Fremont, CA Noise Ordinances: Construction Hours (2026)

Fremont Municipal Code Section 18.160.010 sets two different construction-hour schedules depending on proximity to sensitive uses. For any development project within 500 feet of a residence, lodging facility, nursing home or inpatient hospital, construction activity is limited to 7:00 a.m. to 7:00 p.m. on weekdays and 9:00 a.m. to 6:00 p.m. on Saturdays or holidays, and Sunday construction is banned outright. Projects that are not within 500 feet of those uses get a wider window: 6:00 a.m. to 10:00 p.m. on weekdays and 8:00 a.m. to 8:00 p.m. on weekends or holidays. Holidays are defined by Section 2.35.010. A separate, tighter rule applies to homeowners: resident homeowners and their uncompensated volunteer workers doing construction on their own single-family detached home are limited to 7:00 a.m. to 8:00 p.m. on weekdays and 8:00 a.m. to 8:00 p.m. on weekends.

The section exempts construction necessary to prevent or repair an emergency condition, as determined by the city manager's designee, and gives the city manager's designee authority to modify the hours in three situations: to facilitate staff supervision or inspection or comply with more restrictive code, state, or federal law; when nearby uses or site conditions support a finding that modified hours would produce an equal or superior level of comfortable enjoyment of life and property for the community; or when the project sits in a right-of-way, easement, or public property and modified hours would minimize disruption, such as by improving traffic flow. Permitted projects must post the allowable construction hours on the cover sheet of the construction plans, and any project requiring a permit, other than additions or alterations to single-family homes, must display an all-weather notice board near the public right-of-way with project information, allowable hours, and city staff contact information for the duration of construction.
