Ventura County, CA Animal Ordinances: Veterinary Clinic Zoning (2026)

Ordinance Code Section 8107-10 sets one hard rule for veterinary clinics on unincorporated land: the clinic building itself must be completely enclosed and soundproof. The section carves out exactly one exception, cross-referencing Section 8107-21, which governs temporary pet vaccination clinics run out of a trailer or portable structure rather than a permanent building. Section 8107-21 attaches real limits to that exception. A temporary clinic can operate no more than one day in any 90-day period within a one-mile radius of a previously conducted temporary clinic, so a provider cannot rotate the same neighborhood every week.

The clinic may provide only preventive care: it is barred from diagnosing or treating an injured, sick or diseased animal except to the extent immunization or vaccination itself requires it. Every vaccination has to be given inside the trailer or portable structure, never in the open, and the clinic can operate only during daylight hours. It also cannot block a public right-of-way or parking aisle without a permit, and all related materials and facilities must be cleared from the site the day the clinic departs.

For a permanent operation, the county's Article 5 use tables classify veterinary clinics serving pet animals as a discretionary use needing a Conditional Use Permit or a Planned Development permit depending on the zone before the Planning Division will approve one on unincorporated land; veterinary hospitals for large animals draw the same CUP-level review. 7's Table of Parking Space Requirements fixes off-street parking at one space per 200 square feet of gross floor area, plus long-term bicycle parking of one space per 25 employees and short-term bicycle spaces equal to 2 percent of the required motor vehicle spaces.

None of this reaches Oxnard, Thousand Oaks, Simi Valley, Ventura, Camarillo, Moorpark, Santa Paula, Fillmore, Port Hueneme or Ojai: each incorporated city licenses and zones veterinary uses under its own separate code.
