Silicon Valley Office Demolitions Rise as Developers Pivot to Multifamily

Cities along the Highway 101 corridor in Silicon Valley are experiencing a notable surge in demolition-to-multifamily projects [1.2.4]. Driven by high demand, strong rent appreciation, and state-mandated housing targets, developers are targeting obsolete office properties for residential redevelopment. Firms like Beam Reach are actively pursuing projects aligned with local Housing Elements, such as Sunnyvale’s mandate to add nearly 12,000 new homes by 2031. To facilitate these developments, cities like Sunnyvale and San Mateo have introduced local zoning rules that ease the permitting process along key transit corridors. Additionally, state-level legislation like Senate Bill 79, which went into effect to boost density near transit, has provided developers with powerful tools to bypass local restrictions. This trend underscores how the decline of the suburban office market is directly fueling the expansion of suburban multifamily housing.
