Design guidelines were established to provide guidance on compatible changes to and treatment of existing historic district properties, as well as to assist in the development of sensitive new construction. The Secretary of the Interior's Standards for Rehabilitation are used as the basis and reference for Lakeland's Design Guidelines. Design Guidelines provide standards by which the Historic Preservation Board's Design Review Committee and staff evaluate whether alterations to existing buildings and new construction in the historic districts are architecturally appropriate. A Certificate of Review will be granted if the proposal is consistent with the Design Guidelines, and must be granted prior to the issuance of building and demolition permits. These Standards and Guidelines are used by the Historic Preservation Board to evaluate all exterior alterations, demolitions, and new construction within the City's seven historic districts.
