The exemption disappears entirely on Sunday and federal holidays, and any work seeking earlier starts or later finishes needs advance approval from the Director of Community Development.
(C) Noise sources associated with or vibration created by construction, repair, remodeling or grading of any real property or during authorized seismic surveys, provided the activities do not take place between the hours of 7 p.m. and 7 a.m. on weekdays including Saturday, or at any time on Sunday or a federal holiday, without the prior approval of the Director of Community Development for expanded work hours, and provided any vibration created does not endanger the public health, welfare and safety.

Full Breakdown
Alhambra's general noise ordinance caps sound at 55 dBA in residential zones, 70 dBA in commercial zones and 60 dBA in the Mixed Use district under § 18.02.050, but § 18.02.060 exempts specific activities from that table. Subsection (C) covers construction, repair, remodeling or grading noise and vibration from authorized seismic surveys: the work is exempt from the decibel table only if it stays within 7 a.m. to 7 p.m., Monday through Saturday. Outside that window, on Sunday, or on a federal holiday, the exemption disappears and the activity is treated as an ordinary noise violation unless the Director of Community Development has approved expanded work hours in advance.
A separate exemption under subsection (D) covers property-maintenance noise, which runs 7 a.m. to 6 p.m. on weekdays and Saturday and 9 a.m. to 5 p.m. on Sunday, a Sunday window construction gets none of. A contractor whose project cannot finish inside the standard hours can apply for a temporary exception under § 18.02.110: the application goes to the Director of Development Services with a nonrefundable fee set by City Council resolution, and the Director refers it to the Planning Commission within 30 days for a hearing that can approve extended hours subject to conditions.
Planning Commission decisions on exceptions are appealable under § 23.76.090. None of these exemptions reach noise whose vibration endangers public health, welfare or safety, which subsection (C) expressly excludes from relief.
Violations & Fines
Construction noise outside the permitted hours loses its exemption and becomes a violation of Title XVIII, an infraction under § 18.02.120(A) punished as set out in § 1.12.011. The city issues a written notice fixing a deadline to correct the condition before further enforcement under § 18.02.120(B). An uncorrected or repeated violation is declared a public nuisance under § 18.02.120(C) and may be abated by injunction or restraining order in addition to infraction penalties.
