What does Federal Fair Housing Acting mean to condo associations?

Under the Federal Fair Housing Act, Is it breaking any laws or can a Florida Condo Association President make a community rule that no child under the age of twelve can play outside without a parent or adult supervision present when the children are outside. This is not a adult restricted community. Do boards have the authority to dictate parenting? There is nothing in the Doc's that address this issue except to say No bike riding on the grass.
