Can a condo association ban nudity?

Could you sunbathe in the nude on your own balcony? Not necessarily. In a condominium development, a balcony is not considered private property but common property assigned to your exclusive use - but a common area nonetheless.
Covenants, codes and restrictions (CC&Rs) usually spell out what activities can and cannot be conducted on common property. Some associations prevent people from barbecuing on their balconies or hanging large plants from the railings. However, the larger issue of regulating personal conduct is not so clear-cut. It literally depends on what side of the fence you're on.
If the sunbather can be seen from a public vantage point -- not by someone who must climb a tree or peer through binoculars -- then the rule probably would be considered reasonable, say legal experts.
Incidentally, there are places where nudity is tolerated but again, only out of public view.
