Reforming Disaster Recovery Act This bill addresses housing assistance in disaster recovery areas. The Department of Housing and Urban Development (HUD) must establish the Office of Disaster Recovery and Resilient Communities. The office's duties shall include (1) developing policy to build community resiliency and restore housing, (2) leading certain HUD disaster recovery activities, and (3) providing periodic disaster mitigation and recovery training to HUD staff. In addition, HUD must award grants under the Community Development Block Grant program for government entities to provide disaster relief, increase long-term resilience to natural hazards, and provide housing assistance to distressed areas after a declared major disaster. HUD and the Federal Emergency Management Agency (FEMA) must collect certain information during the course of a disaster recovery and make such information public. Additionally, the Government Accountability Office must analyze and report on the allocation of disaster-related housing benefits administered by FEMA, HUD, and the Department of Agriculture.
