A rare dual-rail ZIP with two in-ZIP job engines and a 44-acre TOD megaproject atop BART: durable, non-speculative rental demand at ~$1.27M. **Status check:** Verified 2026-07-16: all claims on track (Tanforan on its EIR timeline, the YouTube/Bayhill expansion approved consistent with plan, the Transit Corridors Plan unchanged). One search caveat carried forward: the Transit Corridors Plan / Measure N query returned only the 2013–2014 framework documents, with no fresh 2026-specific confirmation. ## What's actually happening in 94066 - Entitlement, approvals targeted Fall 2026 The Shops at Tanforan redevelopment: 44 acres atop San Bruno BART; ~1,000 homes, ~711K sq ft life-science/office, ~250K sq ft retail (Alexandria and Strada).
