Summary

San Marcos Municipal Code Section 5.54.030(h)(6) bars smoking, vaping, ingesting or possessing cannabis in public within 1,000 feet of a school, day care center or youth center whenever children are present there. The buffer sits on top of the city's total ban on commercial cannabis, closing off use near every campus, preschool and youth facility in town, with a narrow carve-out for undetectable use on private residential property.

(6)Within 1,000 feet of a school, day care center or youth center, as those terms are defined under California Health and Safety Code Sections 11362.768 and 11363.3, while children are present at the school, day care center or youth center, except in or upon the grounds of a private residence and only if such use is not detectable by others on the grounds of the school, day care center or youth center while children are present;(7)While driving or operating a motor vehicle, boat, vessel, aircraft, or other vehicle used for transportation; and(8)While riding in the passenger seat or compartment of a motor vehicle, boat, vessel, aircraft, or other vehicle used for transportation.(i)Sale of Cannabis Accessories. No person or entity shall sell or permit to be sold any cannabis accessories, or violate any other local, State or federal law regulating drug paraphernalia, including, but not limited to, California Health and Safety Code Section 11362.3, as that section may be amended from time to time. (Ord. No. 2017-1453, § 2(Exh. A), 11-14-2017; Ord. No. 2023-1535, § 2(Exh. A), 10-10-2023)

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.

Frequently Asked Questions

Does the 1,000-foot cannabis buffer apply if no children are on site?
The ordinance's language ties the restriction to times 'while children are present at the school, day care center or youth center,' so the buffer is keyed to the presence of children rather than operating as a blanket, round-the-clock zone. Officers still enforce it whenever a school, day care or youth center has children on the premises, which for most campuses covers the entire school day.
Can I use cannabis at my own home if it's within 1,000 feet of a school?
Yes, but only if the use happens on the grounds of your private residence and is not detectable by anyone on the school, day care center or youth center grounds while children are present. If neighbors or staff can see, smell or otherwise perceive the use from the protected site, it falls back under the citywide prohibition.
Who enforces the San Marcos cannabis buffer zone?
The City's code enforcement and law enforcement personnel enforce Chapter 5.54, citing violators for a misdemeanor under Section 1.12.010. The City Attorney can also bring a civil action under Section 5.54.060(b) to recover fees and costs, and the City may abate any violation as a public nuisance under Section 5.54.050.
