Full Breakdown
Under County Code § 26-28-230, a veterinary clinic is defined as an office and indoor facility providing medical treatment to animals, covering large and small animal veterinary clinics, animal hospitals, incidental retail sales of pharmaceuticals for animal health care, and onsite kenneling of animals. The use-standards table applies one district-specific restriction: in the RRD (Resources and Rural Development) and AR (Agricultural Resources) zoning districts, a veterinary clinic may treat farm animals and livestock only, it cannot serve companion animals such as dogs and cats, or exotic pets. Outside those two districts the standard use definition governs without that limitation.
Violations & Fines
Operating a clinic that treats companion or exotic animals in an RRD or AR zoned parcel exceeds the permitted use standard and is a zoning code violation subject to code enforcement by Permit Sonoma.
