SB 1211 for 10-unit apartment in Simi Valley
In Simi Valley, a 10-unit 10-unit apartment just became one of the highest-yield SB 1211 typologies — 10 new homes, ministerially approved. At Simi Valley's median rent of $2,400/mo, that's ~$288K in additional gross annual rent.
The Simi Valley scenario
The capital stack on a typical Simi Valley 10-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.
Simi Valley watch: Suburban Ventura/LA edge.
Large multifamily (10+ unit) design playbook
A 10-unit complex is capped at 8 detached ADUs by statute, so the play shifts toward interior conversions: max(1, ⌊units × 25%⌋) = 2 additional units carved from common rooms, oversized lobbies, basement storage, or laundry rooms.
