Tigard, OR Cannabis Regulations: Buffer Zones (2026)

The buffer rules sit in Tigard Municipal Code § 18.430.050.B, which governs every marijuana facility requiring a state license or registration under § 18.430.020.B. The lead sentence fixes the measuring method: all distances are measured at the closest property lines between the proposed site and the nearest lot containing the specified use or characteristic. A building-to-building measurement does not apply.

Paragraph B.2 sets the school buffer. Marijuana facilities are prohibited within 1,000 feet of a public or private elementary school, secondary school, or career school attended primarily by minors. That distance applies to every facility type in the City of Tigard, retail and non-retail alike.

Paragraph B.3.c adds a 500 foot buffer for Sale-Oriented Retail and Wholesale Sales uses open to the public: no facility within 500 feet of a public library or the Parks and Recreation zone. Paragraph B.3.b separately requires 1,000 feet from another state-licensed retail or wholesale marijuana facility, inside or outside city limits.

Paragraph B.4 covers non-retail uses and Wholesale Sales uses not open to the public. These are prohibited within 500 feet of one or more of three things: a residential zone, the Parks and Recreation zone, or a public library. The park-related buffer is therefore tied to the Parks and Recreation zone, not to every park, and the section prints no separate distance for day care centers or religious facilities.

Purpose language in § 18.430.010 explains the design: preventing diversion of state-licensed marijuana and derivatives to minors, preventing or reducing criminal activity, and minimizing impacts to the city's public safety services by reducing calls for service. A Type I procedure under § 18.710.050 reviews each application. Beaverton, Tualatin, Lake Oswego, King City, Durham and unincorporated Washington County areas such as Bull Mountain and Metzger are separate jurisdictions.
