Zones where a duplex can go

|---|---|---|
| RC | Allowed | § 17.03.110 |
| RA | Allowed | § 17.03.110 |
| R-2 | Allowed | § 17.03.110 |
| R-1 | Needs a conditional use permit | § 17.03.110 |

RR.
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: names of R, C and I zones (tables give codes only). Overlay zones and specific plans can also change the answer.
