San Leandro Breed Restrictions Rules (2026): What You Need to Know

The City of San Leandro's municipal code contains no provisions targeting specific dog breeds for prohibition or heightened regulation. This is consistent with California state law: Food and Agricultural Code Section 31683 explicitly prohibits any city or county from enacting or enforcing an ordinance that declares a specific dog breed — or dogs of any specific breed — to be dangerous or vicious. The preemption prevents San Leandro from instituting a pit bull ban, a Rottweiler restriction, or any similar breed-specific measure that singles out dogs based solely on breed characteristics rather than individual behavior.

Animal control services within San Leandro are provided under contract by Alameda County Animal Services, headquartered at the shelter facility in Hayward. The behavioral framework follows California Food and Agricultural Code Sections 31601 through 31683. A dog may be declared potentially dangerous if, on two or more separate occasions within a 36-month period, it has bitten, attacked, or caused physical injury to a person or domestic animal without provocation while off the owner's property, or if it has approached a person in a menacing manner while unprovoked and not confined. A dog may be declared vicious if it has killed or caused severe injury to a person without provocation, or if it was previously declared potentially dangerous and the owner failed to comply with all conditions imposed. These determinations follow a formal investigation and, upon the owner's request, an administrative hearing before a designated hearing officer. The evaluation applies uniformly to all dogs regardless of breed, size, or appearance.

San Leandro is a diverse East Bay city of approximately 92,000 residents with a mix of single-family neighborhoods, multi-family housing, and commercial areas. Dog ownership is common throughout the city, and the behavior-based approach ensures that responsible owners of any breed are treated equally under the law. Owners of dogs declared potentially dangerous or vicious must house the animal in an escape-proof locked enclosure when not under the direct physical control of a responsible adult, post conspicuous warning signs at all property entry points, have the animal spayed or neutered within a specified period, and maintain a minimum of $100,000 in liability insurance covering bodily injury and property damage. Homeowners' associations and landlords within San Leandro may impose their own private breed restrictions through CC&Rs or lease agreements, but these are private contractual restrictions and are not government ordinances — they are not preempted by state law.
