Zones where a duplex can go
Laguna Niguel's code calls this use “Two-unit attached dwellings (two units per building)”. 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 |
|---|---|---|
| RP Planned residential | Allowed | § 9-1-32 |
| RA Attached residential | Allowed | § 9-1-32 |
Zones where it is not allowed
