Joe Biden was Vice President under President Obama from 2008-2016. He served as a Senator from Delaware from 1972-1978. He is best known for his push to enact the Violence Against Women Act, support of anti-gun violence measures and efforts to address climate change. He does not have a specific affordable housing plan, but supports efforts to open up affordable housing opportunities for those with criminal records.
Biden's campaign supports ensuring housing opportunities for people with criminal histories. The Biden Plan for Strengthening America's Commitment to Justice even suggests that HUD only approve contracts with entities that will provide a "second chance" to those with criminal histories who need affordable housing and social services.
