Having experienced homelessness as a teenager, Warburton supports a number of charitable organizations assisting homeless and impoverished people. In 2009, The New York Times profiled Warburton and his volunteer work with Bottomless Closet, an organization that provides professional clothing, job readiness, and post-employment training and coaching services to women on assistance and working-poor women. Warburton gives style makeovers to women who are re-entering the workforce.
He produced the Real Fashion, Real Women runway show benefiting Bottomless Closet that closed the Fall/Winter 2011 New York Fashion Week and cast 24 women from the organization as models.

During the Fall/Winter 2011 New York Fashion Week, Warburton hosted a campaign for the nonprofit, It Gets Better Project, which aims to prevent suicide among LGBTQ youth. Warburton and other celebrities including Gabrielle Union, Miguel, Isaac Mizrahi, and Amanda Hearst filmed PSAs assuring LGBTQ youth that their lives would improve.
Since 2019, Warburton has volunteered with the Hollywood Food Coalition, preparing and serving food to the homeless in Los Angeles. Warburton is also involved with Rhonda’s Kiss, a charitable organization that assists patients with non-medical costs.
