Zones where a duplex can go
Yountville's code calls this use “Duplex”. Each row links to the use table it comes from. A zone marked “see note” has a condition in the code, for example upper floors only or a larger lot.

|---|---|---|
| RS Single-Family Residential | Allowed | Division 2 — Zoning Districts, Allowable Uses, Development and Design Standards and Guidelines |
| RM Mixed Residential | Allowed | Division 2 — Zoning Districts, Allowable Uses, Development and Design Standards and Guidelines |
| RM-2 Mixed Residential-2 | Allowed — see note Note table: Zone RM-2 has no column in Table 17.12-1; its own permitted-use list in Section 17.26.030 names this use. | Division 2 — Zoning Districts, Allowable Uses, Development and Design Standards and Guidelines |
| H Old Town Historic | Allowed | Division 2 — Zoning Districts, Allowable Uses, Development and Design Standards and Guidelines |

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: RM-2 has no column in Table 17.12-1 (only its Section 17.26.030 list); Section 17.172 (emergency shelters) is not in the packet. Overlay zones and specific plans can also change the answer.
