particular use. If the setback for a storage shed is 20', then the setback for your coop should be the same. The birds should be allowed to free range in your yard as long as they are not wandering into neighbor's yards.
Nuisances should be addressed per the nuisance, be it noise, odor, noxious weeds, etc., not the cause of the nuisance. If you can build a soundproof chicken coop so that a roosters middle of the night and o-dark-hundred crowing cannot be easily heard by neighbors, then you should be allowed to have roosters.
Sec. 20-6. Allowable noise levels.
(a) It is unlawful for any person to create any noise which would cause the noise level measured at either the property line or the area of the property affected by the noise emission to exceed the following community noise standards:
Noise Standard
Zone Time dB(A)
Residential 10:00 p.m. 7:00 a.m. 45
7:00 a.m. 10:00 p.m. 55
Commercial 10:00 p.m. 7:00 a.m. 55
7:00 a.m. 10:00 p.m. 65
Industrial 10:00 p.m. 7:00 a.m. 60
7:00 a.m. 10:00 p.m. 70
(b) If the measurement location is on a boundary between two (2) zoning districts, the lower noise standard shall apply.
(c) If the ambient noise level in a residential zoned location is measured and found to be forty (40) dB(A) or less between the hours of 10:00 p.m. and 7:00 a.m., then the actual ambient noise level will be community noise standard.
(d) If the ambient noise level in any zoning district is measured and found at any time to be in excess of the community noise standards described in subsection (a) of this section, then the actual ambient noise level will be the community noise standard.
(e) A noise level which exceeds the community noise standard by five (5) dB(A) or more, when measured at the affected area, the nearest property line, or, in the case of multiple-family residential buildings, when measured anywhere in one dwelling unit with respect to a noise emanating from another dwelling unit or from common space in the same building, shall be deemed a prima facie violation of this chapter.
and
Sec. 20-11. Unnecessary noise.
(a) Notwithstanding any other provision of this chapter, and in addition thereto, it shall be unlawful for any person without justification to make or continue, or cause or permit to be made or continued, any unnecessary, excessive or offensive noise which disturbs the peace or quiet of any neighborhood or which causes discomfort or annoyance to any reasonable person of normal sensitiveness residing in the area.
(b) The factors which will be considered in determining whether a violation of the provisions of this section exists will include, but not be limited to, the following:
(1) The volume of noise;
(2) The intensity of the noise;
(3) Whether the nature of the noise is usual or unusual;
(4) Whether the origin of the noise is natural or unnatural;
(5) The volume and intensity of the background noise, if any;
(6) The proximity of the noise to residential sleeping facilities;
(7) The nature and zoning of the area within which the noise emanates;
(8) The density of the inhabitation of the area within which the noise emanates;
(9) The time of the day or night the noise occurs;
(10) The duration of the noise;
(11) Whether the noise is recurrent, intermittent or constant;
(12) Whether the noise is produced by a commercial or noncommercial activity;
(13) Whether it is a pure tone noise; or
(14) Whether it is an impulse noise.
