A childcare license specifies a capacity — the most children allowed in care at once. For centers, capacity is usually set based on available floor space (at least 35 square feet of usable indoor space per child is a common baseline, though the exact figure varies by state), fire-code occupancy, and sometimes by the number of licensed staff on duty. For family child care homes, capacity is set by a combination of square footage, the number of infants allowed, and staff-to-child ratios. Exceeding licensed capacity is a violation that can result in corrective action or license suspension. See /data/fcc-capacity-by-state for family home limits and /data/ratios-by-state for how ratio rules interact with group size.
