Can brokers in NYC and management companies in NYC operate out of the same apartment building with the same phone number?

It's not unusual for New York management companies to wear two hats, that of managing agent of the property and that of broker. Managing companies frequently augment their management fees, which tend to be modest, with broker commissions. In fact, management companies expect and depend on this income and view it as part of their compensation package. Fees are charged to the New York City tenant if the apartment is leased and to the owner if the New York apartment is sold. As long as the management company is properly licensed as a broker by the New York Secretary of State, the arrangement is entirely legal.
