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.

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.
