Zones where a duplex can go
Fresno'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.
| Zone | Status | Code |
|---|---|---|
| RM-1 Residential Multi-Unit District | Allowed | § 15-1002 |
| RM-2 Residential Multi-Unit District | Allowed | § 15-1002 |
| RM-3 Residential Multi-Unit District | Allowed | § 15-1002 |
| RS-5 Residential Single-Unit 5 | Needs a conditional use permit | § 15-902 |
