Construction hours in Fremont, CA — sometimes called construction noise rules or contractor work-hour ordinances — set when contractors can run power tools, hammers, and heavy equipment.
Construction in Fremont is permitted 7 AM to 7 PM weekdays and 9 AM to 6 PM Saturdays, with no work allowed on Sundays or holidays.
Fremont Municipal Code Chapter 5.30 restricts construction, demolition, and related activity to protect residential neighborhoods from early morning and late evening noise. Permitted construction hours are 7 AM to 7 PM Monday through Friday and 9 AM to 6 PM on Saturdays. Construction is prohibited on Sundays and federal holidays except for emergency work or interior work that produces no audible noise at the property line. The Warm Springs Innovation District, Ardenwood, Mission San Jose, and Niles have active residential construction subject to these rules. Contractors working on Tesla-adjacent industrial projects or BART extension work may obtain special variances through the Building Division (510-494-4460).
