Historic Monticello, Georgia Design Guidelines Developed in 2000 through a Certified Local Government grant, the Monticello Design Guidelines were created to assist decision makers — property owners, developers, contractors, and commission members — in developing design solutions which satisfy Monticello’s Historic Preservation Ordinance. The guidelines provide guidance for rehabilitation of both residential and commercial structures as well as direction for new construction and site changes. Monticello Design Guidelines booklets are available free of charge from City Hall.
