A buyer touring a 1920s bungalow near the Old Towne Orange Plaza pulls up the property tax history and notices something strange. The bill is a third of what a comparable, non-historic home three streets over pays. Their agent explains the house carries a Mills Act contract, a deal the owner struck with the city years ago to preserve the place in exchange for a lower tax bill. The buyer assumes they can do the same thing once they close. They can't. Not right now. The City of Orange has not been accepting new Mills Act applications since it opened the program up for a budget review, and as of the last public update from the Old Towne Preservation Association in January 2026, there was still no date for when that might change.
That single administrative pause changes the math on every historic home in Orange that already carries a contract. It is the detail most buyers never hear until they are deep enough into a deal to feel the weight of it, and it is the reason this particular category of Old Towne inventory behaves differently than the rest of the market right now.
What the Contract Actually Does
The Mills Act lets a city agree, by recorded contract, to assess a qualifying historic property using an income capitalization method instead of comparable sales. Rather than pricing the home the way the county prices everything else, the assessor estimates what the property could reasonably earn in rent, subtracts costs like insurance and maintenance, and applies a capitalization rate. On an owner-occupied home in a walkable historic district, that formula routinely produces a lower assessed value than a market-based one would, which is why the tax savings can be significant.
The City of Orange created its own Mills Act program in 1998, and more than 200 properties in the city have used it since. Any property that is individually listed or eligible for listing on the National Register, or that contributes to one of the city's designated historic districts, can qualify. That covers all of Old Towne Orange's National Register Historic District plus the Eichler-designed Fairhaven, Fairhills, and Fairmeadow neighborhoods, three midcentury tracts the city also protects under its own historic preservation program.
None of that is unusual. What is unusual, and what most generic explanations of the Mills Act skip entirely, is what happens when the city stops taking new applicants.
The Freeze Nobody Mentions at the Open House
Reporting from the Foothills Sentry in late 2024 tied the slowdown in Orange's Mills Act approvals directly to the city's budget situation, since every dollar in reduced property tax revenue from a Mills Act contract is a dollar the city and other taxing agencies don't collect. That review has stretched well past a single budget cycle. The Old Towne Preservation Association's own January 2026 member update put it plainly:
"As of January 2026, the City has not provided an update on when new Mills Act applications may resume."
That is not a paperwork delay measured in weeks. It is an open-ended pause, and Orange is not the only city working through one. Redwood City, a few hundred miles north, voted in March 2026 to suspend its own program while it studies the same equity and revenue questions, after homeowners there had already saved close to $340,000 in aggregate on a single property under contract. Cities across California are re-examining whether the tradeoff still works for them, and Orange's own review has simply run longer than most residents expected.
For a buyer, this means the path to a Mills Act tax bill is no longer "buy an old house and apply." Right now it is "buy a house that already has the contract, or wait indefinitely." That is the scarcity mechanism driving this whole conversation. The supply of Mills Act homes in Orange is effectively fixed at whatever it was when the freeze began, and it can only shrink from here as individual owners let contracts lapse or fall out of compliance. It cannot grow while the program stays paused.
What a Buyer Actually Inherits
Because the contract is recorded against the property rather than tied to the person who signed it, it survives the sale. The new owner assumes every right and every obligation the moment escrow closes. Here is what that means in practice.
| Obligation | What it requires |
|---|---|
| Contract term | Minimum 10 years, renews automatically each year unless either party files notice |
| City inspection | At least once every five years, per the terms written into Orange's own recorded Mills Act agreements |
| Annual reporting | Owner must report on completed repairs and maintenance |
| Rehabilitation plan | Must be updated once every ten years (Exhibit D of the contract) |
| Cancellation penalty | A fee equal to 12.5% of the property's fair market value under state law, if the city cancels for breach |
That last line is the one worth sitting with before you write an offer on a Mills Act home. If the previous owner let deferred maintenance pile up, or skipped an annual report, the compliance problem does not disappear at closing. It becomes the new owner's problem, on the new owner's timeline, and the city's remedy for an uncured breach is spelled out in the contract language itself: cancellation proceedings, followed by that fair-market-value penalty under the same state statute that created the program.
This is exactly the situation the City of Orange has been actively working through with existing contract holders. According to the Old Towne Preservation Association's January 2026 update, the city sent a letter to Mills Act contract holders in August 2025, and after community concerns about how that letter was worded, city staff worked with the preservation association and the Orange Legacy Alliance on a more targeted follow-up aimed specifically at contract holders currently considered out of compliance. If you are buying a Mills Act home in Orange this year, asking directly whether the seller received one of those letters is a reasonable and specific question, not an intrusive one.
The Conversation Sellers Need to Have Early
Because the contract is recorded, a title search during escrow will surface it regardless of whether anyone mentions it out loud. But recording only tells a buyer the contract exists. It does not tell them whether the seller has kept current on annual reports, whether the last five-year inspection turned up anything, or whether there is an unfinished item sitting on the ten-year rehabilitation plan. Neighboring Anaheim spells this out directly in its own historic preservation FAQ, stating that sellers of Mills Act properties are expected to walk buyers through the contract's requirements and flag any unfinished maintenance items before the sale closes. Orange doesn't publish the same line item, but the underlying logic holds everywhere the state law applies: a buyer who signs escrow paperwork without seeing the actual contract and the maintenance history behind it is agreeing to obligations they haven't read yet.
For sellers, that conversation is also where the value gets protected. A Mills Act home with a clean compliance record and a documented tax history is a different asset than one with an open question mark. Given that the city cannot issue new contracts to replace this one if it lapses, a well-maintained Mills Act property is arguably the scarcer half of Old Towne's inventory right now, and buyers researching the market are increasingly aware of it.
Common Questions
Can I apply for a new Mills Act contract on a home I'm buying in Old Towne Orange? Not at the moment. The city has paused new applications while it reviews the program, and as of the most recent public update in January 2026, no resumption date had been announced. Check current City Council agendas before assuming otherwise, since that is the mechanism the city itself points to for status updates.
Does the Mills Act tax benefit end when the house sells? No. The contract is recorded against the property and transfers automatically to the new owner, along with every reporting and maintenance obligation attached to it.
What happens if the previous owner wasn't in compliance? The new owner inherits the compliance status along with the contract. If the city determines a breach occurred and it isn't cured, cancellation can trigger a penalty equal to 12.5% of the property's fair market value under state law. This is one of the clearest reasons to request the full contract file and recent inspection history before closing, not after.
