When people are forced to leave their homes due to a crisis, they often prefer the safety and comfort of staying with a host family over living in a camp or makeshift shelter. Hosting provides displaced individuals with a dignified, stable place to live, helping them recover and decide their next steps: integrate into the community, return home, or move to permanent housing.  The goal of this step-by-step guide is to offer a comprehensive framework for planning, designing, and implementing successful hosting assistance programs. It covers everything from vetting and matching hosts with guests to providing financial support and ensuring accommodations meet safety standards. The guide also includes practical examples and tools to help humanitarian organizations and volunteers deliver effective hosting assistance. You can find a summary of this guide in the Tip Sheet for Hosting Assistance Programming.
