The Inland Empire angle

Lower rents but cheaper land and faster permits. Logistics-corridor demand has pushed rent growth above the state average. For Rancho Cucamonga owners, the calculus changed overnight: the same lot that once topped out at 2 ADUs can now host 8.

Worked example: an 8-unit building in Rancho Cucamonga

An 8-unit existing multifamily property in Rancho Cucamonga can add up to 10 new homes under SB 1211: 8 detached units (the statutory cap) plus 2 interior conversions. At Rancho Cucamonga's median rent of $2,100/mo, that's roughly $252K in additional gross annual rent on land you already own.

The arithmetic is straightforward: 8 detached + ⌊units × 25%⌋ interior, on lots zoned for the units already there.
