You’re looking at a Claremont home with a Mills Act agreement, or preparing to sell one. The immediate answer is that the contract can follow the property. A buyer may inherit the preservation work, reporting, fees, inspections, limited public access and renewal terms along with the potential assessed-value benefit.
This is general information and not legal advice. The terms below come from the draft agreement placed on one owner’s request before the Claremont City Council in 2026. An executed agreement may differ, and these terms should not be treated as the terms of every Claremont Mills Act contract.
What was on the Claremont council agenda?
One owner’s Mills Act request was on the council’s October 27, 2026 agenda as item 8.
The Architectural and Preservation Commission reviewed the request on September 9, 2026. It found the scheduled improvements categorically exempt from the California Environmental Quality Act under Section 15331 and recommended that the council authorize the City Manager to execute the agreement.
As of November 4, 2026, the council’s decision was unknown because minutes had not been posted. Check the City of Claremont’s October 27 agenda and attachments and later meeting records for the final outcome.
Claremont established review criteria and procedures through Resolution No. 2000-157 on October 24, 2000. Resolution No. 2009-04 expanded them, and Resolution No. 2012-75 later amended the criteria and replaced both earlier resolutions.
What property and features does the draft cover?
The draft covers a qualified historic property listed in Claremont’s Register of Structures of Historical and Architectural Merit.
It also requires the property to qualify under Government Code Section 50280.1, meaning it is privately owned and not exempt from property taxation. Exhibit B identifies the property’s character-defining elements. Those elements may include exterior and interior features, and the owner agrees to preserve them.
Work must follow Claremont Municipal Code Chapter 16.300, rules of the State Office of Historic Preservation, the United States Secretary of the Interior’s Standards for Rehabilitation of Historic Properties, and the State Historical Building Code.
Before making physical changes, the owner must notify Claremont’s Director of Community Development. Significant exterior building and site changes require prior City review. The same applies to changes involving interior character-defining features listed in Exhibit B. When seeking a building permit, the owner must also tell Building Division staff that the property is under a Mills Act contract.
What ongoing work and access does the owner accept?
The owner accepts a scheduled improvement program, annual reporting, a review fee, inspections and limited public access.
Exhibit C contains the improvement schedule. Under the draft, the cost of those improvements must equal or exceed the property tax savings received during the first ten years. The work and its cost may be divided between two five-year periods.
The maintenance terms prohibit dilapidated, deteriorating or unrepaired structures. They also prohibit visible junk or debris storage, stagnant water or excavations, including pools or spas, and conditions considered unsightly because of their height, condition or inappropriate location.
Each year, the owner must send a letter describing completed improvements, supported by pictures and receipts. The owner also pays an annual compliance review fee calculated from 2.2 hours of staff time at the prevailing hourly rate set by the City Council.
The City, County Assessor, State Parks and State Board of Equalization may inspect the interior and exterior by advance appointment. A mandatory examination occurs every five years.
The owner also agrees to periodic public access for a limited tour or special event coordinated with Claremont Heritage or another community group. The first event may occur approximately five years after the agreement date. Later events may occur approximately once every five to eight years. Claremont Heritage’s Mills Act page describes the program as a preservation incentive and provides its own contact information.
Does a buyer inherit these obligations?
A buyer who takes title to the property would inherit the same rights and obligations under the draft agreement.
The contract says it binds the owner’s successors and assigns in interest or title. It also says every later contract, deed or other instrument covering or conveying the property is treated as delivered and accepted subject to the agreement’s covenants.
After signing, the City records the agreement with the Los Angeles County Recorder no later than 20 calendar days afterward and sends a certified copy to the County Assessor. The owner must give written notice to the State Office of Historic Preservation within six months.
The California seller disclosure guide explains the broader disclosure setting, while the Mills Act contract and its exhibits supply the property-specific terms here.
M. asked us whether buying a home with a Mills Act contract simply meant receiving a lower property-tax bill. She had plans for several exterior changes and had not considered the obligations attached to the historic property. We reviewed the existing contract and maintenance requirements before treating the tax benefit as part of her purchase calculations.
How do renewal and nonrenewal work?
The agreement starts with a ten-year term and automatically adds one year on every anniversary date.
That annual addition continues unless the owner or City gives notice of nonrenewal. The owner’s notice must be delivered at least 90 days before the renewal date. The City’s notice must be delivered at least 60 days before that date. An owner may protest the City’s notice in writing to the City Council.
Nonrenewal does not end the agreement immediately. After notice, the contract runs through the remaining term. Its ending point is the later of the original ten-year term or ten years after the last renewal.
Cancellation is different. Following a public hearing under Government Code Section 50285, the City may cancel for a breach or if the property deteriorates until it no longer meets the required standards. The cancellation fee is one eighth of the property’s full value at cancellation, as determined by the County Assessor without considering the contract’s restrictions. The fee is paid to the State Controller. Appeals go to the Architectural and Preservation Commission under Claremont Municipal Code Chapter 16.321.
How is the potential tax benefit estimated?
The County Assessor estimates a Mills Act value from the property’s expected income and a capitalization rate with four components.
Those components are a Federal Home Loan Bank mortgage interest rate, a historic property risk factor, the reciprocal of the structure’s remaining life, and the property tax rate multiplied by the assessment ratio.
Claremont’s staff worksheet excludes special assessment district fees. The staff sheet is an estimate for reference only.
The City does not make a payment to the owner. The potential benefit comes from the effect on assessed value, and property taxes are based on that value without special assessments. Because the sources do not explain how the Assessor treats a sale, a buyer should ask the County Assessor directly.
What should buyers and sellers review?
Buyers and sellers should review the recorded agreement, its exhibits and the compliance history before closing.
A buyer should request:
- The recorded contract and any later notices
- Exhibit B, identifying character-defining elements
- Exhibit C, showing the improvement schedule
- Annual letters, pictures and receipts
- Records of compliance reviews and inspections
- Information about prior or scheduled tours
- Any owner or City notice of nonrenewal
The buyer should determine how much time remains, which improvements are finished, and which obligations are still pending. Planned changes to protected features should be compared with the contract’s prior-review requirements. Any question about assessed value after the sale belongs with the County Assessor.
A seller should be ready to hand over the contract, Exhibits B and C, annual submissions and related City records. If nonrenewal has been considered or started, the seller should provide the notice and explain its timing through the documents rather than assuming the contract ends at the sale.
The Riverside Mills Act guide and La Mesa Mills Act guide cover their own city-specific agreements and procedures.
The short version
A recorded Claremont Mills Act contract can bind a buyer who succeeds the current owner.
For the 2026 draft, that means preserving listed features, completing scheduled improvements, reporting each year, paying the annual review fee, permitting scheduled inspections and coordinating limited public access. The agreement renews annually unless timely nonrenewal notice is given. Cancellation for breach or serious deterioration carries a fee based on one eighth of full value.
The tax result is not guaranteed, and the treatment of a sale should be confirmed with the County Assessor. Start with the recorded agreement and Exhibits B and C, then match those documents against the property’s compliance records.
For another practical next step, use the home value tool.
Common questions
Does a Claremont Mills Act contract transfer to a buyer?
The draft contract says it binds successors and assigns. A buyer would receive the same rights and obligations as the owner who signed it.
How long does the draft Mills Act contract last?
Its term is ten years. One year is automatically added on each anniversary unless the owner or City gives timely notice of nonrenewal.
What records does the owner submit each year?
The draft requires an annual letter describing completed improvements, with pictures and receipts, plus an annual compliance review fee.
Does the City pay the property owner?
No. The draft says the owner receives no payment from the City. The potential benefit comes through the property's assessed value.
