Columbia Posting bills, painting signs, etc., prohibited; exception ordinance (§ 16-163)
Chapter 16: Offenses and Miscellaneous Provisions · Article II. Code of Offenses
In short: You can't post bills or paint, write or print signs on sidewalks, streets, bridges, poles, trees, or on anyone else's property without the owner's prior consent. A sign bearing a person's or business's name is prima facie evidence that they put it there. Curb house numbers are allowed with a city permit and following the city's rules.
