Cannabis Regulations in Wilmington, DE

If you live in Wilmington or are thinking about moving there, cannabis regulations are one of those things you probably won't think about until they affect you directly. Wilmington has 2 specific rules on the books covering different aspects of cannabis regulations, and some of them might surprise you.

Dispensary Zoning

Retail marijuana stores need a 300-foot buffer from residential zoning districts and K-12 schools, and are allowed by right only in the city's C-5, M-1, M-2, and waterfront manufacturing zoning districts.

Key details: Buffer distance: 300 feet from homes, K-12 schools. Governing section: Wilmington City Code § 48-481. Permitted zoning districts: C-5, M-1, M-2, W-1 through W-4. Adopted: Ord. No. 25-013(sub 1), May 1, 2025.

Siting within the 300-foot buffer of a residential district or a K-12 school violates § 48-481; operating in a zoning district that doesn't explicitly list the use violates § 48-7, both enforced through the zoning administrator and code enforcement.
