The Central Valley angle

Lower-rent markets with the best permit timelines in the state. Margins are tight but volume is achievable. Modesto's SB 1211 opportunity sits in the gap between what zoning historically allowed and what state law now requires cities to permit ministerially.

Worked example: an 8-unit building in Modesto

An 8-unit existing multifamily property in Modesto can add up to 10 new homes under SB 1211: 8 detached units (the statutory cap) plus 2 interior conversions. At Modesto's median rent of $1,500/mo, that's roughly $180K in additional gross annual rent on land you already own.

Cities can't require less than SB 1211 allows; they can permit more. Several already do.
