Tucson, AZ Cannabis Regulations: Buffer Zones (2026)

a–f, Tucson's Unified Development Code locks in three separate buffer distances that control where a marijuana dispensary can locate at all. g requires a minimum 2,000-foot straight-line gap measured wall-to-wall between the closest exterior or interior suite walls of any two dispensaries, roughly seven city blocks, which effectively caps how densely dispensaries can cluster in any commercial corridor. Subsection (h) adds a 500-foot buffer from any K-12 public, private, or charter school and from licensed childcare centers, measured from the dispensary's closest wall to the school or childcare center's property line, though the code carves out two narrow exceptions: standalone school administrative offices not on a school site, and athletic fields or playgrounds not contiguous with a school site, don't count as a 'school' for this buffer.

Subsection (i) layers on a third 500-foot buffer running from parks specifically listed in Section 6 of the city's Technical Standards Manual, from libraries, and from licensed residential substance-abuse diagnostic, treatment, or rehabilitation facilities. Subsection (j) extends the school buffer to expansions of existing dispensaries, so a dispensary that predates a nearby school still has to clear the 500-foot line before it can expand. PDSD verifies all three buffers during zoning compliance review before issuing a certificate of occupancy; the subsection contains no variance or waiver procedure for an applicant that falls short.
