Summary

St. Louis County makes it a crime to urinate or defecate in public view anywhere in the unincorporated county. Section 713.070 of the Vice and Morality Code lists it alongside public sex acts and indecent exposure, all punishable by up to a $1,000 fine or a year in the County Jail. Breastfeeding and licensed dramatic performances are expressly exempt from the ban.

City-specific rules exist: Florissant has its own public urination rules that differ from St. Louis County's county-level regulations. If you live in Florissant, check the city-specific page instead.

Full Breakdown

The Vice and Morality Code (Chapter 713) applies only in the part of St. 020); a city with its own police power enforces its own indecency ordinance instead. ' The section carves out three exceptions: artistic or dramatic performances that are otherwise lawful under Chapter 706's obscenity code, exposure incident to breast-feeding an infant, and exposure of a prepubescent female's breasts. Enforcement runs through the St. 075, if they refuse a police order to move on. 080: a fine not exceeding $1,000 or up to a year in the County Jail, or both, with each incident charged as a separate offense.

Because the statute does not require intent to offend, a single instance witnessed by any passerby in a public street, park or parking lot is enough to support a citation; officers do not need a complaining witness who felt targeted, only public visibility of the act itself.

Violations & Fines

A first public-urination or public-defecation citation under §713.070 is punished the same as the chapter's other sex-offense provisions: a fine of up to $1,000, up to one year in the County Jail, or both, under §713.080, with each occurrence treated as a separate offense. Refusing a police order to leave the area while suspected of intending the same conduct adds a separate loitering charge under §713.075.

Frequently Asked Questions

Is public urination illegal in St. Louis County?
Yes. Section 713.070 of the Vice and Morality Code makes it unlawful to urinate or defecate while in public view anywhere in the unincorporated county, treating it the same as other acts of public indecency listed in the same sentence. A conviction carries up to a $1,000 fine or a year in the County Jail under §713.080.
Does this law apply inside cities like Florissant or Ballwin?
No. Chapter 713 states in §713.020 that it applies only to the area of St. Louis County outside incorporated cities, towns and villages. A city such as Florissant, Ballwin or Kirkwood enforces its own municipal indecency ordinance instead of the county code.
Are there any exceptions to the public urination ban?
Section 713.070 exempts artistic or dramatic performances that are lawful under the county's separate obscenity code, exposure necessarily incident to breastfeeding an infant, and exposure of a prepubescent female's breasts. Outside those three carve-outs, any act done in public view is covered.
