in 1805, and was elevated to university status by the Maryland General Assembly the following year. To accommodate the prospering school, DuBourg oversaw the construction of several new buildings. Among these was St. Mary's Seminary Chapel, referred to by Elizabeth Ann Seton as "Mr. DuBourg's chapel." DuBourg hired Maximilian Godefroy to design the chapel, who he had previously appointed to the faculty of St. Mary's. Work began in 1806, and DuBourg expedited the project by retaining Benjamin Henry Latrobe, the Architect of the Capitol, whose skilled Italian artists completed the building ini 1808. Diocesan ministry DuBourg ministered to and provided charity to the many refugees living in Baltimore who had fled Saint-Domingue during the Haitian Revolution. With John Tessier, he also established a congregation for the many poor Black Baltimoreans who met and celebrated Mass at St. Mary's Chapel. From this congregation eventually formed the Oblate Sisters of Providence. DuBourg also established a lay fraternal organization of parishioners that provided charity for the city. DuBourg played an important role in the construction of Baltimore's first cathedral. Bishop Carroll desired to replace St. Peter's Pro-Cathedral with a proper cathedral, and DuBourg convinced him to move it from St. Peter's to a new location. DuBourg identified a site atop a hill, which would become known as Cathedral Hill, and negotiated with the sale with the owner of the land. He then raised the $23,000 necessary to purchase the land, . Construction on the cathedral began in 1806.

Seton opened her school in June 1808, where women from around the country joined her. DuBourg was influential in the founding of her religious community. He contributed $8,000 to establish her religious community, and proposed that she adopt the rule of the French Sisters of Charity. Heeding this proposal, she established a community of the Sisters of Charity on 31 July 1809, in Emmitsburg, Maryland. While Seton was the head of the organization, DuBourg functioned as their ecclesiastical superior. Before long, tensions arose between Seton and DuBourg, who forbade her from communicating with her mentor, a Sulpician priest, Pierre Babade. Seton appealed DuBourg's instruction to John Carroll, who referred
