The Short Version
The City of Costa Mesa has no breed-specific legislation restricting or banning any particular dog breed. California state law expressly preempts local breed-specific bans: Food and Agricultural Code Section 31683 prohibits any city or county from declaring a specific dog breed to be inherently dangerous or vicious. All dog regulation in Costa Mesa is entirely behavior-based, applying equally to every breed regardless of appearance or lineage. Animal control services in Costa Mesa are provided by Orange County Animal Care (OC Animal Care). Individual dogs that have demonstrated dangerous or aggressive behavior may be declared potentially dangerous or vicious through a formal investigation and hearing process, regardless of breed. Owners of such dogs must comply with heightened confinement, insurance, signage, and spay/neuter requirements. These designations are based solely on the individual animal's documented behavior, never on breed identity. One narrow exception exists under California Health and Safety Code Section 122331, which allows localities to adopt breed-specific mandatory spay/neuter ordinances. However, Costa Mesa has not enacted any such provision, and all breeds are treated identically under current city and county regulations. Private HOAs and landlords may impose their own breed restrictions through CC&Rs or lease agreements, but these are private contractual matters not governed by the state preemption.

What Happens If You Violate This?
There are no breed-specific penalties because Costa Mesa has no breed-specific ordinances, and California state law prohibits such measures. Owners of unlicensed dogs are subject to citation fines under OC Animal Care regulations, typically starting at $100. Owners of dogs declared potentially dangerous or vicious who fail to comply with imposed conditions — including secure confinement, liability insurance, posted signage, or mandatory spay/neuter — face escalating fines and potential impoundment of the animal. Administrative hearings determine the conditions and consequences on a case-by-case basis. Repeated or egregious non-compliance, or cases involving severe injury to a person, may result in an order for humane euthanasia of the animal and misdemeanor criminal charges against the owner under California Penal Code Section 399.
