Full Breakdown
San Diego Municipal Code §59.0303(n) bars any privately owned motor coach from idling its engine for more than fifteen minutes while parked, standing, or stopped on a public way inside the Ballpark District. The district is a designated special-event venue activated three hours before Padres games and City events at PETCO Park and lasting until one hour after. A motor coach making a temporary stop solely to load or unload passengers may idle only as long as reasonably necessary for that purpose. The rule targets tour and charter buses circling the stadium, not private cars, and does not apply citywide or outside event windows.
Violations & Fines
Violating the Ballpark District idling ban is an infraction under SDMC §59.0303; City Manager designees can cite drivers who let motor coaches idle past fifteen minutes during a designated event window.
