CANNABIS REAL ESTATE DUE DILIGENCE

Acquiring, financing, or investing in California cannabis real estate requires due diligence that goes well beyond standard commercial property review. Every cannabis real estate transaction must address DCC license status and transferability, local permit and CUP compliance, cannabis-specific title encumbrances, environmental assessment for cultivation and extraction residuals, IRS 280E tax exposure, ADA compliance, and the alignment of the real estate timeline with the DCC’s change-of-ownership review process — considerations that standard commercial real estate attorneys are not equipped to address in an integrated way. The Law Office of Shay Aaron Gilmore guides cultivators, distributors, manufacturers, testing labs, retailers, investors, landowners, and management companies through cannabis property purchases, sales, and financings throughout California, coordinating land use, regulatory, corporate, environmental, employment, and IP review in a single engagement.

DCC License Verification: What to Check Before Closing

DCC license status is the most critical due diligence item in any cannabis real estate or business acquisition transaction. A cannabis property without a transferable, compliant license is worth substantially less than one with a clean license record — and in most cases, a license under active DCC investigation or enforcement is a transaction-stopper. The DCC’s public license search portal (search.cannabis.ca.gov) provides license status and expiration information, but the portal does not display enforcement history, pending disciplinary actions, or conditions of approval. A complete DCC due diligence review requires:

License Status Verification.

Confirm that all licenses associated with the property or business are: (a) current and not expired; (b) in “Active” status, not “Suspended,” “Revoked,” or “Pending Renewal”; (c) not subject to a pending Statement of Issues or Accusation (the DCC’s administrative complaint documents). License status can change between the time a purchase agreement is signed and the time of closing — ongoing monitoring through the DCC portal and the Office of Administrative Hearings docket is standard practice in longer-duration transactions.

Conditions of Approval.

The DCC may issue a license subject to specific conditions of approval that restrict the license in ways not visible on the public portal — limitations on permitted activities, required reporting obligations, or remediation milestones. A DCC Public Records Act request for the license file is the standard mechanism for obtaining conditions of approval prior to closing.

DCC Enforcement and Complaint History.

The DCC’s enforcement database and the Office of Administrative Hearings‘ docket are public records. A thorough review covers: prior DCC citations and fines; resolved and pending Statements of Issues and Accusations; consent agreements; and administrative law judge decisions. A history of DCC enforcement action — even resolved action — affects license transferability, DCC approval timeline for ownership changes, and negotiated deal terms.

Local License and Permit Status.

Most cannabis transactions involve both a DCC state license and a local cannabis operator permit, CUP, or business tax registration. Local permits are issued by cities or counties and are not tracked in the DCC’s system. Each local authority must be contacted separately to confirm: (a) permit current and in good standing; (b) no pending local enforcement action or notice of violation; (c) permit transferable on change of ownership; and (d) all conditions of the local CUP are being satisfied.

CEQA Compliance Documentation.

For acquisitions of properties holding annual DCC licenses, CEQA compliance documentation should be obtained and reviewed. Annual DCC license renewal requires evidence of CEQA clearance — a missing or incomplete CEQA record is a license renewal risk that must be identified and resolved before closing.

Environmental and Title Due Diligence for Cannabis Properties

Cannabis real estate — particularly properties used for cultivation or extraction — carries environmental and title risks not commonly encountered in standard commercial transactions.

Environmental Risks Specific to Cannabis.

Cannabis cultivation and manufacturing operations create environmental conditions that warrant specific investigation:

  • Pesticide and soil contamination: Illicit or semi-compliant cannabis cultivation operations — particularly those converted from unpermitted to licensed status — frequently involved pesticide applications that are not registered for cannabis use under California law, and that may have contaminated soil and groundwater. A Phase II Environmental Site Assessment with targeted sampling for common cannabis pesticides is appropriate for properties with known prior cultivation.
  • Solvent contamination: Cannabis extraction operations using flammable hydrocarbons (butane, propane) or other chemical solvents can leave residual contamination in structures, flooring, and drainage systems. Properties with prior extraction operations should be assessed for solvent residuals.
  • Structural and electrical modifications: Cannabis cultivation requires substantial electrical infrastructure upgrades and HVAC modifications. Unpermitted improvements — common in properties converted from prior illicit or provisional-license use — create building code and title issues that must be identified and remediated.

Title Issues Unique to Cannabis Properties.

Standard title review must be supplemented for cannabis properties to specifically examine:

  • Deed restrictions and CC&Rs prohibiting cannabis, controlled substances, or specific uses that cannabis operations would trigger
  • Lender provisions in deeds of trust — many institutional lenders have included provisions triggered by cannabis use; a cannabis tenant or prior owner may have breached these provisions, affecting the status of the property’s title
  • Federal tax liens associated with prior cannabis business IRS 280E liability
  • Restrictive covenants recorded as conditions of prior CUPs or development agreements that survive ownership changes and bind future owners

ADA Compliance.

Cannabis retail facilities are public accommodations subject to ADA requirements. Properties being acquired for cannabis retail use should be assessed for ADA compliance — accessible parking, entrance, restrooms, and customer service areas — because remediation obligations can be substantial and are not excluded from the scope of an acquisition.

Cannabis Real Estate Financing.

Cannabis real estate financing remains constrained relative to conventional commercial real estate because of federal banking restrictions on cannabis businesses. Available structures include: private lenders and hard-money lenders experienced in cannabis real estate; cannabis-focused real estate investment funds; seller financing (common in cannabis acquisitions); and, for hemp properties, conventional institutional financing. The Law Office of Shay Aaron Gilmore advises on and documents construction loans, acquisition loans, and working capital revolving loans for cannabis properties, navigating the regulatory constraints specific to cannabis real estate financing.

Cannabis vs. Hemp: Real Estate Due Diligence Differences

Hemp real estate due diligence follows a substantially simpler framework than cannabis, reflecting the different regulatory environments governing the two industries:
Factor Cannabis Real Estate Hemp Real Estate
License verification DCC portal + PRA request for enforcement history and conditions CDFA registration and county ag commissioner registration; no public enforcement portal
Local permit verification Local cannabis operator permit, CUP, and business tax registration County ag commissioner registration; no local cannabis permit required
CEQA compliance Required for annual license renewal — must be documented May apply but not a licensing prerequisite in the same way
Environmental (pesticides) Cannabis-specific pesticide contamination risk is high for prior cultivation sites Agricultural pesticide use subject to CDPR permitting; standard Phase I applies
Title — deed restrictions Must specifically check for anti-cannabis and anti-controlled-substance provisions Check for anti-agricultural or land use restrictions; less common issue
Financing Private lenders, cannabis funds, seller financing — institutional lending generally unavailable Conventional institutional financing generally available for hemp properties
ADA compliance Required for retail facilities as public accommodations Not applicable to cultivation and processing sites
DCC change-of-ownership review Required for ≥20% ownership transfers — can take months; must be sequenced with closing Not applicable
IRS 280E exposure Material — prior operator's 280E liability can create federal tax lien risk Not applicable — hemp businesses are not subject to 280E

Representative Matters

  • Conducted pre-closing DCC due diligence for a cannabis retail acquisition in Los Angeles, identifying a pending DCC Statement of Issues against the target license that had not been disclosed by the seller; advised the buyer on re-structuring the transaction to include a resolution contingency and adjusted purchase price holdback tied to DCC enforcement outcome
  • Advised a cannabis real estate investor acquiring three cannabis cultivation properties in the San Joaquin Valley on environmental assessment strategy, coordinating sampling for cannabis-specific pesticide residuals and documenting structural modification permit histories for each property prior to closing
  • Guided a buyer of a hemp cultivation property through title review for Williamson Act restrictions, deed restrictions prohibiting commercial cannabis activity, and CDFA registration transfer documentation — coordinating a 30-day pre-closing timeline to avoid registration lapse during the ownership transition

Frequently Asked Questions

Cannabis acquisition due diligence must cover: DCC license status (current, not suspended or subject to pending disciplinary action); local permit and CUP status; DCC enforcement and complaint history (via Public Records Act request); CEQA compliance documentation; title review for cannabis-specific deed restrictions and lender provisions; environmental assessment for pesticide, solvent, and structural modification issues; IRS 280E tax exposure; and employment compliance including worker classification and pending claims.
The DCC requires advance approval for changes of ownership involving transfers of 20% or more of aggregate ownership under 4 CCR §15024. The process requires a change-of-ownership application, background checks for new owners, and DCC review of the licensed entity’s compliance history — a process that typically takes several months. Most acquisition transactions carefully sequence the real estate closing and DCC license transfer so that the buyer does not take possession until DCC approval is confirmed or the parties have agreed to holdback and condition structures that manage the timing risk.
Cannabis real estate carries risks not common in standard commercial properties: pesticide and soil contamination from prior illicit or semi-compliant cultivation; solvent contamination from extraction operations; and unpermitted structural and electrical modifications. A Phase I Environmental Site Assessment is standard; a Phase II with targeted cannabis pesticide sampling is appropriate for properties with known prior cultivation. Structural modification permit history should be obtained from the local building department.
Cannabis title review must specifically examine: deed restrictions or CC&Rs prohibiting cannabis or controlled substance-related uses; lender provisions in deeds of trust triggered by cannabis operations; federal tax liens from prior operator IRS 280E liability; and restrictive covenants recorded as conditions of prior CUPs or development agreements that survive ownership changes and bind future owners.
Cannabis real estate financing is constrained by federal banking restrictions. Available structures include private lenders experienced in cannabis real estate, cannabis-focused real estate investment funds, and seller financing. For hemp properties, conventional institutional financing is generally available. The Law Office of Shay Aaron Gilmore advises on and documents construction loans, acquisition loans, and working capital revolving loans for cannabis properties.
