Jefferson County has no leaf-blower-specific rule. A leaf blower is treated as any non-vehicular residential noise source, so it must not exceed 55 dB(A) (7 a.m.-7 p.m.) or 50 dB(A) (7 p.m.-7 a.m.) at 25 feet from a property line.
There is no county ordinance banning leaf blowers or setting gas-vs-electric limits in unincorporated Jefferson County. Instead, leaf blowers fall under the general Noise Abatement Policy prohibition on operating any device that makes sound above the permissive levels. In a residential zone that means the 55 dB(A) day and 50 dB(A) night caps, dropping to 50/45 dB(A) for periodic, impulsive, or shrill noise. Individual cities in Jeffco may adopt their own equipment rules.
Operating equipment above the residential limits is a Class 2 Petty Offense; $30 per offense up to a $300 maximum, plus court costs.
