TV Line reports that the Smallville actor has been asked to appear in all seven episodes of the show's first season.
Breaking In stars Christian Slater as Oz, the head of a team of counter-security experts.
Rosenbaum appears in the pilot as Dutch, the boyfriend of Odette Yustman's character Melanie, but producers were said to be so impressed with his performance that they decided to develop his character further.
Dutch and Melanie are expected to be involved in a love triangle with one of the team's new recruits, played by Bret Harrison.
Breaking In premieres on April 6 at 9.30/8.30c on Fox.
