Answer: The US Department of Education has provided guidance on this term: “In determining whether a child or youth is living in “substandard housing,” an LEA may consider whether the setting in which the family, child, or youth is living lacks one of the fundamental utilities such as water, electricity, or heat; is infested with vermin or mold; lacks a basic functional part, such as a working kitchen or a working toilet; or may present unreasonable dangers to adults, children, or persons with disabilities. Each city, county, or State may have its own housing codes that further define the kind of housing that may be deemed substandard.” USED Guidance, March 2017, A-3.
