California Cannabis Regulatory Compliance Attorney

California operates one of the most demanding cannabis and hemp regulatory regimes in the United States. Operators are subject to overlapping state and local rules administered by the Department of Cannabis Control, the California Department of Food and Agriculture, the California Department of Public Health, and dozens of local licensing authorities. Non-compliance can produce license suspension, civil fines, mandatory recalls, and permanent license revocation — consequences that can erase years of investment. The firm provides proactive, ongoing regulatory compliance counsel to retailers, distributors, cultivators, manufacturers, and testing laboratories across California.

California's Cannabis Regulatory Framework

The state’s consolidated cannabis regulations live in Title 4, Division 19 of the California Code of Regulations, administered by the DCC since the agency’s 2021 consolidation under AB 141. Consolidation simplified the state-level picture; it did not simplify the local one. Each of California’s 482 cities and 58 counties retains independent authority over cannabis activity within its jurisdiction, which means compliance for any multi-location operator is necessarily multi-jurisdictional.

Enforcement has intensified. The DCC’s Unified Cannabis Enforcement Task Force has seized hundreds of millions of dollars of unlicensed cannabis products in recent enforcement cycles. The pace and scale of that activity has produced a secondary effect: licensed operators are facing heightened scrutiny, with enforcement teams increasingly examining licensed premises for secondary violations during operations targeting adjacent unlicensed activity.

Hemp regulation has moved equally fast. CDPH Emergency Regulation DPH-24-005 broadly prohibits intoxicating hemp consumables — including products containing delta-8 THC, delta-10 THC, HHC, and THCA — outside the licensed cannabis system. Hemp retailers must source exclusively from CDPH IHEOA-authorized manufacturers and must produce batch-level certificate of analysis documentation on demand. Failures have produced enforcement actions and padlock orders across the state.

Compliance Across the Supply Chain

Compliance obligations differ materially by license type. Cultivators must satisfy CDFA pre-harvest testing (for hemp) and DCC track-and-trace obligations (for cannabis), plus local agricultural and water-use rules. Manufacturers must comply with DCC packaging, labeling, batch testing, and additive restrictions. Distributors must comply with transport manifests, QA testing, and the restrictions on technology-platform profit-sharing structures. Retailers must comply with age verification, advertising restrictions, and DCC inspection record obligations.

Most compliance failures are not the result of operators ignoring the rules — they are the result of operators not realizing a rule has changed, or not realizing a routine operational decision triggers a regulatory consequence. The firm’s compliance counsel is structured to surface those issues before they become enforcement matters.

What Our Clients Say

IRC § 280E — Status as of May/June 2026

Section 280E of the Internal Revenue Code historically prohibited cannabis businesses from deducting ordinary business expenses, because § 280E applies only to businesses trafficking in Schedule I or II controlled substances. On April 22, 2026, the DOJ issued a final order moving state-licensed medical marijuana to Schedule III, removing qualifying state-licensed medical cannabis businesses from § 280E’s scope. The IRS has confirmed that qualifying businesses may deduct ordinary and necessary business expenses under IRC § 162 for the full 2026 tax year.

Important: Adult-use/recreational cannabis remains Schedule I and remains subject to § 280E until broader rescheduling is completed. Dual-license operators (medical and recreational) will need to apportion expenses between Schedule III and Schedule I activities; IRS guidance on apportionment is pending. Regulatory compliance strategy must account for this bifurcation — licensing structures, reporting obligations, and compliance documentation all interact with a business’s § 280E exposure.

Frequently Asked Questions

Q1. How often do California cannabis regulations change?

Materially, several times a year — through DCC rulemaking, CDPH and CDFA action, legislation, and local ordinance amendments. Ongoing compliance counsel is structured around that pace.

Q2. What should I do if I receive a notice of violation?

Respond on time, respond substantively, and do not respond alone. Most NOVs have a defined response window; missing it produces a default outcome. The firm’s first step is usually to evaluate whether the underlying allegation is well-supported and whether the proposed sanction can be reduced or restructured.

Q3. Can I lose my license over a single violation?

Possible but uncommon. Most license revocations follow a pattern of repeat violations or a single severe violation involving public safety or diversion. Early intervention on minor issues is what keeps that pattern from forming.

Q4. Does compliance counsel mean monthly fees?

Often, yes. Ongoing compliance is most effective when it is continuous rather than episodic. The firm offers monthly retainer arrangements structured to deliver compliance counsel on a continuous basis rather than matter-by-matter.

Q5. Do hemp companies need the same level of compliance counsel?

Increasingly yes. Following the CDPH emergency regulations and the federal hemp definition changes, hemp companies face a compliance environment comparable in complexity to the cannabis side.

The April 22 Rescheduling Order: What We Know, What We Don’t, and What to Watch Before June 29

Shay Aaron Gilmore May 25, 2026

The April 22, 2026 rescheduling order moves state-licensed medical marijuana to Schedule III — but leaves adult-use cannabis in Schedule I, creates contested treaty-compliance mechanisms, and opens a June 27 DEA registration deadline that demands immediate attention from California dual A/M operators. Here is what we know, what remains genuinely uncertain, and what to watch before June 29.

The kinds of compliance issues I see my clients in the cannabis and hemp industries facing include product testing and quality control, employee and labor matters, as well as security and inventory control.

Operating within a system of conflicting federal, state, and local rules, cannabis and hemp companies have their work cut out for them when it comes to compliance. The Law Office of Shay Aaron Gilmore is ideally situated to guide clients through the ever-changing application process and regulatory landscape in California, no matter the local jurisdiction. We provide a variety of services for cannabis and hemp regulatory compliance in California, including the following:

Ownership and Financial Interest Changes Under DCC Rules Changes to ownership or control of a licensed cannabis business trigger some of the most sensitive regulatory reviews in California. Under California Code of Regulations, title 4, section 15003, “owners” include not only persons with 20% or more aggregate ownership, but also individuals who manage, direct, or control the operations of the commercial cannabis business. Section 15004 defines “financial interest holders” broadly to capture many investors, lenders, and profit‑participants who must be disclosed even if they are not owners. Routine events—such as bringing in a new investor, redeeming a member, restructuring profit‑sharing, or granting equity‑based compensation—can therefore create ownership or financial‑interest changes that must be reported to the DCC and, often, to local licensing agencies. The firm works with clients to map proposed transactions against these rules, structure deals to avoid unlicensed transfers, prepare the required ownership and financial‑interest disclosures, and coordinate filings and regulator follow‑up so that control can change hands without interrupting operations or jeopardizing licenses. For a deeper dive on owners and financial interest holders, see the firm’s analysis of sections 15003 and 15004.

Local Permitting: Cannabis Bans, Hemp Moratoriums, and Navigating County-Level Restrictions One of the most consequential compliance issues for both cannabis and hemp businesses is local permitting — and the two industries face different but equally unpredictable local regulatory landscapes. Under Proposition 64, California cities and counties have broad authority to ban or heavily restrict commercial cannabis operations, and many jurisdictions have done exactly that: some prohibit all cannabis activity, others allow only certain license types, and those that do permit cannabis often impose conditional use permit requirements, caps on license numbers, and buffers from schools, parks, and residential zones. Cannabis operators must maintain both state DCC licensure and local authorization simultaneously; losing either one shuts down the business. Industrial hemp faces a different version of the same problem. Although hemp is classified as an agricultural commodity under California and federal law, counties retain authority to impose moratoriums, acreage minimums, zoning restrictions, and conditional use permit requirements on hemp cultivation. Some counties have enacted and then lifted hemp moratoriums as they developed permanent ordinances; others maintain restrictions that effectively prohibit commercial hemp operations in certain areas. Hemp operators must also register separately with the agricultural commissioner in each county where they intend to cultivate, and county-level registration can be refused or revoked. Critically, California law prohibits growing industrial hemp on the same premises as DCC-licensed cannabis cultivation — a restriction that can complicate site selection for companies operating in both industries. The firm advises cannabis and hemp clients on navigating local permitting processes, monitoring ordinance changes, and structuring operations so that local compliance supports rather than undermines their state-level licensing or registration.

Ongoing Compliance: Two Regulatory Tracks, Two Sets of Rules

Cannabis and industrial hemp operators in California answer to different regulators and face fundamentally different ongoing compliance obligations. Cannabis licensees are regulated by the Department of Cannabis Control and must maintain compliance with a dense web of state requirements: real-time seed-to-sale tracking through the state’s Metrc system, with 24-hour reporting deadlines for inventory discrepancies and transfer manifests, three-day windows for tagging plants and recording harvests, and mandatory 30-day inventory reconciliations. Cannabis licensees must also renew annually, submitting updated financial disclosures, premises diagrams, and evidence of continued local approval — and late renewals trigger a 50% penalty fee. Each license type (cultivation, manufacturing, distribution, retail, testing, microbusiness) layers on its own operational rules around security, packaging, labeling, and transportation.

Industrial hemp operators face a parallel but distinct compliance regime administered by the California Department of Food and Agriculture and enforced at the county level by local agricultural commissioners. Hemp registrations are also annual and must be renewed at least 30 days before expiration; any lapse in registration renders existing crops non-compliant and potentially subject to destruction. Instead of Metrc, hemp growers must comply with CDFA sampling and testing protocols: pre-harvest THC sampling is conducted by or coordinated through the county agricultural commissioner, and if a crop tests above the 0.3% delta-9 THC threshold it fails as California industrial hemp and cannot be sold. Hemp growers can also face a five-year registration ban after three negligent THC violations within five years. The firm helps cannabis and hemp operators understand which compliance framework applies to their operations — and where clients hold both DCC licenses and CDFA hemp registrations, ensures that compliance in one system does not inadvertently create problems in the other.

Stay Ahead of Enforcement, Not Behind It

Compliance counsel is materially cheaper when it is preventive. A scoped compliance review identifies the gaps most likely to produce enforcement exposure — before the inspector arrives. Button: Schedule a Consultation
