Royal Oak, MI Cannabis Regulations: Buffer Zones (2026)

Section 435-5A(5), part of the 2020 recreational marihuana establishment article (Ord. No. 2020-06, amended 2023 and 2024), sets two hard distances rather than a single blanket buffer. First, no marihuana establishment of any kind, retailer, microbusiness, grower, processor, secure transporter, or designated consumption establishment, may sit within a 1,000-foot radius of any school. Second, retailers and microbusinesses specifically must also stay 1,000 feet from any other existing retailer or microbusiness, preventing clusters of storefront cannabis shops. Both radii are measured from the outermost boundaries of the lot or parcel on which the establishment sits or would sit, not from a building's front door, so an oversized parcel can push the qualifying distance further than expected.

The spacing requirement becomes legally effective the moment a municipal license, even a conditional one, is issued, locking in the buffer against later-arriving competitors. The City Commission holds the only lever to shrink these distances: under §435-5A(5)(c), it may grant a deviation, including an outright reduction, if the applicant demonstrates features adequate to protect public health, safety, and general welfare from excessive noise, traffic, and odors, and to minimize harm to the neighborhood's character. Notably, the spacing rule names only schools and other cannabis establishments as protected uses; it does not set a separate distance from parks, playgrounds, or houses of worship, so any additional buffer around those uses would come from the City's zoning map rather than this chapter.
