Michelle, Your local government would be the best place to get answers about what you can do on your land according to zoning regulations. Also, there should be a home health care agency in your county that can assist you with getting the help you need. Do you have SSI (suplemental social security income) for your son? Local agencies in your area should be able to assist you with getting the information you will need to get housing for him. Let me know if I can assist you with other information!! My best to you and your son.
