Four years ago Manhattan District Attorney Alvin Bragg set aside a group of about a dozen lawyers to prosecute housing fraud cases across the city. The office’s Housing & Tenant Protection unit has since brought forward 10 cases, including against heavy hitters Meyer and Joseph Chetrit, brothers and former owners of high-profile properties like the Chelsea Hotel and Chicago’s Willis Tower, for allegedly harassing elderly tenants in Chelsea. The unit has also brought forward cases involving deed theft, rental scams and other alleged abuses of New York’s real estate laws. Earlier this month the office secured guilty pleas from three developers in Brooklyn accused of cheating 421-a, the once-popular but now-expired state program that granted generous incentives to developers who built affordable housing. Bragg recently spoke with Crain’s about his office’s quest to bring bad actors in the real estate community to justice.
