The Mills Act in Coastal Orange County: Preserving History While Saving on Property Taxes

If you’re a homeowner or real estate investor in Coastal Orange County, you’ve likely heard of the Mills Act—California’s leading financial incentive program for the restoration and preservation of historic properties. From Laguna Beach to Newport Beach and San Clemente, this program not only safeguards architectural heritage but also offers substantial property tax savings.

What Is the Mills Act?

The Mills Act is a California law that allows cities and counties to enter into contracts with owners of qualified historic properties. In exchange for preserving and maintaining their homes, owners may receive a significant reduction in property taxes—sometimes up to 50% or more.
