Zones where a duplex can go

Zones where it is not allowed
What else applies
- Standards for this use: Section 88.42.140 (named in the Specific Use Regulations column; the corridor table names 88.42.110; chapter text not in packet).
- Neighborhood and DU tables list "Duplex" and "Triplex or fourplex" as separate rows; DE/DW/DWL and corridors combine them in one row. SB 9 not restated.
- 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: TOD Specific Plan sub-districts DG, DD, DX, DR, DT, DC: Section 88.24.005 A.6 sends readers to the TOD Specific Plan.; Neighborhood zone codes: the table prints NG1/NG2/NG3 over L/MED/MOD; the zone codes NG1-L etc. are joined by the reviewer (the code text does not print the hyphenated form).. Overlay zones and specific plans can also change the answer.
