St. Louis's Public Conduct: The Rules That Matter

Every city handles public conduct a little differently. In St. Louis, Missouri, there are 7 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Public Marijuana Use

St. Louis directs police away from enforcing most marijuana possession laws, but openly displaying or consuming marijuana in public stays a full enforcement target under § 11.61.020.A.5.

Key details: Governing ordinance: No. 71429, § 3 (12-13-2021). General policy: no enforcement, ≤2 oz / 6 plants. Public-use exception: resources may still be used. Safe harbor: private residential property, with permission.

Public display or consumption falls outside the low-enforcement policy, so ordinary marijuana possession/use enforcement, citation or arrest under applicable state or local law, remains in play.

Aggressive Panhandling

St. Louis bans aggressive panhandling outright and bars all panhandling near banks, schools, transit stops, and building entrances, plus after dark and in groups of two or more.

Key details: Bank/ATM buffer: 50 feet. School buffer: 50 feet. Curfew: 8 p.m.-7 a.m. (DST). Group panhandling: banned for 2+ persons. Third-offense max: 30 days jail.

First offense draws a warning only. A second violation brings a court summons and possible fine of $50-$500 or community service; a third or later violation adds up to 30 days imprisonment.

Compared to other cities, St. Louis takes a harder line on aggressive panhandling. The enforcement and penalty structure reflects that.

Public Alcohol Use

St. Louis allows open containers of alcohol on public sidewalks and streets in much of downtown and Soulard, but bans drinking in vehicles, city parks (without permit), and during glass-bottle restrictions.

Key details: Open container: Allowed on most sidewalks. State vehicle ban: MO §577.017. Glass restriction: Many districts. Parks: Permit required.

Drinking in a vehicle, carrying glass in a glass-restricted zone, or consuming alcohol in a park without a permit can trigger fines and seizure of the alcohol.

The rules around public alcohol use in St. Louis lean permissive, but that does not mean anything goes.

Jaywalking

In St. Louis's central traffic district, pedestrians must cross at a crosswalk. Elsewhere, crossing outside a crosswalk is legal only if the nearest one is more than 150 feet away, and jaywalkers must yield to vehicles.

Key details: Central traffic district: No crossing outside a crosswalk. Elsewhere in city: Legal only if crosswalk is 150+ ft away. Mid-block crossing: Must yield right-of-way to vehicles. Diagonal crossing: Barred without traffic-control authorization. Fine payment window: 7 days to Traffic Violation Bureau.

Police issue a violation notice under § 17.20.140. The pedestrian pays a fine set by the municipal courts, or mails payment, to the Traffic Violation Bureau within 7 days, or is issued a summons.

Compared to other cities, St. Louis takes a harder line on jaywalking. The enforcement and penalty structure reflects that.

Public Urination

Urinating or defecating in public anywhere in St. Louis is a fine-and-jail offense, with narrow exceptions only for young children and a verified medical condition.

Key details: Governing section: Rev. Code § 15.39.010. Exceptions: Children 5 and under; verified medical condition. Minimum fine: $100. Maximum penalty: $500 fine or 90 days jail.

Fine of $100 to $500, up to 90 days in jail, or both, under § 15.39.020.

Compared to other cities, St. Louis takes a harder line on public urination. The enforcement and penalty structure reflects that.

Loud Party Ordinance

St. Louis makes it a misdemeanor to disturb the peace with noisy, riotous, or disorderly conduct, and separately holds an owner or occupant liable for permitting such disturbances on premises they control.

Key details: Governing section: St. Louis Code Section 15.46.030. Host liability: Owner/occupant liable if they permit it. Penalty source: General penalty, Section 1.12.010. Max fine: $500 (min $1). Max jail: 90 days.

Guilty of a misdemeanor under the citywide general penalty, Section 1.12.010: a fine of $1 to $500, up to 90 days in jail, or both -- each day of ongoing disturbance is a separate offense.

Loitering Rules

St. Louis bans loitering, idling, or playing in any public park or playground from 10 p.m. to 6 a.m. year-round, with exceptions for permit holders and through-travelers.

Key details: Curfew hours: 10 p.m.–6 a.m., citywide. Fine range: $1.00–$500.00. Exemptions: Permits, through-travel, city staff. Vehicle parking: Also banned 10 p.m.–6 a.m.. Stricter local curfews: Mt. Pleasant, Buder, other parks.

Violating the park curfew is punishable by a fine of not less than $1.00 nor more than $500.00 per § 22.18.050. The Parks Department is required to post the curfew notice in every park and playground.
