The board of health and welfare shall have the power, and it shall be its duty to promulgate appropriate rules necessary to implement and enforce the following standards for licensing private foster homes pursuant to this chapter. Such rules shall:
(1) Require evidence of income and resources sufficient to maintain the home and the services offered.
(2) Require such recordkeeping and reporting regarding children’s status and progress as may be deemed necessary.
(3) Assure the safety and adequate physical care of children under care.
(4) Require that foster parents be physically and emotionally suited to care for unrelated children and to deal with problems presented by children away from their own homes and own parents and shall require a criminal background check.
Provided, however, nothing in this chapter shall be construed to cover the occasional or irregular care of a neighbor’s, relative’s or friend’s child or children by a person not ordinarily engaged in child care.
