The capital stack on a typical Lancaster 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.
Lancaster watch: Antelope Valley.
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.
