Sammamish has no leaf-blower-specific ordinance - no gas-blower ban, no separate decibel cap, and no dedicated time-of-day rule for yard equipment. Leaf blowers are governed only by the general public-nuisance standard in SMC 8.15.020, which bars loud and raucous noise that unreasonably interferes with neighboring residential use.
A search of Sammamish's noise code finds no provision singling out leaf blowers, lawn mowers, or other powered landscaping equipment. SMC Chapter 8.15 (Public Disturbance Noise), the city's core noise ordinance, lists specific nuisance sources - engine/vehicle noise, horns and sirens, loud and raucous noise, and over-amplified audio audible beyond 75 feet - but does not set hours or decibel limits for leaf blowers or yard tools. As a result, leaf blowers in Sammamish are constrained only by the catch-all standard in SMC 8.15.020, which makes it unlawful to allow sound from property that is a public nuisance, including "any loud and raucous noise which unreasonably interferes with the use of any business or residential property, school or place of religious worship." Commercial landscaping noise tied to construction sites is also subject to the construction-hours limits in SMC 16.05.030. For ongoing stationary equipment noise, Washington's state environmental noise rules (WAC 173-60-040) provide a backstop, capping residential receiving-property noise at 55 dBA and reducing that limit by 10 dBA between 10 p.m. and 7 a.m. Sammamish has not adopted the gas-blower phase-outs or designated quiet hours seen in some other jurisdictions.
There is no leaf-blower citation in Sammamish code. Excessively loud blower use that unreasonably disturbs neighbors can be cited as a public nuisance under SMC 8.15.020 (civil fine up to $250 first offense, up to $1,000 for repeats within 12 months). Stationary equipment noise exceeding the WAC 173-60-040 limits, especially the reduced 10 p.m.-7 a.m. nighttime cap, may draw state-law enforcement.
