Jurisdiction: ConcordCode Version: February 10, 2026

The Community Office (CO) district in the City of Concord requires a minimum lot size of 10,000 square feet, a minimum lot width of 100 feet, and a minimum lot depth of 100 feet. Development on lots smaller than the minimum 10,000 square foot requirement may be approved through a use permit process.

Lot Dimensions and Size Requirements

The City of Concord establishes specific minimum lot size and dimension requirements for the Community Office (CO) district to ensure appropriate development scale and compatibility with surrounding land uses. Development applications must adhere to the following standards:

Standard Community Office (CO) District Requirement
Minimum Lot Size 10,000 square feet*
Minimum Lot Width 100 feet
Minimum Lot Depth 100 feet

*Note: Smaller lots may be approved with a use permit [Section 18.40.030].

Applicability and Exceptions

The Community Office (CO) district is intended for a mix of small-scale single and multiple-tenant businesses, professional offices, and medical offices in low-rise buildings compatible with adjacent residential areas [Section 18.40.010].

While the minimum lot size is 10,000 square feet, the City of Concord provides a mechanism for flexibility. If a proposed project in the Community Office (CO) district does not meet the specified minimum lot size, a use permit may be approved to allow for smaller lots [Section 18.40.030]. Additionally, reduced dimensions for lot width and depth may be allowed subject to use permit approval if specific project site conditions justify the deviation [Section 18.40.030].
