Industrial zones in Palo Alto are capped at 70 dBA daytime and 65 dBA at night at the property line, with tighter limits where industrial abuts residential under PAMC 9.10.
Palo Alto Municipal Code section 9.10.040 sets exterior noise limits by zoning district. Manufacturing and research park zones (Stanford Research Park, East Bayshore) may emit up to 70 dBA during daytime hours (7am-10pm) and 65 dBA at night. However, where industrial property abuts a residential zone, noise at the shared property line must not exceed the residential limit (60 dBA day, 50 dBA night). HVAC units, backup generators, and loading docks are common sources of complaints. The Environmental Services Department can require noise studies and mitigation including sound walls, enclosures, or time-of-day operational restrictions. Exceeding limits triggers abatement notices and administrative fines.
Contact your local code enforcement office for specific penalty information.
