Prince George's County, MD Cannabis Regulations: Buffer Zones (2026)

Section 27-5102(b)(1)(B) of Subtitle 27, the Zoning Ordinance, sets the buffer for an outdoor cannabis grower use. The property boundary must sit at least 300 feet from the RE, RR, RSF-95, RSF-65, and R-PD Zones, from any land owned by the Maryland-National Capital Park and Planning Commission (the agency that manages the County's parks), and from any pre-existing primary or secondary school, licensed childcare center, or registered family childcare home under the Education Article of the Maryland Code. The 300-foot rule applies to outdoor cultivation footprints; the same distance and protected-use list apply separately to Cannabis Micro-Grower operations under Section 27-5102(b)(1)(C).

Outside the AG Zone, all cultivation, processing, and storage tied to a cannabis grower use must occur inside a fully enclosed building, so most growers in commercial or industrial zones never trigger the outdoor buffer at all. In the AG Zone, State-licensed outdoor cultivation is allowed, but the cultivation area itself must be set back at least 100 feet from any street or property line, fenced to State licensing standards, and separated from the fence line by a planted bufferyard. Signage is limited to building-mounted signs, and the Ordinance flatly bars any advertisement for cannabis or cannabis products on the property.

A cannabis grower can never be established as an accessory use to another business or residence; it is permitted only as a standalone principal use reviewed against these standards through DPIE's building permit process.
