Zones where it is not allowed
What else applies
- Only the matrices for non-coastal unincorporated Ventura County (8101-2.1) are used. The row has no entry in the commercial or industrial matrix (8105-5), so a single-family dwelling is not listed there. In RPD see Sec. 8109-1.2.2 (a).
- State law: State law lets most single-family lots add an ADU and a JADU (California ADU law) and a second home or a lot split under SB 9 (Gov. Code § 65852.21).
- Not covered here: Coastal Zone (Chapter 1.1 Zoning (Coastal), S20; zones COS, CA, CR, CRE, CR1, CR2, RB, RBH, CRPD, CC, CM) is excluded from Chapter 1 (8101-2.1) and has its own matrix with different permit types (PDP); not given as cells; Zone names are not stated in the packet; Numbers in parentheses in S4 row names are amendment-history references, not notes; Article 7 and 9 specific regulations are not in the packet. Overlay zones and specific plans can also change the answer.
