San Ramon's Bishop Ranch, a 585-acre corporate office park, isn't retrofitting its half-empty buildings into apartments. Its owner is tearing them down and rebuilding the land as a neighborhood — a $5 billion, 8,000-home bet that a viral case for copying the model across the Bay Area mostly ignores.

A Reddit post drawn from the San Francisco Chronicle put San Ramon back in the regional conversation this week, framing the East Bay suburb as a template: with office vacancy high, replace the offices with housing. But the reporting behind the headline is more specific — and more cautionary — than "should other places follow?" implies. The teardown at Bishop Ranch is the work of a single family developer that has spent four decades owning the entire campus, a set of conditions that barely exists in the dense downtowns of San Francisco, Oakland and San Jose, where the same vacancy problem looks nothing alike.

Bishop Ranch has been controlled since the 1970s by Sunset Development Company, now run by third-generation chief executive Alex Mehran Jr. Rather than attempt the piecemeal office-to-residential retrofits that have stalled in San Francisco, Sunset is razing low-rise office buildings and master-planning the sites into streets, blocks, parks and homes. The developer's own numbers, published on the Bishop Ranch website, describe a $5 billion transformation that will add roughly 8,000 homes across the 585-acre campus over the next decade.

That pipeline is no longer theoretical. According to The Registry, a Northern California real estate trade outlet, Sunset in July tapped homebuilder Lennar to construct a 255-home community called Canopy on a 27-acre office site, with construction slated to begin in 2027. In February, the San Ramon Planning Commission approved The Orchards, a 687-unit development with 21% affordable housing on the former Chevron headquarters site. AvalonBay paid $30.5 million in late 2025 for a Bishop Ranch parcel where it is building 456 apartments, and the city approved 200 affordable units on land Sunset donated to Eden Housing. KB Home, The Registry reported, paid $57.8 million for a 276,000-square-foot office building it intends to demolish for roughly 190 townhomes and single-family homes.

The teardown logic is exactly what makes suburban office parks different from downtown towers. Bishop Ranch's buildings are short and ringed by surface parking, so bulldozing them and replanning whole blocks is cheaper and simpler than gutting a high-rise floor by floor. That is not a small caveat — it is the whole story. A fragmented downtown of individually owned skyscrapers cannot be assembled and razed the way one family's suburban campus can.

The San Ramon numbers behind the debate are stark. The Chronicle reported the city's overall office vacancy at 21.6%, rising to 27.8% for premium Class A space, with stretches of the Interstate 680 corridor above 30%. That tracks the broader collapse: San Francisco's office vacancy sat at 30.1% at midyear, per The Registry — a world away from the 6.9% the region averaged in 2019, before remote work became permanent.

Even the poster child has had to temper its ambitions. Sunset originally floated 10,000 homes at Bishop Ranch before trimming the target, telling trade press that "8,000 units is achievable." The first residents have already arrived — SummerHill Homes sold the initial 53 of a planned 404-home City Village phase in 2024, and Belmont Village opened a 177-unit senior community — but a full build-out that could eventually house 25,000 people is a decade-long proposition dependent on financing, absorption and a housing market that has punished overbuilding before.

So the honest answer to "should other places follow?" is: where they can. Cities sitting on obsolete suburban office parks with cooperative or consolidated ownership — think stretches of Contra Costa, the Tri-Valley and parts of the Peninsula — have a real playbook here. Downtown San Francisco, whose vacancy is worse than San Ramon's, mostly does not. The lesson of Bishop Ranch isn't that empty offices become housing. It's that it takes one owner, a lot of parking lots and a very patient balance sheet.
