Summary

Antioch's cannabis overlay ordinance sets fixed buffers between cannabis retail and any "sensitive use," a defined term covering K-12 schools, licensed day care and youth centers, and city parks. Table B under Antioch Municipal Code § 9-5.3845(E) sets a 600-foot buffer in the CB 1 and CB 3 overlay districts and 200 feet in CB 2, measured property line to property line.

(E) The separation requirements for the Cannabis Business Overlay Zoning Districts shall be as described in Table B:

TABLE B Overlay District Between Retail Uses From Sensitive Use CB 1 600' 600' CB 2 200' 200' CB 3 600' 600'

(1) Notwithstanding § 9-5.3845(E), the city shall have the discretion to decrease the 600-foot restriction without requiring a variance when significant barriers (such as large roadways, railroad tracks, or similar buffers) exist between the proposed retail cannabis business and the existing use identified in § 9-5.3845(D)(4).

Full Breakdown

3845(E), added by Ord. 203 to include any K-12 school, licensed child day care center, youth center offering recreational or social activities for minors, and any public park owned or operated by the city. 3845(E)(3); the separation between two cannabis retail businesses is measured storefront entrance to storefront entrance instead. CB 2 carves out one exception: residentially designated property does not count as a "sensitive use" there, so a cannabis business can sit closer to housing in that overlay than the definition would otherwise allow.

3845(E)(1) to shrink the 600-foot buffer without a variance where a significant physical barrier, such as a major roadway or railroad tracks, separates the proposed retail site from the sensitive use. These buffers apply on top of the underlying permitting scheme: every cannabis business still needs a City Council use permit, an operating agreement covering security, odor control, and social equity commitments, and City Council approval finding the site will not create excessive demand on police or other services.

Violations & Fines

A cannabis business sited inside the buffer, or operating without the City Council use permit and operating agreement § 9-5.3845(B) requires, is an unauthorized commercial cannabis use and can be shut down; operating any cannabis business outside the conditions in § 9-5.3845(A) violates the citywide general penalty, Antioch Municipal Code § 1-2.01, a misdemeanor unless reduced to an infraction, with each day of continued operation a separate offense.

Frequently Asked Questions

How far must a cannabis business be from a school or park in Antioch?
Antioch Municipal Code § 9-5.3845(E), Table B, requires a 600-foot buffer from any "sensitive use," which the code defines at § 9-5.203 to include K-12 schools and city-owned parks, in the CB 1 and CB 3 overlay districts, and 200 feet in CB 2.
Can the city shrink the cannabis buffer distance?
Yes. Under § 9-5.3845(E)(1), the city can decrease the 600-foot buffer without requiring a variance if a significant barrier, like a large roadway or railroad tracks, separates the proposed cannabis business from the sensitive use.
Does the buffer count nearby homes as a sensitive use?
Only outside CB 2. Section 9-5.3845(E)(2) says that in the CB 2 overlay, residentially designated property is not treated as a sensitive use, so the standard buffer there does not apply to nearby housing.
