Zones where it is not allowed
What else applies
- State law: SB 9 (Gov. Code § 65852.21) allows two homes on most single-family lots with a ministerial permit, also where this table says no.
- Not covered here: Overlay zone tables (GG overlay S7, PD overlay S8, cannabis overlay S6) are not base zones and are left out. Overlay zones and specific plans can also change the answer.
