Phenotopia

Phenotopia is at 443 Dutton Avenue, Suite 11, in Roseland on Santa Rosa's southwest side, in the same complex as The Jelly Donut by the shop's own description. From US-101, take Highway 12 west and leave at the Dutton Avenue exit; the shop gives that route from the Sonoma County Airport, Healdsburg and Petaluma. Parking on site is free, and the shop says it has bike racks.

By train, SMART's Santa Rosa Downtown station at 7 4th Street in Railroad Square is about 0.5 mile away in a straight line, by our calculation from DCC's premises coordinates, with Highway 12 running between the two. The shop's pages suggest a Santa Rosa CityBus transfer from the station but name different routes on different pages, so confirm the route with CityBus before you set out. SPARC, also on this site, is about a mile north on the same road.

The shop's site lists hours of 9 am to 9 pm every day, the full window Santa Rosa City Code allows a cannabis retailer, and its FAQ points to the shop's Google profile for holiday hours. The same FAQ says it does not deliver, so walk in or order online for in-store or curbside pickup.

Bring a government photo ID showing you are 21 or older, or 18 with a valid medical recommendation, since the license covers adult-use and medical sales. The FAQ and homepage say the shop takes debit cards and cash and has an ATM inside; one of its area pages mentions credit cards, so plan on debit or cash. DCC data refreshed 1 Oct 2026 list license C10-0000892-LIC, issued 22 Sep 2021 to Wolf House Properties, Inc, as active through 22 Sep 2027, and the shop prints the number in its site footer.
