Coronavirus Emergency Non-Congregate Housing Expansion Act This bill makes non-congregate shelter expenses eligible for full funding reimbursement under the Federal Emergency Management Agency's (FEMA's) public assistance program during the COVID-19 (i.e., coronavirus disease 2019) public health emergency. Non-congregate shelter is defined as shelter for specified individuals who test positive for, have been exposed to, or are asymptomatic of, COVID-19, as well as first responders, health care workers, emergency workers, and homeless individuals who do not require hospitalization. Such shelter may be in the form of hotels, motels, dormitories, or any other spaces that permit social distancing. The federal share for non-congregate sheltering is increased to 100% (currently, FEMA only reimburses states, territories, and tribal governments for 75% of eligible costs incurred while performing emergency protective measures).
