Summary
Hercules Municipal Code Section 4-18.03(f)(3) makes it unlawful to smoke marijuana within 1,000 feet of any school, day care center, or youth center. The buffer does not apply on the grounds of a private residence, and it excuses smoking otherwise allowed under Business and Professions Code Section 26200, but only if no one at the school or center can detect it.
(3) Smoke marijuana or marijuana products within one thousand (1,000) feet of a school, day care center, or youth center, except in or upon the grounds of a private residence or in accordance with Business and Professions Code Section 26200 or Chapter 3.5 of Division 8 and only if such smoking is not detectable by others on the grounds of such a school, day care center, or youth center.

Full Breakdown
3. The buffer applies to smoking marijuana or marijuana products anywhere within that radius, not just on the institution's grounds, so a resident smoking on a public sidewalk or in a parked car within 1,000 feet of a qualifying facility is in violation even without setting foot on school property. 5 of Division 8 of the Business and Professions Code would otherwise allow the conduct, but only if the smoking cannot be detected by anyone on the grounds of the school, day care, or youth center.
In practice, that second condition means even a residence-based exemption inside the buffer still fails if smoke or odor reaches the protected site. The buffer sits alongside, not instead of, the separate flat ban on smoking in any public place under subsection (f)(1); a single location can trip both provisions at once. 05's civil and abatement remedies.
Violations & Fines
A violation of the 1,000-foot buffer is enforced the same way as the rest of Chapter 18: Section 4-18.05 applies the Municipal Code's abatement and civil penalty provisions, including the Chapter 4-10 nuisance procedures, and Section 4-18.06 declares any violating condition a public nuisance subject to summary abatement under Code of Civil Procedure Section 731. The City Attorney may also bring a civil action for injunctive relief and civil penalties.
