House hacking in San Bruno (Tanforan / Bayhill / station area).
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.

The house-hack angle
An SFR plus ADU near BART or Caltrain, or room-by-room to YouTube and SFO commuters; small mixed-use on the Transit Corridors Plan corridors where it pencils.
What breaks it
- Tanforan is entitlement-stage: approvals become final only in Fall 2026
- SFO/FAA airspace and aircraft noise cap height and are a livability caveat on the north and east edges
- Life-science demand cyclicality on the Tanforan office and lab program
