St. Clair County has no ordinance specifically limiting leaf blowers. Their noise is governed only as a general nuisance and by the Illinois Pollution Control Board's sound limits. Some cities set hours for power yard equipment, so check your municipality.
Neither the St. Clair County Zoning Ordinance nor county nuisance code names leaf blowers, hours of use, or a gas-vs-electric distinction. In unincorporated areas, leaf-blower noise is addressed only if it becomes an unreasonable disturbance under the county nuisance provisions or exceeds the Illinois Pollution Control Board octave-band limits in 35 Ill. Adm. Code 901 (lower at night). Municipalities within St. Clair County are more likely to restrict power-equipment hours; residents of Belleville, O'Fallon, Fairview Heights and other cities should confirm any local yard-equipment window with their city clerk.
No leaf-blower-specific penalty at county level. General nuisance or IPCB noise-limit enforcement applies; state noise complaints route through the Illinois EPA.
