Florissant, MO Code Violation Reporting: Common Violations (2026)

Section 605.454, the definitions section of Chapter 605's Residential Rental Real Estate article, spells out what counts as a 'public nuisance' in Florissant by cross-referencing the specific Code sections that actually create each violation. The list includes lewd and lascivious behavior, loud music or noise under Section 210.750, failure to maintain property under Section 213.020 and Chapter 510, graffiti under Section 210.1300, garbage, rubbish and litter under Sections 220.020 and 213.020, tall weeds and grass under Section 213.030, physical conditions that threaten health, safety or welfare under Section 510.230, dangerous buildings or conditions threatening physical health under Section 213.010, rodent and insect infestation under Section 213.030, derelict vehicles and equipment under Section 213.030, flammable or hazardous materials endangering public safety under Section 213.030, unlicensed or inoperable vehicles left outside an enclosed area under Sections 395.020 and 395.030, and obstruction of surface storm water drainage under Section 535.030.

These definitions apply in interpreting and enforcing the Code generally and carry real consequences for rental property: Section 605.461(A)(1) lets the Director of Public Works suspend a rental license once a property is found out of compliance with property maintenance codes on more than three occasions within six months without correction, and Section 605.461(A)(3) allows suspension or revocation after three or more nuisance incidents involving tenants or occupants within twelve months. A resident can report any of these conditions to the Florissant Department of Public Works, which enforces the maintenance and nuisance sections, or to the Police Department for the noise, vehicle and graffiti provisions.
