Adam Carolla was born in Los Angeles County, California. His mother's maiden name was McCall. His parents separated when Adam was young. Carolla was not given a middle name by his parents; on his driver's license application he listed his middle name as "Lakers" as a joke.

On February 21, 2009, a day after his Los Angeles-based morning radio show was canceled -- as part of a format change at KLSX-FM -- CBS ordered a comedy pilot starring the actor/comedian. Ace in the Hole was to star Carolla as a husband and father who works as a driving instructor. Carolla created and wrote the pilot with Kevin Hench ("Jimmy Kimmel Live!"). Carolla stated that Pamela Adlon was to play his wife and Windell Middlebrooks of the Miller High Life commercial fame will play his best friend. During his March 30, 2009, podcast, Carolla briefly described the show as being "All in the Family, essentially", with Carolla playing a similar role to that of Archie Bunker. On the July 23, 2009, episode of the Adam Carolla Podcast, Carolla announced that CBS was not picking up the pilot for the 2009 season, "in any way, shape or form." On October 22, 2009, it was reported in Variety that Carolla had struck a deal with NBC to produce a half-hour pilot for a sitcom. The report was later confirmed on January 4, 2010, and was the first comedy pilot ordered by NBC for the season. The untitled project, written by Carolla and Kevin Hench, was a single-camera endeavor that starred Carolla as a contractor and father who attempts to rebuild his life after his wife leaves him. Carolla was set to executive produce the NBC project along with frequent collaborators Kimmel and Hench, as well as his agent James "Babydoll" Dixon, Jon Pollack from 30 Rock, Gail Berman, Daniel Kellison, and Lloyd Braun. Universal Media Studios, BermanBraun, and Carolla and Jimmy Kimmel's own Jackhole Industries. On the February 13, 2010 episode of Carolla's CarCast podcast, he broke the news that The History Channel had picked up Top Gear US, which NBC had decided against in 2008. On the March 26, 2010, episode of CarCast, Carolla said that he would not be co-hosting Top Gear US because of scheduling conflicts with his NBC sitcom project. In June 2010, Carolla said that his NBC pilot had not been picked up and was now "dead." Premiering on February 19, 2012, Carolla was also one of the contestants in the 12th season of NBC's The Celebrity Apprentice. He was fired in Week 4, because Trump perceived that Carolla did not utilize Andretti's car background during a Buick presentation, even though it was clear that Andretti did not like public speaking.
