Full Breakdown
Sec. on Sundays and holidays. Inside those hours, a leaf blower or similar power tool isn't measured against Table 1's residential caps of 60 dB(A) by day and 55 dB(A) at night. on weekdays, and outside the later Sunday and holiday window. The Jefferson Parish Sheriff's Office enforces this section under Sec. 20-102(d). A related but separate rule, Sec. 16-9(b), makes it unlawful to blow grass clippings, leaves, or debris onto a public street, right-of-way, or pedestrian walkway with a leaf blower unless the debris is immediately removed and containerized for composting or proper disposal, addressing where the clippings end up rather than when the blower runs.
Violations & Fines
Sec. 20-102(l) makes any violation of the noise section punishable under Sec. 1-10, the Code's general penalty: up to $1,000.00, up to six months imprisonment, or both, with each day of a continuing violation treated as a separate offense. Blowing debris into the street under Sec. 16-9(b) is a separate violation enforceable by the Department of Environmental Affairs, Sheriff's Deputies, or state and federal officials.
