Mills Act Program
Historic Preservation Contract


The City of Redlands invites applications from property owners to participate in the city’s Mills Act program, designed to encourage the preservation of historic properties in Redlands.


The Mills Act Program is an economic incentive program statewide in California for the restoration and preservation of qualified historic buildings by private property owners. Participation by the City in the California Mills Act Program was approved by the City Council on November 20, 2012. 

The California Mills Act Program was first enacted in 1972, and grants participating cities and counties the authority to enter into contracts with owners of qualified historic properties who actively participate in the rehabilitation, restoration, preservation, and maintenance of their historic properties. Since the costs of doing so can be high, and ultimately have the effect of prohibiting preservation activities, property tax relief can offset these costs. Thus, the Mills Act program is offered as a strong incentive for property preservation work.  

Additional information about the statewide program is available from the State Office of Historic Preservation, Mills Act Program website (click here), or go to for the California Office of Historic Preservation.

Property Tax Savings

Property taxes are recalculated using a formula in the Mills Act and State Revenue and Taxation Code. The average savings for individual properties under the Mills Act contract is between 20 and 60 percent. The full amount of the tax savings received by the property owners must be used to finance the preservation, maintenance and improvements to the property. If a property owner defaults on the conditions, the City may cancel the contract and the owner would be subject to a cancellation fee.


The eligibility and program guidelines include:

  • Property must be located in the City of Redlands;
  • Property must be privately owned;
  • The property is not currently exempt from taxation; 
  • The property is listed in a Federal, State or City official register pursuant to Calif, Gov. Code 50280.1
    (Note: If the property is not currently designated as a historic resource, then an additional application may be processed concurrently to have the City Council approve its designation and include it in the City’s list of Local Historic Resources to make the property eligible for a Mills Act Contract);
  • Significant features that define the historical character of the property and its buildings have not been destroyed or can be restored based on documentary, physical, or pictorial evidence; 
  • The owner of the property proposes to make significant improvements to the property that will not impact the architectural, historical, or aesthetic integrity of the property; 
  • The property owner agrees to enter into a 10-year contract, and have the contract recorded with the County Assessor; and
  • The property owner agrees to submit documentation every year to the Planning Division that allows the City to conduct an annual review of the work completed and evaluate compliance with the contract.    

Review and Approval Process

After filing an application for a Mills Act contract and all necessary information has been submitted, the application will be reviewed by the city’s Historic & Scenic Preservation Commission for a recommendation to the City Council. The City Council would then hold a public hearing and make a final decision on the Mills Act contract. Overall, the process typically takes about 3 to 4 months (due to the preparation and lead time necessary for public hearings).  

The City may approve up to seven (7) applications per year, consisting of five (5) residential properties and two (2) commercial properties.

Each contract that is approved will include a term of ten (10) years, and will renew automatically each year.

Annual Reporting

 Each property owner with a Mills Act contract will be required to prepare and submit an annual report to verify compliance with their contract. The annual report assures that the property is meeting its obligations to implement the 10-Year Work Plan included in the Mills Act contract.

The Annual Report must include the following: 

  • Brief description of the improvements completed during the previous 12 months; 
  • Photo documentation of work completed during the previous 12 months; and,
  • Copy of all receipts for improvements to verify al costs expended during the previous 12 months.

Annual reports must be submitted to the Planning Division no later than July 31st each year. Annual reports may be dropped off or submitted to the city’s Historic Preservation Officer: Brian Foote, City Planner/Planning Manager.
