Housing Victims of Major Disasters Act of 2018 This bill makes certain individuals and households eligible for housing assistance in connection with a major disaster, including Hurricane Maria of 2017. To be eligible, an individual or household must be: (1) occupying an otherwise unused or uninhabited property located in the area for which the major disaster was declared but does not have documented ownership rights to and is not renting the property, or (2) renting a property located in the area for which the major disaster was declared but does not have a written lease for the rental. The Federal Emergency Management Agency (FEMA) shall consider alternative forms of proof to determine the eligibility of an individual or household for assistance. FEMA shall enter into agreements with the Department of Housing and Urban Development to implement a Disaster Housing Assistance Program to provide temporary rental assistance to individuals and households displaced by any major disaster during 2017, and shall engage in consultations regarding the implementation of such program for future disasters.
