Fremont sets exterior noise limits of 55 dBA daytime and 50 dBA nighttime at residential property lines under FMC Chapter 5.30.
Fremont Municipal Code Chapter 5.30 establishes a comprehensive decibel-based noise standard. Residential zones: 55 dBA daytime (7 AM to 10 PM) and 50 dBA nighttime at property lines. Commercial zones: 65 dBA daytime and 60 dBA nighttime. Industrial zones: 70 dBA daytime and 65 dBA nighttime. When a receiving property is in a more restrictive zone than the source, the stricter limit applies. Measurements use an ANSI Type 1 or Type 2 sound level meter with A-weighting and slow response. Code Enforcement officers respond with calibrated meters for persistent complaints. Short-duration peaks (under 10 seconds) are evaluated separately. The ordinance provides exemptions for emergency vehicles, school activities, and permitted events. Violations trigger administrative citations starting at 100 dollars.
Contact your local code enforcement office for specific penalty information.
