The Law Offices of Matthew W. Shapiro, APC in downtown San Diego focuses on cannabis-industry law from the B Street corridor, advising retail dispensaries, cultivation facilities, and manufacturing operations on state and municipal licensing, regulatory compliance, and criminal defense. Conditional-use-permit applications under San Diego Municipal Code Chapter 4, Article 2, Division 15 require site plans and floor layouts prepared to city zoning standards, design work executed by architecture firms like Carrier Johnson + Culture in the Gaslamp Quarter. The principal holds both a J.D. and an MBA from the University of San Diego (class of 2013) and maintains active membership in the National Cannabis Bar Association and the NORML Legal Committee, bringing dual legal-business analysis to license applications and corporate structuring. Criminal-defense representation covers cannabis-related felony and misdemeanor charges, including Health and Safety Code § 11358 cultivation violations, with a documented record of securing dismissals and court-ordered return of seized product to wrongfully prosecuted clients. Cannabis facility build-outs must meet California Building Code Title 24 energy-compliance and ventilation requirements, construction overseen by general contractors like Back's Construction Inc in the downtown market. The most complex engagements involve coordinating Department of Cannabis Control Type 7 volatile-solvent manufacturing licenses with local CUP conditions, CEQA environmental review, and state seed-to-sale tracking integration through the METRC compliance platform.
