Industrial and commercial properties in Mountain View must comply with stationary noise source limits measured at property lines, with conditions enforced through zoning and use permits.
Industrial noise is regulated by Mountain View Zoning Code and Chapter 21 with strict limits at property lines adjacent to residential zones. Typical limits are 60 dBA daytime and 50 dBA nighttime when measured at a residential property line. HVAC systems, loading docks, compressors, and backup generators must be screened or muffled to comply. Major tech employers such as Google, LinkedIn, and Intuit have conditional use permits with specific noise monitoring requirements. Warehouses and light industrial uses in the North Bayshore and San Antonio areas must not operate noise-generating loading activities between 10pm and 7am without a variance. Continuous violations can trigger use permit review and potential revocation through Planning Commission hearings.
