SB 1211 for 8-unit apartment in Mountain View
In Mountain View, a 8-unit 8-unit apartment just became one of the highest-yield SB 1211 typologies — 10 new homes, ministerially approved. At Mountain View's median rent of $3,100/mo, that's ~$372K in additional gross annual rent.
The Mountain View scenario
The capital stack on a typical Mountain View 8-unit apartment project: existing equity (the lot itself, owned outright in many cases), construction loan against the new ADU appraised value, refi at completion against the stabilized rent roll.
Mountain View-specific note: Tech rent corridor.
Mid-size multifamily (5–8 unit) design playbook
This is SB 1211's sweet spot. A 8-unit existing building maxes out the 8-detached cap (or comes close), so design moves are about packing detached ADUs efficiently around the existing structure and converting underutilized parking.
