The General Assembly intends that: all children whose care is the responsibility of the State shall have similar protection for their health, their safety, and the quality of their care; and the regulations of State units that are charged with child care shall be comparable. The Department shall adopt regulations: to carry out §§ 9–235 and 9–236 of this subtitle; and that require each juvenile care facility to: establish and implement a safety plan for the safety of juveniles under the care of the facility; or implement a safety or emergency plan established for the facility for another purpose; and revise the safety plan not less than every 5 years. A child care home or child care institution may not be required to obtain a license from more than one State unit. A State unit authorized to license child care homes or child care institutions may make a cooperative licensing arrangement with another State unit.
