SB 1211 for 16-unit apartment in Hayward
In Hayward, a 16-unit 16-unit apartment just became one of the highest-yield SB 1211 typologies — 12 new homes, ministerially approved. At Hayward's median rent of $2,500/mo, that's ~$360K in additional gross annual rent.
The Hayward scenario
The capital stack on a typical Hayward 16-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.
Hayward-specific note: Streamlined ADU intake program.
Large multifamily (10+ unit) design playbook
A 16-unit complex is capped at 8 detached ADUs by statute, so the play shifts toward interior conversions: max(1, ⌊units × 25%⌋) = 4 additional units carved from common rooms, oversized lobbies, basement storage, or laundry rooms.
