Noblesville, IN Noise Ordinances: Leaf Blower Rules (2026)

Section 93.25(F) of the Noblesville Code of Ordinances lists fourteen categories of sound exempted from the city's general noise limits, and item (2) covers "lawn mowers, leaf blowers, weed trimmers, garden tractors, and power tools, when properly muffled, between the hours of 7:00 a.m. and 10:00 p.m. only." Outside that daily window, the same equipment is judged against the general noise standards in § 93.25(C): sound may not exceed the chart limit (60 dB(A) daytime/50 dB(A) nighttime in commercial districts, 55/50 in residential districts) for more than five minutes in any fifteen-minute period, or 70 dB(A) at any time, measured from 50 feet away.

Because the exemption is muffling-conditioned, an unmuffled or modified blower can be cited even during permitted hours if it exceeds those chart levels. Section 93.25(G) sets escalating fines for any violation of the section: up to $500 for a first offense in a commercial or industrial district and up to $250 in a residential district, rising to $1,000/$500 for a second offense within two years, $2,000/$1,000 for a third, and a flat $2,500 cap for a fourth or later offense in any district. Under § 93.25(H), citations may be issued by any City Code Enforcement Officer or by a sworn Noblesville Police Department officer, and § 93.25(A) makes clear the section binds landholders across the city outside the legal description carved out in Ordinance 40-5-03.
