No person shall keep or harbor any animal that continuously, repeatedly, or persistently creates at any time a sound of any type that meets the criteria of § 10-602. Such sound shall be an unnecessary noise and shall be prohibited. It shall be presumed that the owner or custodian of any animal who is left unattended failed to take such action as may be necessary to keep such animal from causing an unnecessary noise if in fact such animal causes an unnecessary noise. It shall be further presumed that the owner or custodian of any animal failed to take such action as may be necessary to keep such animal from causing an unnecessary noise, if such owner or custodian has twice been previously advised in writing that such animal is causing an unnecessary noise.
It is unlawful for any property owner, or other person with permanent or temporary control, occupancy, or possession of property, to allow or permit a person or animal or group of persons or animals to create an unnecessary noise as defined in this article. The property owner, or other such person with permanent or temporary control, occupancy, or possession of property, shall be responsible for abatement of unnecessary noises occurring on that property, and failure to do so shall be a violation of this article.
(a) 
The Mayor or his designee may, upon advance request, grant a specific exception license for a single or repeated event with respect to the prohibitions of this article, but it shall be subject to such conditions as he or she deems appropriate. The Mayor or his or her designee may require as a condition, among others, that the applicant secure prior written approval of adjacent residents or such other persons as the Mayor deems appropriate.
(b) 
Nothing in this article shall prohibit noise that is a necessary accompaniment to public safety functions, including security alarms and emergency repair functions by public utilities or other contractors, and to equipment associated with air conditioning, pool maintenance, snow removal, or emergency repair equipment.
Anyone causing an injurious noise or an unnecessary noise or anyone failing to immediately abate an unnecessary noise after being requested by law enforcement authorities to do so shall be ticketed by law enforcement for violation of this article. Upon a first conviction for a violation of this article, the court shall assess a fine of not less than $50 and/or up to one month in jail. Upon a second conviction, the court shall assess a fine of not less than $150 and/or up to one month in jail. Upon a third or subsequent conviction, the court shall assess a fine of not less than $250 and/or up to one month in jail. No prior conviction shall be considered in determining the penalty to be assessed if 24 months have elapsed between the date of the violation and the date of the conviction next immediately preceding the sentencing date. Each occurrence of a violation, or in the case of a continuous violation each day a violation occurs or continues, constitutes a separate offense and shall be punishable as such hereunder.
