Preliminary plans were published late last week for a potential redevelopment of the Hillsdale indoor mall in San Mateo, San Mateo County. Initial details include the demolition of nearly three-quarters of the shopping center’s facilities, leaving just the North Block untouched as the remaining acres are transformed into housing, retail, and multi-level garages. Sares Regis Group is responsible for the application.
Bohannon Development Company and Northwood Investors own the mall. Bohannon is the original owner and developer of the popular shopping center, which opened in 1954 as an open-air mall. Northwood was brought in as a partner in 2021. In a public statement, the senior manager for Northwood, Brady Thurman, said, “we are excited to bring our mixed-use capabilities to Hillsdale and look forward to a long relationship with the Bohannon family and the community of San Mateo.”

The master vision for the development, as described in the planset, is to establish a walkable mixed-use neighborhood that nurtures community. The plans add that their ambition is that “Hillsdale will reaffirm its role as the heart of the Peninsula.” The programming map and plans show a low-rise retail village and public square built across the existing North Block shops, with high-density offices and retail close to El Camino and housing centralized on the western edge of the lot and on 36th Avenue where there’s a mall-owned surface lot at the moment.
The full buildout of the project will create over two dozen structures to expand the overall commercial capacity, add nearly two million square feet of housing, and increase the parking capacity. The commercial floor area will increase from 1.49 million to 2.06 million, with an unspecified mix of retail and office areas. Total parking capacity will increase significantly, too, from 3,399 to 5,390 stalls.

Building heights will vary across the site, pushing the taller structures close to El Camino Real and the shorter buildings by the western edge of the property, where the mall meets a low-rise residential neighborhood. The tallest structures will both reach 160 feet tall at Parcel E1 and S1, with several three-story multiplex homes set back from Edison Street.
Gehl Studio and HOK are jointly responsible for the design. Preliminary drawings and structure elevations show that the developers are going for a diverse range of facade treatments that fit within the contemporary modern style. Most of the glassy offices will rise over El Camino, and the apartment blocks will be articulated between oversized windows and balconies.

The Hillsdale Mall spans around 44.7 acres in southern San Mateo. The mall is less than half a mile from the Hillsdale Caltrain Station and the transit-adjacent 83-acre Bay Meadows masterplan, the nearly complete mixed-use development led by Wilson Meany.
The estimated cost and timeline for construction have yet to be established, but one can be sure that it will be expensive, and work will not be starting any time soon.

This would be amazing progress. Let’s hope it happens. Reminds me of the Stownestown and Eastmont plans.
Lol. By the time this gets built the world will be 3 degrees warmer…
And, at my age, I’ll probably be dead!
Hmm. Interesting idea. I have been expecting this for a while and wondering when the announcement would happen whenever I cruise by the mall on Caltrain. I grew up going there. It was pretty rad when it was an outdoor mall, but they pretty much wrecked it when they converted it to an indoor mall.
Although I would not describe Hillsdale as a dying mall, this kind of reuse is a good one for the thousands of dead and dying malls across the country. I know urban/suburban infill is way more complex than greenfield development, but this type of development should be prioritized and even incentivized to discourage exurban sprawl in the southern Santa Clara Valley and the San Joaquin Valley.
Yes!! Let’s build in the cities and leave the countryside for everyone to enjoy.
If the plan includes townhomes/condos for sale and not just rental units, I would say this plan is perfect. Hard to nurture community if they residents are just tech workers living in the Bay Area temporarily.
On top of the significant redevelopment of this mall (adding thousands of new residences is nothing but a positive), please don’t overemphasize office for residential. Downtown San Mateo has a massive plot for office and too much commercial that sits empty, with more on the way with the loss of Dragers and others. Pretty sure not all the offices near the train tracks are at full capacity. (Hillsdale Sation)
What needs to be of primary focus is how formidable the crossings of El Camino are. It’s not a safe intersection. That dying furniture store and the empty plots across the street are dead zones inspiring nothing. The Michaels/Jersey Mikes combo is crazy busy, but why is there no entrance from the station to that area??? There is one, but that’s from some brave citizen who cut a hole into the steel fencing. (Thank you, kind soul)
If they can get any traffic calming along El Camino, there is genuine potential to make this area more liveable. Adding almost 2,000 new parking stalls isn’t inspiring any big change, though.
Dump the office component for 100% residential. San Mateo city and county have plenty of places for people to work but not enough places for people to live!
I hope this project includes many new apartments, condominiums, ETC.
I agree with the other comments; if there is an excess of office space, it may be a good idea to consider adding more apartments to the project
It appears that some other BA cities are taking growth and density seriously enough to actually address housing shortages, walkability, and TOD. Bueno.
For suburban San Mateo County, this is a fairly transit friendly location. In the interest of minimizing climate change and congestion and improving livability, it’d be great to see less car parking and more transit orientation at this exciting development.
