For your convenience and guidance, we have included a resource document from the National Alliance to End Homelessness called "Changes in the HUD Definition of Homeless."
A link can be found to the right of this blog under Definitions Related to Eligibility.
This is an extremely helpful guide that delineates specifically how homelessness is defined: 4 categories, eligibility for permanent supportive housing, etc. On pages 3-6 there are tables contrasting the former and new definitions. Furthermore, the tables include a column detailing the required documentation to substantiate homelessness (chronic or otherwise.)
Please take the time to familiarize yourselves with this resource.
