Smoke Detectors

Failing to install, interconnect or properly power required smoke alarms is a violation of the Property Maintenance Code subject to the penalties of Section 100.080 under Section 109.4, with each day the condition continues after notice served treated as a separate offense.

Fire Pits & Backyard Fires

Florissant allows recreational wood fires only in a metal fire pit, a covered stone or brick pit no larger than 3 feet across, or a chiminea, per City Code Section 220.100(B). Fires are barred during a National Weather Service Red Flag Warning and permitted only between 10:00 a.m. and 11:00 p.m.

Recreational fires that don't meet the pit type, size, firewood-length or curfew rules, or that burn during a Red Flag Warning, violate Section 220.100(B) and fall under the City's general penalty, Section 100.080: a fine of up to $1,000, up to three months in jail, or both, with each day of a continuing violation charged as a separate offense.

Fireworks

Florissant bans the sale, possession, use, and discharge of fireworks within city limits under Code of Ordinances Section 215.020, with narrow exceptions for licensed nonprofit pyrotechnic displays. Violators face fines under Section 100.080 and confiscation of the fireworks, and parents can be liable if they let a minor under 17 handle them.

A violation of the fireworks article is punished under the City's general penalty provision, Section 100.080, for each separate offense. Beyond a fine, Section 215.050 lets the City seize, confiscate, and hold fireworks for destruction or disposal pursuant to a court order. A parent or guardian who permits a minor under seventeen to possess or use fireworks faces the same penalties under Section 215.060, and interfering with a permit inspection under Section 215.040 is separately punishable.
