Summary

Union City bans keeping any household pets or animals, in whatever number, that cause damage or hazard to neighboring property or generate offensive noise, dust, or odor: no fixed head count, just a nuisance-based standard.

The keeping of maintenance of any household pets or pets or any other kind of animal or animals in such manner, number, or kinds as to cause damage or hazard to persons or property in the vicinity or to generate offensive noise, dust or odor, shall not be permitted.

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.

Frequently Asked Questions

Is there a maximum number of pets allowed in Union City?
No fixed citywide cap under this section, but keeping enough animals to cause damage, hazard, noise, dust, or odor is a nuisance regardless of number. A separate rule in Chapter 8.22 requires a permit for more than two dogs.
Who enforces this against a suspected hoarding situation?
Union City's Animal Control, under the City Manager's office, investigates complaints and can pursue nuisance abatement action under Chapter 8.40 against owners whose animals cause hazard, damage, noise, dust, or odor problems.
