Chapter 8.18 of the Oakland Municipal Code sets numerical dBA limits at the receiving property line that vary by land use and time of day. Single-family residential zones are limited to roughly 60 dBA daytime and 45 dBA nighttime; multi-family and commercial zones permit 5-10 dBA more. Sustained or impulsive sources receive a 5 dBA penalty.
Oakland's quantitative noise standard is set in Chapter 8.18. The code uses receiving-property limits, meaning the legal threshold depends on where the noise is heard rather than where it is produced. In single-family residential (R-1, RH) zones, the standard is approximately 60 dBA from 7 a.m. to 10 p.m. and 45 dBA from 10 p.m. to 7 a.m. (9 a.m. on weekends). Multi-family residential zones (R-2 through R-50) typically allow 65 dBA daytime and 50 dBA nighttime. Commercial zones permit 70 dBA daytime and 60 dBA nighttime, and industrial zones up to 75 dBA daytime and 70 dBA nighttime. The code also limits short-duration exceedances: the L25 (level exceeded 25% of the time) may exceed the base by 5 dBA, the L08 by 10 dBA, the L02 by 15 dBA, and the Lmax by 20 dBA. A 5 dBA penalty is added for noise that is impulsive (sharp peaks like hammering) or tonal (steady whines or hums), reflecting their greater annoyance. Measurements are taken with a Type 2 sound level meter at the property line of the receiving use. Inspectors from Code Enforcement and the Police Department use these standards when responding to complaints filed through Oakland 311.
