Summary

Fairfax County allows veterinary hospitals only where the Zoning Ordinance permits them by right or special exception, and every one needs Health Department sign-off before a building permit issues. Outdoor components trigger a special exception in most commercial and industrial zones, and rural-zoned hospitals need a full acre.

These county ordinances apply to unincorporated areas of Fairfax County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Standards applicable to all veterinary hospitals: (1) The construction and operation of all facilities must be approved by the Health Department before any building permit or Nonresidential Use Permit is issued. (2) The emission of odor and noise must be mitigated through the provision of ventilation and soundproofing in accordance with all County and State standards. Standards when permitted by right: (3) In the C-3, C-4, and PCC Districts, a veterinary hospital must be located within a completely enclosed building. (4) In the C-5, C-6, C-7, C-8, I-3, I-4, I-5, and I-6 Districts, a veterinary hospital must be located within a completely enclosed building. If any portion of the building or facilities include outdoor components, the use is allowed only by special exception in accordance with subsection 8100.3. Standards when permitted by special exception: (5) In the R-A, R-C, R-E, and R-1 Districts, the minimum lot size is one acre. If co-located with an animal boarding, breeding, or recreation establishment that has outdoor facilities, the minimum lot size for both uses combined is two acres.

Full Breakdown

C sets the operating standards for every veterinary hospital in the county. Before the county issues a building permit or a Nonresidential Use Permit, the Health Department must approve the facility's construction and operation. Odor and noise from kennels, exam rooms and treatment areas must be mitigated with ventilation and soundproofing that meets both county and state standards, a requirement enforced through the same permit review. Where a veterinary hospital is a by-right use, the rules tighten by district: in the C-3, C-4 and PCC commercial districts the entire hospital must sit inside a completely enclosed building, with no outdoor runs or pens.

3, which means a public hearing before the Board of Zoning Appeals or Board of Supervisors rather than an administrative permit. In the rural and low-density residential districts, R-A, R-C, R-E and R-1, a veterinary hospital is allowed only by special exception and needs a minimum one-acre lot. If the hospital is co-located with an animal boarding, breeding or recreation establishment that itself has outdoor facilities, the combined minimum lot size for both uses jumps to two acres. 2, a figure site plan reviewers check against the proposed building footprint before any use permit is finalized.

Violations & Fines

A veterinary hospital that opens or expands without the required Health Department approval, without the applicable special exception, or with outdoor facilities in a district that requires enclosure is operating in violation of the Zoning Ordinance. The county can withhold or revoke the building permit or Nonresidential Use Permit, and zoning enforcement can pursue the use as a zoning ordinance violation subject to civil penalties and a compliance order to cease the noncompliant activity until the property meets the district standard or obtains the required special exception.

Frequently Asked Questions

Can I open a veterinary hospital in a Fairfax County commercial district without a special exception?
Only if it's fully enclosed. In the C-3, C-4 and PCC districts, and in C-5 through C-8 and I-3 through I-6, a veterinary hospital is by-right when the entire operation, including any outdoor runs, is inside a completely enclosed building. Any outdoor component in the C-5 to I-6 group requires a special exception.
How much land does a veterinary hospital need in a rural Fairfax County zone?
In the R-A, R-C, R-E and R-1 districts a veterinary hospital is allowed only by special exception and requires a minimum one-acre lot. That minimum rises to two combined acres if the hospital is co-located with an animal boarding, breeding or recreation establishment that has outdoor facilities.
Does the Fairfax County Health Department review veterinary hospitals before they open?
Yes. Zoning Ordinance § 4102.5.C requires Health Department approval of the facility's construction and operation before the county will issue a building permit or Nonresidential Use Permit, in addition to the zoning district standards.
