The Bay Area angle

High land basis but tech-driven rents make ADU pro-formas pencil quickly — payback windows of 6–9 years are common. The play in Vacaville 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 Vacaville

An 8-unit existing multifamily property in Vacaville can add up to 10 new homes under SB 1211: 8 detached units (the statutory cap) plus 2 interior conversions. At Vacaville's median rent of $2,000/mo, that's roughly $240K in additional gross annual rent on land you already own.

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