Summary
Daly City's municipal code sets no construction-hour limits, maximum sound levels, or vibration standards, a gap the City's own environmental review confirms. The general nighttime rule in Section 9.22.030 still effectively bars construction noise audible off-site from 10:00 p.m. to 6:00 a.m.
The Daly City Municipal Code does not contain regulations for the maximum sound level or hours of construction activities, nor does it contain vibration standards.
Full Breakdown
The City's Serramonte Shopping Center Expansion DEIR (March 2015) states plainly that the Daly City Municipal Code does not contain regulations for the maximum sound level or hours of construction activities, nor vibration standards. Construction noise is instead managed project-by-project through CEQA mitigation measures and permit conditions of approval. The general disturbing-the-peace rules of Chapter 9.22 remain applicable: Section 9.22.030 prohibits any noise audible beyond the property of origin between 10:00 p.m. and 6:00 a.m., and Section 9.22.010 prohibits disturbances of the public peace at any hour. For new buildings, interior noise standards come from Title 24 of the California Building Code, which requires habitable rooms in new construction to meet a 45 dBA CNEL/Ldn interior limit.
Violations & Fines
There is no construction-hours citation to issue, but construction noise heard off-site between 10:00 p.m. and 6:00 a.m. violates Section 9.22.030, and disruptive work at any hour can be enforced as disturbing the peace under Section 9.22.010.
