The Camarillo scenario
Picture the typical case: a 4-unit fourplex / 4-unit on a Camarillo block built between 1955 and 1975, with surface parking that hasn't been fully utilized in years. SB 1211 turns that parking into 4 detached units plus 1 interior conversion — 5 new doors that didn't exist before 2024.

Small multifamily (2–4 unit) design playbook
Small multifamily lots are usually constrained on width before they're constrained on count. With a 4-unit existing footprint, the binding constraint becomes side-yard setbacks (4 ft min) and the 18-ft height limit. Two-story stacked-flat ADUs over surface parking are the highest-yield typology.
