A Puerto Rican maintenance man says the Brooklyn real-estate firm that manages Starrett City held him back solely because he was not a paesan.

“No employee who was not Italian or of Italian descent would become a superintendent,” Edwin Marquez says bosses told him at the East New York apartment complex managed by Grenadier Realty.

His Brooklyn federal court suit says supervisors Orlando Palmetti and Vincent Oppedisano would fault Latinos’ work and say, “Italians would’ve done a better job.”

Grenadier did not return a call for comment.
