The determination was supported by substantial evidence. The record, including inferences and assessments of credibility, provides ample evidence that petitioners failed to meet the requirements of primary residency and/or family relationship for the right to succeed to the Mitchell-Lama apartment in question, in accordance with rules governing the rental of space in city-aided limited profit housing companies (28 RCNY 3-02 [n] [4]; [p] [3]; Matter of Shupack v. Dayton Towers Corp., 203 AD2d 134).
We have considered petitioners' remaining arguments and find them unavailing.
