California’s 2026 Fair Rules Change Some Equine Event Requirements

Published: September 13, 2026  ·  Status: 2026 event rules

California’s 2026 rules for state-supported fairs continue equine health controls and adjust parts of the Equine Medication Monitoring Program for qualifying low-fee public horse shows.

What changed

The rules bar EIA-positive or non-negative reactor horses from entering, residing, competing, or selling at state-supported fairgrounds. They also describe the medication-monitoring program and a 2026 exemption for certain public horse shows meeting specified low entry-fee thresholds.

Why equine operations should care

Boarding barns that host, haul to, or prepare horses for state-supported fair events should make sure their event files match the current year’s rules.

What operators should do now

• Verify event-specific EIA and health requirements before hauling.
• Confirm whether medication-monitoring fees apply to the event.
• Keep medication and treatment records organized for competition horses.
• Avoid relying on last year’s fair packet when preparing 2026 entries.

Keep written barn procedures, horse records, transport documents, and client communications aligned with the rules that actually apply to your operation. For related documentation, review the horse boarding contracts guide, Barn Setup, and the MyStableForms state package library.
