Lot Coverage and Floor Area Ratio Standards for the RR-20 Rural Residential District
In the Concord Rural Residential (RR-20) zoning district, the maximum permitted lot coverage for single-family residential properties is 20 percent. While the Concord Development Code establishes floor area ratios (FAR) for various commercial and industrial districts, the Rural Residential (RR) districts utilize lot area, width, depth, and lot coverage standards rather than FAR to regulate building intensity.
Lot Coverage Standards in the RR-20 District
The Concord Development Code regulates building intensity in the Rural Residential (RR-20) district through maximum lot coverage percentages. Lot coverage refers to the portion of a lot that is covered by structures, including principal and accessory buildings, garages, carports, and roofed porches, but excluding unenclosed and unroofed decks, landings, or balconies [Section 18.15.030, Section 18.20.030].
For single-family residential properties within the RR-20 district, the maximum lot coverage is 20 percent [Section 18.30.030].
| Standard | RR-20 Requirement |
|---|---|
| Lot Coverage (percent) maximum | 20 percent |
For nonresidential uses within the RR-20 district, lot coverage is established in compliance with the requirements specified by the applicable permit. If a permit is not required, or if the permit does not regulate this feature, the regulations of the abutting district apply to each adjacent portion of the property [Section 18.30.030].
Floor Area Ratio (FAR) Applicability
The Concord Development Code utilizes Floor Area Ratio (FAR) as a regulatory tool primarily for office, commercial, downtown, and industrial districts to limit the maximum floor area allowed on a site. According to the zoning district tables provided in the Concord Development Code, the Rural Residential (RR) districts, including the RR-20 district, are categorized under "Residential Districts" and do not have an assigned FAR in the development standards tables [Section 18.15.020, Table 18.15.020].
Consequently, building intensity for single-family residential development in the RR-20 district is managed through lot coverage, density, and height limitations rather than an FAR metric [Section 18.30.030].
