Sammamish, WA Short-Term Rentals: Noise Rules (2026)

Sammamish regulates noise through its public disturbance noise chapter, SMC Chapter 8.15, which applies to any property, including a short-term rental. The city makes clear that it does not directly enforce most noise complaints. Its code-compliance program states that it does not enforce the municipal code sections covering loud noises from sources other than construction, such as horns or sirens, motor vehicles, musical instruments, car stereos, audio systems, or other public disturbance noises, and instead directs residents to contact the Sammamish Police Department non-emergency number at (206) 296-3311. As a result, party, music, and amplified-sound complaints from STR guests are handled as police-enforced public disturbance noise rather than through a dedicated STR ordinance. Separately, construction noise is limited to Monday through Friday 7:00 a.m. to 8:00 p.m. and Saturdays and holidays 9:00 a.m. to 6:00 p.m., with no construction on Sundays and major holidays; while aimed at construction, these hours illustrate the city's quiet-hours framework. Washington's RCW 64.37 does not set noise standards, but it does require an operator to provide guest contact information available to respond during the stay (RCW 64.37.030), which gives neighbors and police an operator to reach. Hosts should set clear quiet-hours house rules and keep a responsive local contact.
