(Legislative History: Ordinance No. 2003-005, 3/17/03 (Sections 4-1-1100—4-1-1130); Ordinance No. 2011-006, 4/4/11 (Section 4-1-1125); Ord. No. 2024-012, 7/15/2024 (Sections 4-1-1100—4-1-1130))
It is hereby declared to be the policy of the City of San Leandro, in the exercise of its police power, to protect the peace, health, safety and general welfare of the citizens of San Leandro from loud and unreasonable, unnecessary, or unusual noises which are prolonged, unusual, annoying, disturbing and/or unreasonable in their time, place and use and which are a detriment to public health, comfort, convenience, safety, general welfare and the peace and quiet of the City and its inhabitants. It is the intention of the City Council to control the adverse effect of such noise sources on the citizens by prescribing standards prohibiting detrimental levels of noise and by providing a remedy for violations. The provisions of this Article and the remedies contained in this Code shall be cumulative and are not intended to replace any otherwise available remedies for public or private nuisances, nor any other civil or criminal remedies otherwise available. In addition, the regulations contained herein are not intended to substitute for any noise analysis conducted as a part of the City's environmental review process for discretionary permit approvals, nor is it intended to limit more strict noise control requirements for discretionary permit approvals should more strict measures be found to be necessary in order to maintain noise levels that are not detrimental to the health and welfare of the citizens of the City.
Among the unacceptable noise sources identified in the City's General Plan are mobile sources such as airplanes, commuter and freight railroads, and highway traffic and other sources which are regulated exclusively by the Federal or the State Government. While in most instances the City may not intervene to address these problems directly, it is the strong policy of the City to work with responsible government agencies and elected officials to reduce the real and damaging effects of these noise-producing activities on the quality of life of the City's residents.
(a) 
It is unlawful for any person, as defined in Section 1-14-100 of this Code, to make, continue, or cause to be made or continued within the limits of said City, any disturbing, excessive or offensive noise which causes discomfort or annoyance to reasonable persons of normal sensitivity, including loud, unreasonable, unusual, penetrating or boisterous noise, disturbance or commotion which annoys, disturbs, injures or endangers the comfort, repose, health, peace and quiet within the limits of the City, and the acts and things listed in this chapter, among others, are declared to be loud, disturbing, injurious and unreasonable noises in violation of this Chapter, but shall not be deemed to be exclusive.
(b) 
The characteristics and conditions which should be considered in determining whether a violation of this section exists include, but are not limited to, the following:
(1) 
The level of the objectionable noise.
(2) 
The level of the ambient noise.
(3) 
The proximity of the noise to residential property.
(4) 
The nature of the zoning of the area from which the noise emanates and the area where it is received.
(5) 
The population density of the area.
(6) 
The time of day or night.
(7) 
The duration of the noise.
(8)

It is the intent of this Article to prohibit all loud, unreasonable, unusual, penetrating or boisterous noise, disturbance or commotion which annoys, disturbs, injures or endangers the comfort, repose, health, peace and quiet within the limits of the City except those specifically exempted by Section 4-1-1120 and those permitted under an exception permit issued pursuant to Section 4-1-1125.

Noises by Animals. The permitting, by any person having charge, care, custody, or control of any animal, of such animal to emit any noise by any frequent or long—continued noise, which causes annoyance or discomfort to a reasonable person of normal sensitiveness in the vicinity. For the purposes of this subsection, the animal noise shall not be deemed a disturbance if a person is trespassing or threatening to trespass upon private property in or upon which the animal is situated or if the noise is for any other legitimate cause, such as someone teasing or provoking the animal. The scope of this subsection is intended to be and shall be interpreted to be broader than any similar prohibition set forth in Section 4-11-435 of this Title.

Any such permit shall be of as short duration as possible up to six months, but renewable upon a showing of good cause, and shall be conditioned by a schedule for compliance and details of methods therefor in appropriate cases.
