The Orange County angle

Master-planned overlays and HOAs are the friction here, but Civil Code §4751 voids HOA prohibitions on ADUs. The play in Fullerton isn't speculative — it's running the §66323 math against existing owners with surface parking they'd otherwise leave empty.

Worked example: an 8-unit building in Fullerton

An 8-unit existing multifamily property in Fullerton can add up to 10 new homes under SB 1211: 8 detached units (the statutory cap) plus 2 interior conversions. At Fullerton's median rent of $2,500/mo, that's roughly $300K in additional gross annual rent on land you already own.

Where local ordinances conflict with §66313–66323, state law preempts.
