Full Breakdown
The City of San Marcos treats cannabis use near children's facilities as a line it will not let residents cross. 3, while children are present at the site. The rule borrows state law's definitions of covered facilities but applies the distance and 'while children are present' trigger as San Marcos's own local standard. The only carve-out is for cannabis use on the grounds of a private residence, and even then only if the use is not detectable by anyone on the school, day care or youth center grounds while children are present.
030(b), the buffer functions as a use restriction layered onto a city with no licensed dispensaries, delivery hubs or lounges to begin with. 030. 050, and each day a violation continues counts as a distinct offense.
Violations & Fines
A knowing or willful violation of the cannabis buffer is a misdemeanor punishable under Section 1.12.010, per Section 5.54.060(a). The City may also sue civilly under Section 5.54.060(b) and 1.12.020, recovering attorneys' fees and costs including witness fees. Because Section 5.54.050 labels every violation a public nuisance, the City can additionally pursue nuisance abatement, and each day the violation continues is charged as a separate offense.
