Summary
San Diego makes it a misdemeanor to loiter near critical-infrastructure sites, airports, tank farms, reservoirs, power plants, gas plants and similar facilities, once the owner has posted a no-trespassing sign under the municipal code.
§52.30.2 Loitering — A Misdemeanor. It shall be unlawful for any person to loiter in the immediate vicinity or any premises posted as provided in this section and these Subsections.
Full Breakdown
SDMC §52.30.2 bans loitering "in the immediate vicinity or any premises posted as provided in this section," tied to the posting authority in §52.30 for airports, tank farms, reservoirs, power and gas plants, telephone/telegraph facilities, radio stations, railroad bridges and explosive-storage sites. §52.30.3 exempts peace officers on duty, anyone using an established public sidewalk or street, and peaceful labor-dispute leafleting. A separate provision, §52.25, bans loitering in or about a public pedestrian tunnel or underground passageway. There is no general citywide ban on loitering in public places outside these posted or tunnel settings.
Violations & Fines
Violating §52.30.2 or §52.25 is a misdemeanor enforceable by SDPD; each instance of loitering near a posted site or in a pedestrian tunnel can support a separate charge.
