Florida State Law in 1948 required new school buildings be placed on lots not less than ten acres in size. As the existing lot was not large enough, a property search began and the present day site on Mill Street was chosen. A $50,000 school was erected during the winter and summers of 1948 and 1949. In 1950, an auditorium was completed. At that time the school enrollment was 365. In 1964, a Music Suite was added.

In 1967, Baldwin became the first Duval County School to be integrated. In April 1975, Community Education came to Baldwin under the direction of Mr. Michael Minton.

In 1984, Baldwin added a new Media Center, Guidance Suite, and a classroom wing that today houses the sixth grade. In 1990-91, the school added a new Gymnasium. A Cafeteria, Band and Choral Suite, Graphic Arts Suite, and five additional classrooms were made from the old Gymnasium.

In the fall of 1993, lights were installed on Baldwin's Baseball Field and were operational for the 1994 season. The addition of a new Football Stadium also began in 1994. That project was completed in time for the first football game in August. Since then, improvements to the field area have included a new rubberized track, field event areas, a scoreboard, and fencing.

In 1999, the school was completely rewired to help us immerge into the 21st Century. This wiring was for network and communications, linking all of our classrooms together and to the world via the Internet. While our student population is smaller than most of the secondary schools in Duval County, we strive to offer a variety of courses here at Baldwin.
