Development Standards for High Density Residential (RH) District in Concord
The High Density Residential (RH) zoning district in Concord is intended to accommodate compact, high-density residential development with a permitted density range of 33 to 100 dwelling units per net acre. Within the RH district, lot coverage is limited to 75 percent, and specific building height limits are enforced at 60 feet or 6 stories, unless otherwise permitted.
Density and Intensity Standards
The RH district is designed to implement the High Density Residential (HDR) land use designation of the Concord general plan. The following density and lot area standards apply to developments within the High Density Residential (RH) district:
| Standard | RH District Requirement |
|---|---|
| Density (dwelling units/net acre) | 33 – 100 du/net acre |
| Minimum Lot Area | 5,000 square feet |
| Minimum Lot Width | 50 feet |
| Minimum Lot Depth | 100 feet |
| Maximum Lot Coverage | 75 percent |
| Maximum Building Height | 60 feet (or 6 stories) |
Development Requirements
Development within the RH district must comply with the general development standards established in Division IV of the Concord Development Code [Section 18.30.010].
- Building Height: While the base maximum height is 60 feet or 6 stories, additional height may be approved subject to the issuance of a use permit [Section 18.30.040].
- Lot Coverage: The maximum lot coverage of 75 percent applies to the entire project site. Where an RH site is subdivided into small fee simple parcels (e.g., condominiums), there is no lot coverage limit for the individual units [Section 18.30.040].
- Open Space: Residential projects must provide adequate open space and recreational facilities as prescribed in Chapter 18.150 of the Concord Development Code [Section 18.30.040].

| Modified Lot Area | 4,000 square feet |
| Modified Lot Width | 40 feet |
