Full Breakdown
Mission caps noise from nonresidential (commercial and industrial) properties at 65 dB at all times: there's no separate daytime/nighttime split like many cities use. The limit applies citywide and reaches into the extraterritorial jurisdiction within 500 feet of the city limits. The Police Department measures from the property line closest to where the noise originates, using a calibrated sound level meter; if levels can't be metered reliably, officers can rely on trained judgment to call a violation. Businesses that expect to exceed the limit (construction, events, industrial processes) can apply to the city manager and police chief for a special exception permit.
Violations & Fines
Exceeding 65 dB from a nonresidential property is a Class C misdemeanor citation; repeat violations (more than two in six months) also bar the property from getting a special exception.
