Corona, CA Cannabis Regulations: Buffer Zones (2026)

070(A) sets a 1,000-foot separation, measured from the retailer's public entrance to the exterior property boundary of the protected use, for storefront retailers and storefront retail microbusinesses from any K-12 public or private school, day care center, public or private park within city limits, or residential zone within city limits, all measured as they existed when the initial permit issued. Subsection (B) applies a 600-foot version of the identical four-use buffer to manufacturers, distributors, testing laboratories, non-storefront retailers and non-storefront retail microbusinesses. Subsection (C) adds a separate 600-foot buffer from youth centers that applies to every commercial cannabis business type, storefront or not.

Subsection (D) addresses how the city measures distance across State Route 91 and Interstate 15: the measurement stops at the freeway and does not cross it, but only if the resulting distance still satisfies the state cannabis law's own 600-foot buffer from schools and day care centers under subsections (A)(1), (A)(2), (B)(1) and (B)(2), meaning the freeway carve-out cannot be used to undercut the state-mandated minimum near schools and day cares specifically. All distances are locked in at the time the initial commercial cannabis permit for that business is issued, so a school or park built later does not retroactively displace an already-permitted operator.
