Antioch, CA Zoning Overlays & Bonuses: Downtown Design Guide (2026)

301(T), covering the area within the Downtown Specific Plan planning boundary that the City Council adopted on February 13, 2018. Any parcel carrying the DSP designation is subject to the land use regulations, development standards, and other policies written into the Downtown Specific Plan itself, and the citywide Zoning Code only fills gaps the Plan does not address. 3309, records the findings behind that decision: the Planning Commission held a noticed hearing on March 15, 2017, the Council held hearings on November 28, 2017 and December 12, 2017, and heard the item again on January 23, 2018 before final adoption on February 13, 2018.

The Council relied on Cal. Gov't Code §§ 65450-65457 (the Specific Plan statute) and found the Downtown Specific Plan consistent with the Antioch General Plan. Because the Plan increases density in Rivertown at a lower rate than the certified 2003 General Plan EIR anticipated, the city processed it as a CEQA Addendum rather than preparing a standalone EIR. Downtown design review does not stop at the Specific Plan: the Cannabis Business Overlay District map carries a CB 2 Downtown Antioch sub-area, defined as the Mixed Use area within the Downtown Specific Plan, which is restricted to storefront retail cannabis uses only, unlike the broader CB 1 overlay elsewhere in the city.

Applicants proposing work inside the DSP boundary should confirm with the Community Development Department which specific chapter of the Downtown Specific Plan (land use, streetscape, or design standards) governs their parcel before submitting for design or building permit review, since the Plan document itself, not the general zoning ordinance, controls first.
