Homan got his first acting role on an episode of the CBS series L.A. Doctors. From there, he was cast on a new CBS sitcom Yes, Dear in 2000, beginning with the show's third episode until the series ended in 2006, playing the role of Dominic Hughes, the eldest child of Jimmy (Mike O'Malley) and Christine Hughes (Liza Snyder). Despite being a child actor, he was credited as part of the main cast, unlike the other children in the series. In 2003, he was cast in The Italian Job, the 2003 remake of the original film, playing the younger version of Mark Wahlberg's character Charlie Croker.
In 2006, he was nominated for the award for the Best Performance in a TV series - Supporting Young Actor (Comedy) at the 27th Young Artist Awards for his performance on Yes, Dear, which was won by Angus T. Jones.
