California Regulators Propose Updated Cannabis Cultivation Rules and New Sanitation Standards, Opens Public Comment

California’s Department of Cannabis Control has released a new notice detailing proposed modifications to its ongoing rulemaking process focused on cannabis cultivation regulations and the creation of statewide minimum sanitation standards. The updated proposal reflects changes made after earlier public hearings and comment periods and is now open for another round of public input. According to the Department, the latest modifications continue a broader effort to streamline cultivation rules, clarify track-and-trace requirements, and address contamination risks tied to unsanitary handling of cannabis. One of the most significant elements of the proposal is the establishment of uniform sanitation standards that would apply to licensees involved in cultivating, processing, or handling unpackaged cannabis. These standards cover areas such as tool and equipment cleaning, container sanitation, handwashing or glove use, and restrictions on animals in processing and handling areas.

The proposal also refines how the state treats illegal pesticide possession. Under the revised language, cannabis or cannabis products would be considered held under unsanitary conditions if unlawful pesticide products are present on a licensed premises. The Department says this approach better aligns with existing state pesticide law while closing potential loopholes that could allow contaminated cannabis to move through the supply chain before enforcement action occurs. Notably, the rule would allow regulators to treat cannabis held at other premises under the same ownership as unsanitary in certain circumstances.

In addition to sanitation standards, the broader cultivation updates include changes to canopy definitions, clarification of harvest batch tracking and labeling requirements, adjustments to nursery and propagation rules, and the removal or relocation of some previously proposed provisions related to energy reporting and pest management plans.

The Department is accepting written public comments on the modified regulatory text through January 14, 2026. After the comment period closes, the agency will review and respond to feedback before deciding whether to adopt the regulations in final form.
