A rare and special designation bestowed on the parish occurred in 1907, when the Vatican proclaimed St. Adalbert a basilica, the first in the USA.

[1] The St. Adalbert's Response to Love Center, run by Sister Mary Johnice, is located next to the Basilica and provides services for the poor of Buffalo, such as hot meals, a food pantry, toys and clothing for children, GED classes, and basic career-related computer training.

In 2016, St. Adalbert's former rectory was transformed into the Mother Teresa Home, a haven for pregnant women operated by the Diocesen Office of Pro-Life Activities.

In February 2008 the Vatican's highest Canonical Court upheld Bishop Edward Kmiec's decision to close the church.

St. Adalbert Basilica remains open to this day for four yearly special masses plus weddings, funerals, baptisms, tours, and other occasions.
