In this section, “respite care” means care that is made available for an individual with an intellectual disability in a State residential center to provide relief for the person with whom the individual ordinarily lives. Under regulations that the Department adopts, each State residential center shall reserve at least 2 percent, but not more than 4 percent, of its total beds for respite care. Respite care for an individual may not exceed 45 days within any 1–year period or 28 consecutive days.
