 3 units, and 1 2 units. Whatever you do to the inside of your place is fine - the outside belongs to the Association - although there are no rules about what you can plant in the front or behind your unit. I downsized from a three-story (full basement and two floors) and did not want to have to deal with a yard anymore.
