I live in a development in Talbot County where everyone has at least 2 acres per house, but only 3 properties are allowed to have horses. It was designated this way when the property was developed in 1974. Only planning and zoning can give you the answer that you seek, however you can always petition for a varience. Will you get it? You never know, but it is worth a try. Good luck, if I can be of any help, please give me a call..
