Pursuant to Section 5.148.030 of the San Mateo Code of Ordinances, commercial cannabis cultivation is permitted in the unincorporated areas county by entities or persons who have obtained valid licenses to conduct cannabis cultivation. However, the provisions in that section of the code of ordinances do not provide any immunity or protection for any person from federal or state laws or prosecution under any applicable federal or state laws.
Although California voters approved medicinal cannabis use through Proposition 215 and recreational cannabis use through Proposition 64, California law permits cities and counties to restrict cannabis activities within their jurisdictions as they deem fit.
According to Section 5.148.040 of the San Mateo Code of Ordinances, the following persons may conduct non-commercial cannabis cultivation:
According to Section 5.148.050 of the San Mateo Code of Ordinances, only licenses for mixed-light nursery cultivation and mixed-light cultivation of cannabis are issued in the county. That is, cannabis cultivation license applicants can only obtain the following licenses in San Mateo County:
These licenses are only issued for:
Other than the stated exemptions, San Mateo County does not permit the commercial outdoor and indoor cultivation of cannabis either for medical or non-medical purposes in the county's unincorporated areas. Additionally, no personal non-medical outdoor cultivation of cannabis is allowed in the unincorporated areas of San Mateo County.
According to the San Mateo Planning and Building Department, the Department will not limit the total number of licenses that an owner may hold at any point, as long as the licensee's total approved canopy, as indicated on the licenses, is under 66,000 square feet on a single parcel or across several parcels. The Department permits licensees to locate multiple cannabis cultivation licenses on the same parcel, provided each cultivation premises has a unique entrance and immovable physical barriers separating the uniquely licensed premises. Per county law, licensees are not allowed to commingle cannabis from other premises.
All structures connected with cultivation must be situated back a minimum of 300 feet from adjacent residential and commercial structures. This setback applies only to residential and commercial buildings that exist at the moment a license is initially granted for the subject property unless the subject property is without a valid license for 18 months or longer after the first license issuance.
In the latter situation, residential and commercial buildings added to neighboring properties are presumed to have existed at the time the license was initially granted, and the 300-foot setback requirement applies to such structures. The 300-foot buffer does not apply to residential or commercial buildings located on the same property as the cannabis cultivation site.
Per Section 5.148.160 of the San Mateo Code of Ordinance, all cannabis cultivation premises must have a minimum setback of 500 feet from any school offering education to K-12 grades, youth centers or playgrounds defined under Section 11353.1 of the California Health and Safety Code, licensed daycare center, and alcohol or drug treatment facility defined under Section 11834.02 of the California Health and Safety Code.
Also, all premises other than those operating only under a Type 4 nursery license must be setback at least 600 feet from any properties designated for residential use by the San Mateo County General Plan or any local general plan.
In San Mateo County, cannabis cultivators must not displace any non-cannabis commercial production with their cultivation activities. However, a licensee may offset a proposed cultivation site by relocating existing agricultural production to a separate area of the property where the cultivation premises are located on a 1:1 ratio. In such instances, a relocation must not conflict with any applicable regulation or policy. If the proposed cultivation site is located on a parcel subject to the Land Conservation Act contract, the licensee must comply with the Uniform Rules and Procedures of the Land Use Conservation Act prior to conducting cannabis cultivation activities.
Pursuant to Section 5.148.050 of the San Mateo Code of Ordinances, cannabis manufacturing is illegal in unincorporated parts of the county. However, some cities in the county have approved cannabis manufacturing within their borders. For instance, Brisbane city and South San Francisco city permit cannabis manufacturing within their borders.
According to Section 5.148.050 of the San Mateo Code of Ordinance, cannabis retail activities are prohibited in unincorporated parts of the county. Still, with Proposition 64 permitting cities to set their cannabis activity rules, many cities allow cannabis dispensaries to operate in their jurisdictions. Burlingame City, Redwood City, Brisbane City, and South San Francisco are all San Mateo County cities permitting cannabis retail.
Per Section 5.148.050 of the San Mateo code of ordinance, delivery of cannabis to consumers is lawful in the county. In accordance with the provisions of this section, no physical locations for delivery services are permitted within the unincorporated parts of the county.
However, Burlingame City Council has approved non-storefront cannabis delivery businesses to operate in certain parts of the city's industrial districts. While Burlingame City prohibits cannabis businesses from selling cannabis on-site, these businesses are also not permitted to display any exterior signs on their premises or delivery cars, as well as publicizing their business location.
Burlingame City requires all prospective cannabis delivery businesses to obtain conditional use permits from the county Planning Commission to operate. Brisbane City permits cannabis delivery establishments, Redwood City permits delivery and up to six storefront retail businesses, while South San Francisco also permits delivery, depending on the zoning district.
