When a historic home in Old Towne Orange comes with a recorded Mills Act contract, that contract has become one of the hardest things in the city to get any other way. The City of Orange says it is "not presently accepting" new Mills Act applications while the program is under review. The Old Towne Preservation Association reported in January 2026 that the City had not said when intake would resume. So for a buyer who wants the program's tax treatment, the realistic way in for now is to buy a property that already has a contract. That contract comes with a work plan, a reporting history, and obligations the City has started to enforce.
The math of a capped program
A March 2026 Preservation Working Group report, citing County Assessor data, counted 391 active Mills Act contracts in Orange in fiscal 2023-24 and 410 in fiscal 2024-25. The City's own program page uses an older, looser figure, saying "more than 200" properties have received the benefit.
Compare that base with what the City has proposed for new contracts. The Working Draft Mills Act Program Guidelines say that unless the City Council sets a different number by resolution, "no more than eight (8) new Contracts shall be approved in any calendar year." The Director could allow more for properties that need urgent stabilization. The draft would also open applications only from January 1 to April 30 each year and push anything filed later to the next year's cycle. The City's older application form, still posted online, described first-come, first-served intake with no annual cap.
The draft would also change who gets in. Applications would be ranked by how much preservation need they address and whether the owner's planned investment matches the projected tax savings. Work done before a contract is approved generally wouldn't count. Neither would routine maintenance like fence repair or minor plumbing, or interior remodeling unrelated to historic features. A buyer planning to restore a house first and apply afterward would be in the exact situation those rules exclude.
None of this has been adopted. The cap and the intake window are still proposals. But the direction is clear. Hundreds of existing contracts carry forward with their properties, while the route to a new one would be narrow, competitive, and once a year.
What transfers to you at closing
Under the California Government Code, a Mills Act contract is binding on "successors in interest," who take on the same rights and duties as the original owner. Orange says its contracts are recorded against the property and pass to future owners. Owners file annual work reports and update the rehabilitation plan every ten years. State law already requires a City inspection before a new contract and every five years after that. The draft guidelines would make the owner pay for those inspections.
The tax side also changes at the sale. The California Revenue and Taxation Code requires the Assessor to value a Mills Act property by income capitalization: a fair rent, minus eligible expenses, divided by a statutory rate. Comparable sales don't set the value. When a property changes hands, the sale sets a new base-year value. Under Board of Equalization guidance, the Mills Act method still applies, and the enrolled value is the lowest of three: the restricted income value, current market value, or the factored base-year value. A seller who bought decades ago may have a much lower base year than you will, so their tax bill doesn't tell you what yours will be. The City says reductions depend on ownership history and assessed value. It refers owners to the Orange County Assessor's Special Properties Division at (714) 834-2727 for a parcel-specific estimate. That call is worth making before you write an offer. A tax professional should look at the result.
The roughly 40 letters
In August 2025, the City sent letters to Mills Act contract holders. OTPA reported in January 2026 that a second, more targeted round would go to holders considered out of compliance. At first, that meant properties that hadn't paid the annual filing fee or hadn't reported any completed work in roughly five to ten years. OTPA put the number at about 40 properties. The Preservation Working Group report also recommends compliance audits and revisiting fees. Its authors noted they did not have City data on how many holders were actually compliant.
For a buyer, a lapse by the seller becomes your file once you close. The stakes are written into state law. If a local government cancels a contract for breach or for letting the property deteriorate, the owner owes a fee of 12.5% of the property's current fair market value, figured as if the restriction didn't exist. Cancellation goes through a statutory process, and an ordinary sale doesn't trigger it. But it is the reason the compliance file deserves the same attention as the inspection report.
Before removing contingencies on a Mills Act home in Old Towne, ask the seller for:
- The recorded contract, so you know the actual terms and anniversary date.
- The approved work plan, including the items still open and their timelines.
- Copies of past annual reports and proof the annual fee was paid. The City's older application form lists a $100 annual processing fee and notes it may change.
- Any letters from the City, especially from the August 2025 round or later follow-ups.
- Confirmation that recent exterior work went through design review, since unapproved changes can conflict with both the contract and district standards.

The design rules transfer too
Most exterior changes in Orange's historic districts need review. Staff handle many minor projects. Bigger changes go to the Design Review Committee. Whether or not the house has a Mills Act contract, these rules shape what you can do with it:
- Windows and doors: historic ones should be repaired before they're replaced, and vinyl windows are prohibited in the district. Under the September 2024 standards, a replacement window or door has to match the original's size, shape, pane arrangement, and materials.
- Additions: they're expected to stay subordinate to the historic building and generally sit in its rear half. The September 2024 standards prohibit vertical additions on top of historic buildings.
- Finishes: historically unpainted masonry, concrete, or wood can't be painted.
- ADUs: the City's page says ADUs are exempt from referral to the committee, but its submittal requirements still cover them. Additions, infill, and ADUs in a historic district need a historic-resource evaluation by a professional who meets the Secretary of the Interior's qualifications. Converting an accessory structure into an ADU also requires a condition and feasibility assessment.
The review process itself is also changing. In October 2025, the Council voted 5-2 to limit the Design Review Committee to historic properties and send other projects to administrative staff review. Councilmembers Arianna Barrios and Ana Gutierrez voted no, Foothills Sentry reported. The pending Ordinance No. 14-26 would replace the committee with a new Heritage Commission. Under the draft guidelines, that commission would also review Mills Act applications.
The dates that decide the rules
| Date | What happens | Status as of October 4, 2026 |
|---|---|---|
| September 22, 2026 | Council took up Ordinance No. 14-26 and Mills Act Resolution No. 11720 | Ordinance continued 7-0; resolution continued 5-1 with Mayor Slater recused |
| October 13, 2026 | Next Council meeting; the Mills Act resolution is expected to return | Pending |
| November 10, 2026, 6 p.m. | Continued hearing and first reading of Ordinance No. 14-26 at 300 E. Chapman Avenue | Scheduled |
The City Clerk's notice of continuance confirms the November 10 date for the ordinance. If you're in escrow on an Old Towne home this fall, the cap, the intake window, and the commission structure could all be settled while your contingency period is still running.

Quick answers
Can I apply for my own contract after I buy a historic home without one? Not right now. Applications are on hold. If the draft guidelines are adopted as written, you would apply during a January 1 to April 30 window and compete for a limited number of approvals.
Does buying a Mills Act home trigger the 12.5% fee? No. State law sets the fee for cancellation by the local government after a breach or deterioration finding, not for an ordinary sale.
What if I decide I don't want the contract? An owner can file a notice of nonrenewal at least 90 days before the anniversary date. The contract then stays in force for the rest of its term. Board of Equalization guidance phases the value toward the unrestricted value during those remaining years rather than ending the benefit all at once.
