Zones where it is not allowed
What else applies
- 'Duets' is a separate row (NP in RE, R1, R2, R4-20; P in R3, R4, OT-M, OT-H, RWF; HO P). 'Triplex, Fourplex' is separate.
- 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: Tables for several zones may exist outside the packet (e.g. R4-20 and OT zones are in S1 only; no table for any overlay); S1 note: for properties with an overlay, use the zoning designation, not the overlay. Overlay zones and specific plans can also change the answer.
