SB 1211 for 6-unit apartment in Fontana
In Fontana, a 6-unit 6-unit apartment just became one of the highest-yield SB 1211 typologies — 7 new homes, ministerially approved. At Fontana's median rent of $1,900/mo, that's ~$160K in additional gross annual rent.
The Fontana scenario
The capital stack on a typical Fontana 6-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.
Fontana-specific note: Logistics-driven rent growth.
Mid-size multifamily (5–8 unit) design playbook
This is SB 1211's sweet spot. A 6-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.
