Full Breakdown
The City of Rockville Zoning Ordinance defines a Child Care Center as a facility providing licensed child day care (excluding in-home Child Care Homes) and requires it to satisfy all applicable State and Montgomery County licensing requirements. On top of that, City land-use rules mandate that outdoor activity areas be enclosed by a fence or barrier at least four feet high to ensure occupant safety and prevent unauthorized entry or exit, and that any outdoor play area be safely reachable without crossing a hazardous area such as a street or driveway. In the R-400, R-200, R-150, R-90, R-75, R-60, R-40, and RMD-Infill residential zones the use is conditional and subject to a minimum-lot-area table scaled to enrollment, starting at 7,000 sq. ft. for 9-12 children up to 30,000 sq. ft. plus 500 sq. ft. per child over 40. This is a City of Rockville zoning standard, layered on top of separate State/County child care licensing.
Violations & Fines
An unfenced outdoor play area, one under four feet, or one requiring children to cross a street or driveway to reach it is a zoning violation; operating in a residential zone below the enrollment-scaled minimum lot area without conditional-use approval is also a violation.
