This document proposes solutions to homelessness in San Francisco. It discusses that homelessness is often caused by a lack of financial resources, as well as life events like relationship issues, job loss, illness, or substance abuse. San Francisco has spent $1.5 billion trying to end homelessness but still has thousands without shelter. The document advocates for a "No Homeless Left Behind" approach using scalable, affordable housing combined with supportive services. It suggests emulating programs in other cities that have housed over 100,000 people and exploring options like tenant housing and managed tent cities. Overcoming political and institutional challenges is seen as key to implementing more effective long-term solutions.
