Full Breakdown
Under Union City Municipal Code § 8.40.010, keeping any household pets or other animals in a manner, number, or kind that causes damage or hazard to persons or property nearby, or that generates offensive noise, dust, or odor, is prohibited outright: regardless of how many animals are involved. There's no numeric threshold; the standard turns on the conditions the animals create. This sits apart from Chapter 8.22's separate two-dog permit cap and gives the City a nuisance-based tool to act on hoarding-type situations where sheer volume or neglect creates a hazard, odor, or disturbance for neighbors.
Violations & Fines
Violating owners face nuisance abatement action by the City: correction of conditions, removal or reduction of animals, and citation; repeated or severe cases can escalate to civil nuisance proceedings.
