SB 1211 for 6-unit apartment in Los Angeles
Own a 6-unit apartment in Los Angeles? SB 1211 lets you stack 7 new units on top of your existing 6: 6 detached + 1 interior. At Los Angeles's median rent of $2,400/mo, that's ~$202K in additional gross annual rent.
The Los Angeles scenario
Picture the typical case: a 6-unit 6-unit apartment on a Los Angeles block built between 1955 and 1975, with surface parking that hasn't been fully utilized in years. SB 1211 turns that parking into 6 detached units plus 1 interior conversion — 7 new doors that didn't exist before 2024.
Los Angeles-specific note: LA has its own ADU bonus program that stacks with SB 1211.
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.
