I am 62 raising my 5 yr old granddaughter and I have a 25 yr old son who has disabilities but high functioning. Is this acceptable in a 55 plus community?

I do not think so. It is not a disabilities issue, it is the ages of your child and grandchild. Bay's End has management office on site, best to inquire there.

Best to speak with the management

Yes only 1 person I believe has to be 55. Call and give a chuck. Their lot rent is close to $700 then all utilities, and the price of your home.
