Summary
Trenton imposes no fixed numeric cap on the dogs or cats a household can keep. City Code § 21-29 instead bars keeping animals in numbers, sizes, or types that create a public nuisance, judged by whether the property can adequately contain and shelter each animal alongside its human occupants. The Health Officer enforces the standard through written notice and an administrative hearing before any citation issues.
Except as a licensee to operate a kennel, pet shop or other lawful activity involving the keeping of animals, no person shall keep or house animals of any species in such numbers or of such size or innate characteristics as to constitute a public nuisance. The keeping of animals shall be deemed to be a public nuisance if the property within which they are kept is not of a size, configuration, or improved with appropriate facilities to adequately provide for the containment of all such animals or to accommodate the natural spatial needs of each individual animal, sheltered or unsheltered from the elements, while providing simultaneously for the minimal spatial needs of the regular human occupants of the property. A public nuisance shall also be deemed to exist when, by reason of the physical structure or other characteristic of the property or of an adjoining property, the public or occupants of neighboring property are exposed to an unreasonable degree of dangerous contact with the animal or of an odor or noise.

Full Breakdown
Chapter 21, Article III governs the keeping of birds and animals citywide. Section 21-23 requires that no person keep birds or animals except as the article allows, and § 21-26 conditions keeping on a Health Officer-issued license, with a $10 annual fee under § 21-28. Ordinary household pets are carved out of the licensing requirement: § 21-24 exempts 'animals kept as pets, provided they are of a species and of a number usually kept for that purpose' from §§ 21-26 and 21-28, but that exemption does not reach § 21-29's separate nuisance-based cap, which still applies to every pet owner.
Under § 21-29, keeping is a public nuisance if the lot's size, configuration, or facilities cannot adequately contain the animals or meet their spatial needs while also meeting the needs of the human occupants, or if neighbors face an unreasonable risk of dangerous contact, odor, or noise. A commercial kennel or pet shop is licensed separately: § 21-14 sets kennel fees at $10 a year for 10 or fewer dogs and $25 for more than 10, marking where the City treats animal-keeping as a business rather than ordinary pet ownership.
When the Health Officer believes a nuisance exists, § 21-30 requires written notice to the owner, tenant, or occupant and an administrative hearing where the person may contest the complaint and present evidence before any citation is issued.
Violations & Fines
A confirmed nuisance under § 21-29 lets the Health Officer reissue, modify, or withdraw the complaint after hearing; if the owner still will not comply, the Health Officer cites the owner for a violation. Section 21-31 punishes violations under Chapter 1, Article III's General Penalty, and a bird/animal-keeping license under § 21-26 can also be suspended when needed to abate the nuisance.
