In Fullerton, a 24-unit 24-unit apartment just became one of the highest-yield SB 1211 typologies — 14 new homes, ministerially approved. At Fullerton's median rent of $2,500/mo, that's ~$420K in additional gross annual rent.
The Fullerton scenario
The capital stack on a typical Fullerton 24-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.
Fullerton watch: University demand.
Large multifamily (10+ unit) design playbook
A 24-unit complex is capped at 8 detached ADUs by statute, so the play shifts toward interior conversions: max(1, ⌊units × 25%⌋) = 6 additional units carved from common rooms, oversized lobbies, basement storage, or laundry rooms.
