Full Breakdown

Chapter 164 defines "Nighttime hours" as beginning 8:01 p.m. Monday-Saturday and 5:01 p.m. Sunday and federal holidays, ending 7:59 a.m. and 9:59 a.m. respectively (§ 164-3). The zone-to-zone table in § 164-5B(1) then drops the allowable residential-to-residential noise level from 55 dBA in daytime to 45 dBA during those nighttime hours, effectively acting as Stamford's quiet-hours rule. The Director of Health or Chief of Police may take sound-level measurements to document a violation.

Violations & Fines

A $250 fine per offense applies under § 164-10; the Director of Health or Chief of Police can inspect, test and measure noise, and may seek a court warrant if access is refused.
