Full Breakdown
Under the City of Rockville Zoning Ordinance, a Veterinary Service (a facility staffed by at least one state-licensed veterinarian) must operate entirely indoors except for outdoor runs. Those runs must be fully enclosed by a fence at least six feet high and, outside the I-L zone, set back at least 100 feet from any lot line. In the R-400 and R-200 residential zones the use is conditional and additionally requires a minimum one-acre lot, with any structure for overnight animal keeping set 50 feet from any off-site residential use. This is City of Rockville land-use law, not Montgomery County's; Rockville administers its own Zoning Ordinance inside city limits.
Violations & Fines
An unfenced or under-setback outdoor run, or a vet clinic sited on an undersized lot in R-400/R-200 without conditional-use approval, is a zoning violation subject to enforcement under the Ordinance.
