Los Angeles County
South Gate regulates construction noise through Chapter 11.34 (Noise Control Program) under Title 11 Zoning, administered by a designated noise control officer. Construction noise on private property is treated as on-property noise (not 'portable noise' under Chapter 7.44 per §7.44.010). The city's residential zones (Chapter 11.25) and noise control chapter set the time windows during which construction-related noise is permitted; work outside permitted hours requires a permit or is treated as a public nuisance subject to the penalties in §11.34.100. There is no statewide California construction-hours rule — limits are entirely local.

Santa Monica FAQ
When can construction happen in Santa Monica?
8 AM to 6 PM Monday through Friday, 9 AM to 5 PM Saturday. No construction on Sundays or holidays. High-impact equipment like jackhammers is limited to 10 AM to 3 PM weekdays.
Can I get a permit for after-hours construction?

South Gate FAQ
Can my contractor start work at 7 a.m. in South Gate?
Specific start-time and weekend windows are set in Chapter 11.34 (Noise Control Program). South Gate does not publish those windows in Chapter 7.44 — confirm the current allowed hours with South Gate Building & Safety or Code Enforcement (City Hall, 8650 California Ave, (323) 563-9500) before scheduling. Working outside the permitted window without a noise permit risks enforcement under §11.34.100.
Are weekends and holidays treated differently?
Yes. California cities routinely tighten or prohibit construction on Sundays and major holidays under their noise-control chapters. In South Gate the cutoff is set under Chapter 11.34; check the current version of §11.34 with Code Enforcement before scheduling Sunday work.
Do these rules apply to homeowner DIY projects?
Yes. Chapter 11.34 applies to construction-related noise from any source on private property, including homeowner-occupied work — power tools, generators, hammering. The fact that you own the property does not exempt you from the city's noise-level limits.
