What Is the Mills Act and Does It Apply to a Pasadena Craftsman?

What does the contract actually do?

The agreement is between the property owner and the city. It places preservation commitments on the property while allowing the assessor to consider the restricted-property valuation method. It is an agreement about the property, not a tax exemption simply awarded because a house looks historic. State law requires a contract term of at least 10 years and makes it binding on successors. Government Code section 50281, checked 2026-11-05.

For a buyer, I read the recorded agreement and its preservation plan together: the plan sets the work and timeline, and the contract binds successors. For the details of an ownership change, see how the contract transfers to the next buyer. Pasadena program guidelines, checked 2026-11-05.

A listing description is no substitute for the adopted plan. I compare completed work and remaining projects with the plan’s dates; the contract has a minimum 10-year term.

How can I tell whether the home is eligible?

Start with the designation, not the porch or the listing description. Under state law, a qualified historical property is privately owned, not tax exempt, and meets the statutory listing or historic district criteria. The city’s review determines whether a particular property meets its program requirements. Government Code section 50280.1 and Pasadena guidelines, checked 2026-11-05.

Pasadena points owners to its searchable historic property database and its Map My Neighborhood tool, where the Historic Properties layer can be selected. Its Design & Historic Preservation staff can address questions about a property’s status. When I walk a Craftsman with a buyer, I start with the address in those tools and keep the designation information with the transaction documents. In Bungalow Heaven, for example, the city’s landmark district and the National Register district have different boundaries. Bungalow Heaven conservation plan, checked 2026-11-01. Confirm the property’s status with the city. City of Pasadena historic preservation, checked 2026-11-05. For the search process, see how to find out if a Craftsman is landmarked or in a historic district.

If you have a property in mind, text me.

Designation and a contract are separate matters. A designated home may be eligible to apply without already having a contract. When a listing says a contract exists, I pull the recorded agreement as well. Local program criteria vary, so check the applicable city’s rules for a home in South Pasadena or Sierra Madre. California Office of Historic Preservation, checked 2026-11-05.

What does Pasadena consider in an application?

Pasadena’s guidelines describe the application and selection process, including a proposed preservation plan. Applicants submit the grant deed and the most recent property tax bill. The city does not select properties with unresolved code violations, and work started or completed before a decision does not count toward the proposed work. Pasadena program guidelines, checked 2026-11-05.

A non-contributing property in a historic district has a specific potential path: the contract must restore it to contributing status using pictorial, documentary or physical evidence. The city does not accept conjectural changes as the basis. The single-family cap is $2.0 million in total assessed value. It does not apply to works by Greene & Greene, historic monuments or properties individually listed in the National Register; the city may grant one other exception each year. Homes already rehabilitated or without a need for future rehabilitation are ineligible. Selection is competitive and based on points, with up to 20 new single-family contracts a year. The 2026 application window closed May 29, 2026; no 2027 date was posted as of November 5, 2026. Pasadena guidelines and city program page, checked 2026-11-05.

For help with the application questions, text me.

I put the proposed plan beside the house’s condition and the owner’s intended projects, then look for evidence supporting the restoration and the dates for each item. Eligibility does not guarantee selection; Pasadena’s 2026 window closed May 29.

How does the county calculate the assessed value?

The Los Angeles County Assessor calculates a restricted value using an income capitalization method. In plain English, the calculation looks at fair rent or reasonably expected income, subtracts ordinary and necessary expenses, and applies a statutory capitalization rate. For example, on an owner-occupied single-family home, the statutory capitalization rate includes a 4% historic-property risk component along with interest, property tax and improvement amortization components. The assessor divides income after ordinary and necessary expenses by that combined rate. This is an assessment method even when the owner lives in the house. Revenue and Taxation Code section 439.2, checked 2026-11-05.

I can talk through your questions. Call me at (213) 262-5092.

The income method does not simply replace every other value without comparison. Each year, the Assessor compares the restricted value with current market value and the factored base-year value associated with Proposition 13, then enrolls the lowest of the three. The Los Angeles County Assessor and State Board of Equalization, checked 2026-11-05, describe this comparison.

The lowest comparison is enrolled, but that does not tell a buyer the future bill. Pasadena says the amount is unknown until after the contract is signed, and owners with low existing assessments may not benefit. The Assessor says taxes can rise or fall as market conditions change. Pasadena says owners who bought at market prices within the last 10 years are most likely to benefit, but the actual amount is unknown until after signing. Read the current bill as evidence of the present assessment, not a promise of your future tax cost. Pasadena guidelines, checked 2026-11-05.

How long does the obligation last?

The contract has a minimum 10-year term and renews automatically unless notice of nonrenewal is served; its obligations continue for the remaining term. In Pasadena the contract rolls forward so about 10 years always remain. If anyone serves nonrenewal, the contract and its work plan still run for roughly the next nine to ten years while the tax benefit phases out. For notice, cancellation and valuation after a sale, read how the Mills Act contract transfers to the next buyer. Government Code section 50281, section 50282, Pasadena guidelines, page 5 and Revenue and Taxation Code section 439.3, checked 2026-11-05.

What happens if an owner does not comply?

Preservation is an ongoing obligation. State law calls for an interior and exterior inspection before a new agreement and every five years afterward. Pasadena also requires owners to self-certify annually with documentation, and its plan sets the schedule for agreed work. The city may inspect the home by appointment, and its guidelines describe annual inspections. The contract also allows the city, the County Assessor and state agencies to inspect the interior and exterior by appointment with at least 24 hours’ notice. Government Code section 50281 and Pasadena guidelines, checked 2026-11-05.

If the city finds a breach or deterioration below the required historic standard, state law calls for it to cancel after a noticed public hearing or seek court enforcement. On cancellation, the owner pays a fee of 12.5% of current fair market value as determined by the county assessor as though the restriction did not exist. That is a cancellation fee, not the same thing as giving notice of nonrenewal. Government Code sections 50284–50286, checked 2026-11-05.

For help reviewing the records, text me.

I review inspection records, correspondence and proof of completed work to identify anything still outstanding. Pasadena says documentation of completed work should be provided to the new owner on sale. For the related design questions, see what designation can mean for changes and when exterior changes need city approval. State law calls for an inspection every five years.

What should a buyer request before offering?

Ask for the recorded contract and every attached plan or schedule. The contract is recorded, binds successors and carries the same rights and obligations to the next owner. Compare the plan with the home as it stands and ask for documentation of completed work. Government Code section 50282, section 50281 and Pasadena guidelines, checked 2026-11-05.

Next, request the city’s file: designation information, application materials, inspections, correspondence and any record of nonrenewal or unresolved work. Ask the city to clarify anything that is missing or difficult to reconcile with the seller’s information. The work plan’s dates and scope deserve the same attention as the home’s physical condition.

I can help you organize your questions. Call me at (213) 262-5092.

Finally, review the current property tax bill and ask the Assessor how the property is valued. A seller’s bill is useful context, but it is not a quote for your ownership. The city calculates neither the buyer’s future bill nor an assured savings amount when you tour a house. If you are selling, gathering these documents before listing can help a buyer understand the obligations. For the separate sale question, see whether historic designation makes a Craftsman harder to sell.

I start with the recorded contract, its plan and the current tax bill, then compare the plan’s dates with the work documented in the city file.
