National City, CA Animal Ordinances: Veterinary Clinic Zoning (2026)

Section 18.30.250 of the National City Land Use Code (Title 18) sets the ground rules for animal medical uses. The first restriction is on patients: veterinary clinics are limited to small, domesticated animals or household pets commonly maintained in residence with man. The Land Use Code glossary draws the line between the two facility types. A veterinary clinic is a treatment center serving only those small animals, while a veterinary hospital is an establishment where more than six domestic animals are kept for observation, diagnosis and medical care.

Both types are subject to a conditional use permit. In addition to whatever conditions the permit carries, four built-in requirements apply. The site must be located no closer than one hundred feet to any residential zone, or to any restaurant, hotel or motel. The operator must show that adequate measures and controls have been taken to prevent offensive noise and odor. Incineration of refuse or animal carcasses on the premises is not allowed. And the business cannot be operated as a kennel.

That last rule matters because the glossary defines a kennel as any place where three or more dogs are kept for breeding purposes and the pups are sold, or where dogs are received for care or for boarding by the day, week or month, or longer. A veterinary practice that adds boarding as a business line moves toward that definition and out of what § 18.30.250 authorizes. The section also sits inside the specific-use chapter, Chapter 18.30, whose purpose clause says that where it conflicts with the zone chapters, the specific-use standards control.

Applicants should expect the planning process for a conditional use permit under the permits and applications chapter of the Land Use Code, and the noise and odor showing is a condition of the permit itself rather than a separate later filing. Because the one hundred foot measure runs to any residential zone and to restaurants, hotels and motels, a site next to a Mile of Cars dealership is treated no differently from one on a retail strip: the distance test is applied to the neighbors named in the section.
