California Business and Professions Code 26054 requires licensed cannabis businesses to sit at least 600 feet from schools, daycares, and youth centers; San Bernardino cities often expand these buffers.
Under state law, cannabis retailers, cultivators, and manufacturers must maintain a 600-foot buffer from any K-12 school, daycare, or youth center providing services to minors, measured per California Business and Professions Code 26054. Unincorporated San Bernardino County prohibits commercial cannabis entirely, but cities permitting operations apply additional buffers from parks, churches, residential zones, and other dispensaries. Adelanto and Hesperia require 1000-foot separation from schools and 600 feet from sensitive uses. Twentynine Palms factors proximity to the Marine Corps Air Ground Combat Center base perimeter.
Operating inside a buffer zone results in license revocation by state regulators and local code enforcement, plus daily fines up to 5000 dollars under municipal cannabis ordinances.
