Unincorporated Solano County prohibits all commercial cannabis activity under Ord. 2018-1799. Licensed activity is entirely at city level: Vallejo, Fairfield, Benicia, Suisun City, and Dixon each run their own programs, with STIIIZY operating a four-store footprint across the county. Here's how the cities actually stack.
Every figure below is sourced — see each card. Solano's unincorporated ban means every operator lives or dies by city-level program differences, and state enforcement posture has been aggressive in the county (see the November 2024 DCC raid).
The Department of Cannabis Control announced the seizure of more than $5.2 million in illegal cannabis and firearms in Solano County in November 2024 — a direct signal that unlicensed activity anywhere in the county, not just unincorporated areas, is under active state surveillance. (DCC press release, Nov 2024)
Ord. No. 2018-1799 prohibits all commercial cannabis in unincorporated Solano County — retail and manufacturing. Delivery by state-licensed retailers from outside unincorporated county is allowed under AB 1234. Personal cultivation capped at 6 mature / 12 immature medical and 6 recreational plants under Ord. 2017-1788.
Vallejo, Fairfield, Benicia, Suisun City, and Dixon run active cannabis programs, each with its own ordinance, tax rate, and sensitive-use buffer. Vacaville and Rio Vista have limited activity. The program delta between cities is substantial — picking the wrong one is expensive.
California cannabis excise was cut from 19% back to 15% on Oct 1, 2025 under AB 564 per CDTFA L-992 — the rate holds through June 30, 2028. Stacked on top of each city's local cannabis business tax and standard sales tax, retail margin compression eased across Solano's five cities from the brief July–September 2025 19% peak.
This is the work we do: city-level permit packets for Vallejo, Fairfield, Benicia, Suisun City, and Dixon; DCC state-license coordination; METRC reconciliation for vertically integrated Solano operators like STIIIZY and VTown Farms; city-selection strategic advisory; and 24-hour enforcement defense anywhere in the county — especially post the Nov 2024 $5.2M DCC raid. Most Solano work starts with one question: which city fits your margin model, your product mix, and your capital stack?
Solano County occupies a regulatory middle ground. Unincorporated Solano has a total commercial cannabis ban — Ord. No. 2018-1799 prohibits retail and manufacturing in unincorporated areas, and Ord. 2017-1788 limits activity to personal cultivation (up to 6 mature / 12 immature medical plants; 6 recreational plants indoors). Delivery into unincorporated county by state-licensed retailers based elsewhere is permitted under AB 1234 (Bus. & Prof. Code §26090(e)). But the real action is at the city level: five Solano cities have built distinct cannabis programs, and the county's licensed footprint is entirely inside incorporated limits.
The primary city programs are Vallejo, Fairfield, Benicia, Suisun City, and Dixon. Each city has its own cannabis ordinance, business tax, sensitive-use buffer, and permitted activity set. The state default sensitive-use buffer of 600 feet from schools (Bus. & Prof. Code §26054(b)) applies in each city unless the city's ordinance sets a larger distance. STIIIZY — the MSO brand of Ignite/TBC Ventures — has built the county's most visible retail footprint with stores in Benicia, Fairfield, Suisun City, and "Coastal Vallejo," rolled out across 2021–2024. VTown Farms runs a vertically integrated operation in Vallejo (enjoythefarm.com), and Dixon Wellness Collective is the anchor operator in Dixon (dixonwellnesscollective.com).
City-to-city variance is meaningful. Vallejo expanded its dispensary roster during 2018–2019 and remains the largest licensed-operator city in the county. Fairfield and Suisun City came online with STIIIZY-led rollouts during 2021–2024. Benicia permits a small set of retail storefronts in its industrial and commercial corridors. Dixon is the smallest program, anchored by Dixon Wellness Collective. Vacaville and Rio Vista have limited activity — verify current city ordinance language with each before acting. Local city cannabis business tax rates vary; none are published in a unified county-wide schedule, and we do not cite rates from secondary aggregators — pull them from each city's municipal code directly.
Enforcement in Solano has sharpened materially. The November 2024 DCC seizure of $5.2M in illegal cannabis and firearms in Solano County was among the largest single-county DCC actions that year, and signaled that the state sees Solano as a meaningful illicit-supply node — likely because of its position on the I-80 and I-680 corridors between the Bay Area, Sacramento, and Contra Costa. Licensed Solano operators should expect above-baseline inspection cadence for the next several years, with METRC reconciliation, manifest audits, and tax-compliance review all pointing toward tighter city + state coordination. For operators considering new entry, the decision tree is: unincorporated is a non-starter; which of the five cities aligns with your product mix, cap rate, and tax tolerance?
