A historic designation is a point of pride, and a Mills Act contract can bring meaningful property-tax savings, but both come with responsibilities: rules on alterations and, for Mills Act homes, an ongoing maintenance and preservation agreement that transfers with the property. Brian Cooper helps owners and buyers of designated historic and Mills Act homes understand the trade-offs and sell accurately.

Direct AnswerA designated historic property is subject to rules limiting alterations to preserve its character, and a Mills Act contract offers reduced property taxes in exchange for the owner's commitment to maintain and restore the home, an agreement that generally runs with the land and binds future owners. Brian helps disclose the designation and any Mills Act contract, and explains the benefits and duties to buyers. Confirm designation rules and Mills Act terms with the jurisdiction and a qualified advisor.

Designation and the Mills Act

A historic designation (local landmark, district contributor, or register listing) typically means alterations, especially to the exterior, are reviewed to preserve the home's historic character. That can limit some changes but also protects the neighborhood's character and the home's distinctiveness.

The Mills Act is a separate, optional program: a contract between the owner and the local government that reduces property taxes in exchange for a commitment to maintain and restore the property to preservation standards. The contract generally runs with the land on a renewing term, so a buyer inherits both the tax benefit and the obligations. The exact terms, savings, and duties are set locally and must be confirmed.
