A formal agreement, generally known as a Mills Act or Historical Property Contract, is executed between the local government and the property owner for a minimum ten-year term. Contracts are automatically renewed each year and are transferred to new owners when the property is sold. Property owners agree to restore, maintain, and protect the property in accordance with specific historic preservation standards and conditions identified in the contract. Periodic inspections by city or county officials ensure proper maintenance of the property. Local authorities may impose penalties for breach of contract or failure to protect the historic property. The contract is binding to all owners during the contract period.
