A local government in Indiana can adopt a historic preservation zoning ordinance that enables it to designate and protect properties of historical and architectural significance. Authority for such local legislation comes from state statute, often called an “enabling act”. Indiana’s enabling act was made law in 1967, under Indiana Code IC-36-7-11. Some forty cities, towns, and counties in Indiana have designated local historic districts and individual landmarks.
To request a COA you will need to go in front of the Historic Preservation Board. You will need to fill out a COA request form, found on the Planning and Zoning Department Page.
