Cupertino has no separate industrial-noise chapter; nonresidential (commercial, office, industrial) sources are held to CMC 10.48.040 limits of 65 dBA daytime and 55 dBA nighttime at the receiving property, plus the general noise-disturbance ban.
Cupertino Municipal Code Chapter 10.48 has no stand-alone industrial-noise ordinance; instead, industrially and commercially zoned properties are governed by the general Section 10.48.040 standard, capping a nonresidential land use at 65 dBA daytime and 55 dBA nighttime at the receiving property line. Related provisions apply: Section 10.48.055 limits off-street vehicle idling to three minutes per hour, and Section 10.48.062 prohibits vehicular deliveries and pickups to or from commercial establishments across private roads adjacent to residential property between 8:00 p.m. and 8:00 a.m. weekdays and 6:00 p.m. and 9:00 a.m. weekends and holidays. Any unreasonable noise disturbance is prohibited under Section 10.48.060, and the Noise Control Officer may condition noise-producing city contracts on compliance.
Industrial or commercial noise exceeding CMC 10.48.040, or a prohibited nighttime delivery under 10.48.062, is a violation of Chapter 10.48, a misdemeanor punishable per CMC Chapter 1.12 (CMC 10.48.070).
