Zones where a duplex can go
Laguna Hills's code calls this use “Dwelling, 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 |
|---|---|---|
| MLDR Medium Low Density Residential | Allowed | § 9-16.020 |
| MDR Medium Density Residential | Allowed | § 9-18.020 |
| HDR High Density Residential | Allowed | § 9-20.020 |
| PCR Planned Community Residential | Allowed | § 9-21.020 |
| NMU Neighborhood Mixed Use | Allowed — see note Note Reference column: Allowed only in conjunction with a mixed use project | § 9-29.020 |
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: Chapter 9-10 (zoning districts established) is not in the packet except 9-10.060, so any district not listed here (overlay or planned-development districts) is not covered; Each district has its own table; a use with no row in a district table is prohibited there. Overlay zones and specific plans can also change the answer.
