Permitted Zoning Districts for Single-Family Homes in Concord
Single-family detached and attached dwellings are permitted in various residential and mixed-use districts within the City of Concord, provided they comply with specific development standards and permit requirements. Depending on the zoning district, these uses may be established through a Zoning Clearance (ZC) or a Use Permit (UP) process, and they must adhere to defined lot size, width, depth, and coverage regulations.
Residential Districts Permitting Single-Family Dwellings
The Concord Development Code classifies single-family dwellings into "Detached" and "Attached" types. Residential districts, including Rural Residential (RR), Single-Family Residential (RS), and Residential Low Density (RL), primarily accommodate these uses.
Allowed Uses and Permit Requirements
Table 18.30.020 outlines the permit requirements for single-family residential uses in the residential districts:
| Land Use Classification | RR | RS | RL | RM | RH |
|---|---|---|---|---|---|
| Single-Family, Detached | ZC | ZC | ZC | — | — |
| Single-Family, Detached – Small Lot Subdivision | — | UP | UP | UP | — |
| Single-Family, Attached | — | UP | ZC | ZC | ZC |
Note: ZC = Zoning Clearance; UP = Use Permit; — = Use Not Allowed [Section 18.30.020].
Development Standards for RR and RS Districts
The RR and RS districts have specific minimum lot area, width, and depth standards based on the district's numerical designator.
| Standards | RR-20 | RR-40 | RR-15 | RS-6 | RS-7 | RS-7.5 | RS-8 | RS-10 | RS-12 |
|---|---|---|---|---|---|---|---|---|---|
| Lot Area (min. sq. ft.) | 20,000 | 40,000 | 15,000 | 6,000 | 7,000 | 7,500 | 8,000 | 10,000 | 12,000 |
| Lot Width (min. ft.) | 100 | 150 | 100 | 60 | 70 | 75 | 80 | 100 | 100 |
| Lot Depth (min. ft.) | 100 | 100 | 85 | 85 | 85 | 85 | 85 | 85 | 85 |

Other Districts Permitting Single-Family Dwellings
Single-family residential uses are also permitted in several other districts, including the North Todos Santos (NTS) district and various office, commercial, and mixed-use districts.
North Todos Santos (NTS) District
In the NTS district, single-family detached dwellings are permitted with a Zoning Clearance (ZC), while single-family detached small lot subdivisions require a Use Permit (UP). Single-family attached dwellings require a Zoning Clearance (ZC) [Section 18.35.020].
Office, Commercial, and Mixed-Use Districts
In districts such as CO, CMX, NC, RC, and SC, single-family dwellings may be permitted subject to the specific land use tables for those districts. For example, in the Community Office (CO) and Commercial Mixed-Use (CMX) districts, single-family attached units are permitted as indicated in the land use tables [Section 18.40.020].
Small Lot and Medium Density Standards
For developments on lots smaller than 6,000 square feet, the City of Concord applies specific standards to ensure high-quality design and neighborhood compatibility [Section 18.155.010]. These projects require a Planned Development Use Permit (PDUP) [Section 18.155.030]. Dimensional standards for these small lots are determined by the specific lot area, ranging from 1,440 to 5,999 square feet [Section 18.155.040(B)].
