Irvine, CA Animal Ordinances: Breed Restrictions (2026)

Under Sec. 4-5-802, an animal becomes "potentially dangerous" if, unprovoked, it requires a defensive action to prevent injury, bites causing a less-severe injury, or attacks another animal off its owner's property. Sec. 4-5-803 escalates the finding to "vicious" for animals that inflict severe injury or death on a person or animal, or that keep offending after a dangerous designation. An animal services officer investigates complaints and reports findings to the Director of Public Safety (Sec. 4-5-809); if probable cause exists, a hearing officer holds an administrative hearing within five to ten working days (Sec.

4-5-811). Owners found in violation can be ordered to microchip or tattoo the animal, muzzle it in public, use a leash no more than three feet long, carry a bond or liability insurance, enroll the animal in approved behavioral training, or keep it in a secure enclosure (Sec. 4-5-809). Vicious animals may be banned from the City or humanely destroyed if the owner won't comply, fails to reclaim an impounded animal within 30 days, or if release would threaten public safety (Sec. 4-5-815). Separately, the Director may bar a person found responsible for a vicious animal from owning any animal in Irvine for up to three years (Sec.

4-5-816). Owners have 15 days after a determination to file a written appeal with the Director of Public Safety, who assigns a different officer to hold a new, de novo hearing (Sec. 4-5-812). The City adds a special fee to the offending animal's registration once a declaration is finalized (Sec. 4-5-817).
