Spanish & Historic Architecture Mills Act Homes in San Diego | Dawn Leahy
Exploring the value of San Diego’s Spanish and historic homes — and how the Mills Act offers significant tax savings for homeowners committed to preservation.
San Diego is fortunate to have some of the most beautiful and historically significant homes in California. The city’s neighborhoods are filled with architectural treasures — from Spanish Colonial Revival and Mission Revival to Craftsman bungalows and Prairie-style residences. These properties reflect the story of San Diego’s growth in the early 20th century and remain highly sought after today for their character, craftsmanship, and timeless appeal.
For many of these homes, the conversation goes beyond design. Historic designation and the Mills Act program offer owners an opportunity to preserve architectural heritage while receiving meaningful property tax benefits.
The Allure of Spanish & Historic Homes in San Diego
The Spanish Colonial Revival style became synonymous with Southern California following the 1915 Panama-California Exposition in Balboa Park. White stucco walls, red clay tile roofs, arched doorways, and gracious courtyards define these homes, many of which remain in neighborhoods such as Kensington, Mission Hills, Point Loma, and La Jolla.
But San Diego’s architectural richness extends far beyond Spanish Revival. In areas like University Heights, North Park, Burlingame, and South Park, entire streets are lined with early Craftsman bungalows, Prairie homes, and other period styles. Together, these neighborhoods showcase the artistry and vision of the builders and architects who shaped San Diego a century ago.
What Is the Mills Act?
The Mills Act is a California program that allows local governments to grant property tax relief to owners of qualified historic properties. In San Diego, the program is administered through the Historic Resources Board (HRB).
Once a property receives historic designation and enters into a Mills Act contract, the owner can benefit from significant property tax savings — often between 40% and 60% annually. In exchange, the homeowner agrees to maintain and preserve the property’s historic character.
The program not only makes ownership more financially feasible but also ensures that these irreplaceable architectural treasures remain part of San Diego’s landscape for generations to come.
Benefits for Buyers and Sellers
-
For Buyers: Owning a Mills Act home means combining architectural significance with financial practicality. The tax savings can be substantial, and the pride of owning a home with historic value adds another layer of satisfaction. Buyers should understand the maintenance requirements, but for many, the benefits far outweigh the obligations.
-
For Sellers: Having a home that is already Mills Act-designated can enhance its desirability. Buyers are drawn to the tax savings and the prestige that comes with historic status. A properly documented Mills Act home often stands out in the marketplace.
My Experience Representing Historic Homes
Over the course of my 25-year career, I’ve had the privilege of representing clients both buying and selling historic and architecturally significant properties across San Diego. In many cases, my role extends beyond traditional real estate representation:
-
Conducting chain of title research to uncover past owners and their significance
-
Investigating builders and architects when records are available, adding depth to the story of a home
-
Connecting clients with preservation consultants who guide homeowners through the Historic Resources Board designation process and Mills Act applications
These efforts have been especially meaningful in neighborhoods like Sunset Cliffs and Kensington, where I have represented prominent homes that went on to receive historic designation. Here is a link to just a few examples:
1068 Santa Barbara Street - Sunset Cliffs
4494 Tivoli Street - Sunset Cliffs
Representing these homes and clients requires more than marketing — it requires a respect for their history and an ability to share their story with potential buyers and respecting the seller's preservation. It’s a responsibility I take seriously and one of the most rewarding parts of my work.

Should You Consider Historic Designation?
If you own a Spanish Revival, Craftsman, or other historic home, exploring designation may be worthwhile. The process involves research, documentation, and review by the Historic Resources Board — but it can result in substantial property tax relief and add lasting value to your home.
As a real estate broker who has guided clients through this journey, I can help you evaluate whether your property may qualify, connect you with trusted consultants, and ensure that your home is positioned effectively in the marketplace.
Final Thoughts
Spanish, Craftsman, and other historic homes are more than beautiful properties — they are part of San Diego’s cultural identity. With the Mills Act program, preserving that heritage can also bring meaningful financial benefits.
