Zones where a single-family home can go
Westminster's code calls this use “One-family dwellings”. 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 |
|---|---|---|
| R1 | Allowed | § 17.210.010 |
| R2 | Allowed | § 17.210.010 |
| R3 | Allowed | § 17.210.010 |
| R4 | Allowed | § 17.210.010 |
| R5 | Allowed | § 17.210.010 |
What else applies
- Standards for this use: Section 17.400.120 Residential Uses - Single-Family Residential.
- Mixed-use (MU) table has only 'One-family dwelling, new (replacement)' = CUP (S5, Sections 17.610.010 and 17.400.120); a replacement-only row, so not given as a cell.
- 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: Section 17.200.020.B (determination of unlisted uses) is not in the packet. Overlay zones and specific plans can also change the answer.
