Zones where a single-family home can go
Concord's code calls this use “Single-Family, Detached”. 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.

|---|---|---|
| RR | Allowed | § 18.30.020 |
| RS | Allowed | § 18.30.020 |
| RL | Allowed — see note Note 2: Prohibited in the affirmatively furthering fair housing overlay district. | § 18.30.020 |
| NTS North Todos Santos district | Allowed | § 18.35.020 |
| CO | Allowed | § 18.40.020 |

Zones where it is not allowed
What else applies
- 'Single-Family, Detached - Small Lot Subdivision' is a separate row (UP in RS, RL, RM; UP in CO, CMX; UP in NTS). AFFH overlay (Chapter 18.120) prohibits detached single-family homes on overlay parcels; the overlay is not a base zone.
- 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: Zone names for RR, RS, RL, RM, RH, CO, CMX, NC, SC, RC, DP, DMX, WMX, OBP, IBP, IMX, HI, OS, PR, RLC, WRC, CRP-GF (chapter intros not in the packet); Use definitions (CDC 18.20.020) for Group Housing, Residential Care Facility Large, Elementary Middle Secondary; AFFH overlay (Chapter 18.120, S12) is an overlay, not a base zone, and changes SFH, duplex and multifamily rules on listed parcels; Airport overlay (A), other overlays. Overlay zones and specific plans can also change the answer.
