9.52.020 - Findings, purpose and scope.¶
The City Council of the City of Richmond hereby finds and declares as follows:
WHEREAS, exposure to unnecessary and unwanted noise produces significant medical, social and economic effects as evidenced by the following:
• Noise is arguably the most common - and least regulated - form of environmental pollution; 1 and
• Noise represents the principal avoidable cause of permanent hearing impairment worldwide; 2 and
• Hearing impairment leads to interpersonal, school and job related problems, with lasting detrimental social and economic effects; 3 and
• Community noise interferes with sleep, leads to fatigue, increases irritability, impairs performance, and causes accidents; 4 and
• Noise increases blood pressure and heart rate and may cause abnormal rhythms, whether awake or asleep; 5 and
• Noise provokes strongly felt annoyance, creating stress that leads to disease and degrades quality of life; 6 and
• Current studies from the European Union confirm that 3% of all fatal heart attacks are induced by noise; 7 and
• Noise provokes unwanted behaviors, leading to antisocial acts or unwillingness to help others; 8 and
• Governmental studies confirm that substantial portion of the population is exposed to noise levels that are unhealthy, interfering with learning, task performance, leisure, and sleep; 9 and
• Studies in the European Union show that noise decreases housing prices and median home costs, imposes restrictions on land use, and increases time lost from work; 10 and
WHEREAS, the 1999 United States Census reported that Americans named noise as the number one problem in neighborhoods, of greater concern that crime or other bothersome conditions, noting that:
• Noise levels have risen at least six-fold in major U.S. cities, and will continue to grow because on increases in population, and the number, variety, and mobility of sources of noise; 11 and
• Most people object to the intrusion of unwanted noise into their homes, and on their streets, neighborhoods, and parks; and
• In 1974, the Environmental Protection Agency estimated that nearly 100 million Americans lived in areas where the daily average noise levels exceeded those identified as being safe; 12 and
• The number of people exposed to unhealthy levels of noise is far greater than it was in 1972 at the time the Noise Control Act was passed and the degree of oversight and control is unquestionably less; 13 and
WHEREAS, noise is best controlled at the source; 14 and
WHEREAS, community noise intrudes into homes, neighborhoods, and parks; and
WHEREAS, between June 2004 and August, 2005, the Quality of Life Hotline in New York City received 410,000 complaints; 15 and
WHEREAS, since the air, a universally shared resource, is a commons, owned by none but used by all; 16 and
WHEREAS, individuals and businesses, either willfully or ignorantly, assume they have the right to emit noise into the air, thereby adversely affecting all who have no choice but to hear it; 17 and
WHEREAS, domestic tranquility is one of the six guarantees in the United States Constitution; and
WHEREAS, in 1972, the Noise Control Act was passed by the Congress, declaring - - - "it is the policy of the United States to promote and environment for all Americans free from noise that jeopardizes health and welfare." - - -; 18 and
WHEREAS, it is the responsibility of government at all levels to protect citizens from the unwanted effects of noise and other forms of pollution; and
NOW THEREFORE, it is the intent of the City Council in enacting this ordinance, to provide for the public health, safety, and welfare by discouraging unwanted and unnecessary, noise of all types, and by protecting the public from nonconsensual exposure to community noise in and around the City of Richmond.

9.52.100 - Alternative use of maximum noise limits by dBA levels.¶
It addition to determining noise violations under the standard set forth elsewhere in this chapter, the enforcing officer may alternatively use the maximum decibel ("dBA") levels to determine a violation of this chapter. The standard chosen by the enforcing officer for the specific incident shall be the sole means used to determine if a violation has occurred. Neither standard shall be considered superior, nor controlling, nor preempt the other.
If the enforcing officer selects the alternative standard to using the dBA level standard, evidence of dBA levels within the maximum permitted levels may be presented in defense of the charged violation only if the proffered dBA reading was taken at the exact time and location and under identical conditions, including wind, and temperature, as those encountered by the enforcing officer encountered at the time he or she charged the violation and by a decibel meter with valid current calibration records and evidence of the training or expertise of the person offering the dBA reading as evidence of compliance with this chapter.
(a) It shall be unlawful to maintain, permit, allow or suffer any use or activity that creates noise levels which exceed the following standards:
| Zoning District: | Maximum Noise Level in dBA (levels not to be exceeded more than 30 minutes in any hour) | Maximum Noise Level in dBA (levels not to be exceeded more than 30 minutes in any hour) | Maximum Noise Level in dBA (level not to be exceeded more than 5 minutes in any hour) |
|---|---|---|---|
| Measured at Property Line or District Boundary | Measured at Any Boundary of a Residential Zone | Between 10 PM and 7AM***, Measured at Any Boundary of a Residential Zone | |
| Single-Family Residential | 55 | ||
| Multifamily Residential | 55 | ||
| Commercial | 70 | 60 | 50 or ambient noise level |
| Lt. Industrial and Office Flex* | 70 | 60 | 50 or ambient noise level |
| Heavy and Marine Industrial | 75 | 65 | 50 or ambient noise level |
| Public Facilities and Community Use | 65 | 60 | 50 or ambient noise level |
| Open Space and Recreational Districts | 65 | 60 | 50 or ambient noise level |
* For M-1 and M-2 the measurement will be at property lines.
** For M-3 and M-4 the measurement will be at boundary of the district.
*** Restricted hours may be modified through condition of an approved conditional use permit. Section subsections of this chapter also provide for additional restricted hours and the most restrictive hours shall be controlling.
(b) In determining whether any noise exceeds the maximum exterior noise limits set forth in this section, measurements shall be taken at the property line of the property from which the noise emanates, except that for noise emanating from property in an M-3 or M-4 zoning districts, measurement shall be taken at boundary of the zoning district in which the property is located.
(c) No person shall operate or cause to be operated within a dwelling unit, any source of sound that causes the sound level when measured inside a neighboring receiving dwelling unit to exceed the allowable noise level, for any period of time.
(d) In the event the noise, as judged by the enforcing authority, contains a steady, pure tone such as a whine, screech or hum, or is an impulsive sound such as hammering or riveting, or contains music or speech, the standard limits set forth above shall be reduced by 5 decibels.
(e) The exterior noise limits for any source of noise within any residential zone shall be reduced by 10 dBA between 10:00 p.m. and 7:00 a.m. The exterior noise limits for any source of noise in any zone other than a residential zone shall be reduced between 10:00 p.m. and 7:00 a.m. so that when the noise measured at the property line of a "noise-sensitive use" does not exceed 50 dBA. The interior noise level from exterior sources in any residential bedroom for steady state continuous noise with windows open between 10:00 p.m. and 7:00 a.m. shall not exceed 30 dBA. Noise from sources not under local jurisdiction such as freeways and aircraft shall be exempt.
(Ord. No. 14-11 N.S., § 2, 5-17-2011; Ord. No. 15-18 N.S., § I, 6-19-2018)
9.52.110 - Temporary construction activity.¶
Where technically and economically feasible temporary construction activity shall be conducted in such a manner that the maximum sound levels at affected properties shall not exceed the following dBA levels:
(a) Mobile construction equipment—Maximum sound levels for nonscheduled, intermittent, and short term operation of less than 15 days:
