The Homeless Emergency Assistance and Rapid Transition to Housing Act of 2009 (HEARTH Act) amended the McKinney-Vento Homeless Assistance Act, revising the Emergency Shelter Grants Program in significant ways and renaming it the Emergency Solutions Grants (ESG) program.

The ESG Interim Rule took effect on January 4, 2012. The second allocation of FY 2011 ESG funding and future years are all subject to the ESG regulations. See the HUD ESG quick reference Guide for more details.

In 2020 Johnson County, KS applied to Kansas Housing Resources Corporation (KHRC) on behalf of sub-recipients for 2020 HUD ESG-CV funding.
