Hawthorne Municipal Code Art. 1 General Provisions

This portion of the city's code restricts vibration from machines, animals, or devices (or any combination thereof) from producing vibration that exceeds the specified, measurable noise limits (as summarized in Tables N-4 and N-5, below). In general, this type of regulation is aimed at controlling stationary or on-going vibration sources that are established (in both location and periodicity). Such sources might include, for example, out-of-balance, mounted machinery, impact-intensive manufacturing equipment, or heavy construction processes. Such objective criteria give the city's enforcement officers the capability of demonstrating a measurable violation while using the defined enforcement procedures to document potential violations and to implement penalties (see also Section 9.36.050).

(Ord. 2169 § 7, 2019)

No person shall make create unnecessary vibrations are physically annoying to persons of ordinary sensitiveness or which are so harsh or so prolonged or unnatural or unusual in their use, time or place as to occasion physical discomfort. The following sections establish quantified limits to define excessively-high, unnecessary, and unusual vibration levels.
