Full Breakdown
National City has no single quiet-hours section. The ten p.m. to seven a.m. window appears in several prohibitions in Chapter 12.10 (Prohibited Acts) of the Noise Control Ordinance, and it matches the night column of the Table III exterior limits in Chapter 12.06.
Section 12.10.060 covers radios, television sets, phonographs, drums, musical instruments and similar devices. Between ten p.m. and seven a.m. they cannot exceed the interior limits of Table IV across the wall separating attached multifamily units, or the exterior limits of Table III across a residential or commercial real property line. At any hour they cannot violate Section 12.06.020. Table III night limits are 45 dB(A) for residential land with fewer than 9 dwelling units, 50 for multi-unit residential of 9 units or more, 60 for commercial, 70 for light industry and 80 for heavy industry.
Section 12.10.300 covers domestic power tools: no mechanically powered saw, sander, drill, grinder, lawn or garden tool or similar tool between ten p.m. and seven a.m. so as to create a noise disturbance across a residential or commercial property line exceeding the limits in Section 12.06.020. Section 12.10.140 applies the same window to loading and unloading boxes, crates, containers, building materials and garbage cans, and Section 12.10.200 to powered model vehicles.
Animals get a tighter clock. Section 12.10.120 bars an animal or bird from howling, barking, meowing or squawking across a residential or commercial property line, or within a noise sensitive zone, for more than three minutes between ten p.m. and seven a.m.; at other times the limits are ten consecutive minutes or a total of fifteen minutes in any sixty minute period. Outdoor amplified sound has its own earlier window, nine p.m. to eight a.m., under Section 12.10.080.
Section 12.10.040 treats any noise audible at a distance of fifty feet or more from its source as prima facie evidence of a noise disturbance. The planning commission can grant time-limited exceptions under Chapter 12.16.
Violations & Fines
A nuisance noise disturbance is an infraction for a first violation under Section 12.18.020, and repeat violations can be prosecuted as misdemeanors. Section 1.20.010 caps an infraction fine at one hundred dollars for a first violation, two hundred dollars for a second within one year, and five hundred dollars for each additional violation within one year. The chief of police enforces nuisance noise and normally starts with an abatement order that can require the noise to stop immediately.
