Full Breakdown

Under Union City Municipal Code § 5.44.050(E), a cannabis dispensary can't be established on a parcel containing a residence, or within 100 feet of any school, child care facility, park, library, or youth center. The same 100-foot buffers apply to commercial cultivation, manufacturing, testing, and distribution under § 5.44.030(E) and § 5.44.060(C), plus a separate 100-foot buffer from any residential zoning district for cultivation and non-dispensary uses. The City Council may waive a buffer only on proof of an actual physical separation preventing off-site impacts.

Violations & Fines

Locating or operating a cannabis business inside the 100-foot buffer without a Council waiver is grounds for permit denial, suspension, or revocation under Chapter 5.44's permit standards.
