A real Pasadena buyer story from Team Betty Wong Real Estate
Historic homes in Pasadena are not just beautiful — they can also come with meaningful financial benefits. One of the most important programs buyers should understand is the Mills Act, a California historic preservation program that may reduce property taxes for qualified historic properties.
Recently, Team Betty Wang Real Estate helped our dear client Joan purchase a beautiful Spanish Revival historic home in Pasadena. The property is on the historic register and protected under the Mills Act.
This was not a simple transaction. The home received multiple offers, and we had to compete in a bidding process. With the right strategy, we helped Joan’s offer stand out and she became the new owner of this hidden historic gem.
This transaction was especially meaningful because Joan is also Betty's neighbor in Altadena. After losing her home in the Eaton Fire in January 2025, she was not just looking for another house. She was looking for a new beginning.
In addition to the home’s historic beauty and architectural details, the Mills Act protection may help her save over $10,000 per year in property taxes.
That experience reminded me how little many buyers know about Mills Act homes — and how quickly people become nervous when they hear the words “historic property.”
The truth is simple: a Mills Act home is not something to fear. It is something to understand.
What Is the Mills Act?
The Mills Act is a California historic preservation program that allows local governments to enter into contracts with owners of qualified historic properties. In exchange for agreeing to preserve, maintain, and when appropriate, rehabilitate the historic character of the property, the owner may receive property tax relief. The California Office of Historic Preservation describes the Mills Act as a key financial incentive for the restoration and preservation of qualified historic buildings.
In Pasadena, the program is administered through the City of Pasadena’s Historic Property Contract Program. Pasadena allows qualifying privately owned historic properties to enter into contracts when owners agree to restore, rehabilitate, and/or maintain the property according to preservation standards.
In simple terms:
A Mills Act homeowner agrees to preserve the historic character of the property, and in return, the property may qualify for reduced property taxes.
Do Mills Act Homes in Pasadena Have Lower Property Taxes?
Mills Act homes may have lower property taxes, but the savings are not guaranteed.
According to Pasadena’s Mills Act Program Guidelines, there is no guaranteed tax savings under a Historic Property Contract, and the amount is not known until after the contract is signed and the property is assessed. However, Pasadena also states that among owners who do realize tax savings, the average benefit has been about a 51% reduction in property taxes, though the amount can vary widely.
For Joan’s Pasadena historic home, the expected benefit was especially meaningful — over $10,000 per year in property tax savings.
That can make a major difference for a buyer who already loves the home and is willing to care for it properly.
Why Are Buyers Hesitant to Buy Mills Act Homes?
Many buyers hesitate because they are afraid a historic home will come with too many restrictions.
Common concerns include:
“Can I renovate a Mills Act home?”
“Will the city control everything I do?”
“Will repairs be more expensive?”
“Can I change the interior?”
“Is a Mills Act property harder to resell?”
“Are the tax savings worth the responsibility?”
These are valid questions. A Mills Act home does come with responsibilities. But that does not mean the home is impossible to update or difficult to live in.
The key is understanding the contract, the protected historic features, and the city’s review process before purchasing the property.
Can You Renovate a Mills Act Home?
Yes, you may be able to renovate a Mills Act home, but changes should respect the property’s historic character.
The Mills Act does not mean a home must be frozen in time. It means the owner agrees to preserve the historic and architectural features that make the property significant.
Depending on the property and the city’s rules, some changes may require review or approval, especially exterior changes or work involving character-defining features.
Before buying a Mills Act home in Pasadena, buyers should review:
The existing Mills Act contract
The property’s historic designation
Any required preservation or rehabilitation work
Which architectural features are protected
What improvements may need city review
Whether the home’s condition fits the buyer’s budget and lifestyle
What Are the Benefits of Buying a Mills Act Home?
The biggest benefit of a Mills Act home is the combination of historic character and potential tax savings.
For the right buyer, a Mills Act home may offer:
Potential property tax savings
Unique architecture and craftsmanship
Historic and cultural value
A home with character that cannot easily be recreated
Long-term preservation of the property’s beauty
A chance to own part of Pasadena’s architectural history
Pasadena is known for its historic neighborhoods and architectural styles, including Spanish Revival, Craftsman, Tudor, Colonial Revival, and Mid-Century homes. A Mills Act property can be especially attractive for buyers who value design, history, and long-term stewardship.
What Are the Cons of Buying a Mills Act Home?
A Mills Act home is not right for every buyer.
Potential drawbacks may include:
More responsibility for maintenance and preservation
Possible limitations on certain exterior changes
Need for city review before some improvements
Possible use of historically appropriate materials
Specialized contractors or higher repair costs
Tax savings that vary and are not guaranteed
A preservation contract that transfers with the property
The Mills Act should not be treated as only a tax discount. It is a preservation agreement.
That is why buyers should complete careful due diligence before removing contingencies or closing escrow.
Who Is a Good Buyer for a Mills Act Home?
A Mills Act home may be a good fit for a buyer who:
Loves historic architecture
Appreciates original details
Wants a home with character and story
Is willing to maintain the property thoughtfully
Understands that preservation may require planning
Values potential tax savings
Is comfortable reviewing city requirements before making changes
A Mills Act home may not be the best fit for a buyer who wants to heavily alter the property, remove historic features, or treat the home like a blank canvas.
Can Your Own Home Qualify for the Mills Act?
Possibly.
Not every older home qualifies for the Mills Act. A property usually needs to have historic, architectural, or cultural significance and must meet the requirements of the local city or county. Since Mills Act programs are administered locally, the rules, application process, deadlines, and contract requirements vary by jurisdiction.
If you own a character home in Pasadena, Altadena, South Pasadena, San Marino, or another historic neighborhood, it may be worth exploring whether your property could be a candidate for historic designation or Mills Act protection.
This may be especially valuable if you already want to preserve the home’s original design and use potential tax savings to help offset long-term maintenance costs.
Behind the Scenes: Helping Joan Win in a Multiple-Offer Situation
This Pasadena historic home was a true hidden gem. It had beautiful Spanish Revival architecture, timeless details, and Mills Act protection. Naturally, we were not the only ones who saw its value.
The property attracted multiple offers.
In a competitive bidding situation, the strongest offer is not always just about price. Terms, timing, communication, clarity, and strategy all matter.
For Joan, this home represented more than a purchase. After losing her Altadena home in the Eaton Fire, she needed a place where she could begin again. We worked carefully to position her offer in a way that was strong, clean, and compelling to the seller.
In the end, Joan stood out among multiple buyers and became the new owner of this historic Pasadena home.
This is the part of real estate that means the most to me. It is never just about the property. It is about the person, the timing, the story, and helping someone move forward.
Final Answer: Is a Mills Act Home Worth Buying?
A Mills Act home can absolutely be worth buying — for the right buyer.
If you love historic architecture, understand the preservation responsibilities, and complete proper due diligence, a Mills Act property may offer a rare combination of beauty, history, character, and potential tax savings.
But it is not a decision to make blindly.
Before buying a Mills Act home, make sure you understand:
The property’s historic status
The Mills Act contract
The potential tax benefit
The maintenance obligations
The renovation limitations
The long-term ownership responsibilities
For Joan, this historic Spanish Revival home became more than a house. It became a new beginning — with soul, story, and significant potential tax savings.
