The SAISD school board paid $94,588.75 to buy "Spanish Acres," a 32-acre (13 ha) property, to develop the third high school in San Antonio. Construction began in the fall of 1930 and ended in January 1932. It was built for over $1.25 million.

In 1983 it became a part of the National Register of Historic Places. It was also designated a Texas historic landmark.

The school was designed by the company Adams and Adams. The entrance has two towers of different heights and is designed in the Baroque style. The towers are topped with silver. The school uses wrought-iron balconies and Spanish-tiled roofing. The school has two courtyards, both landscaped, bordered by portales. One courtyard has a hexagonal pond with decorative tiling. Hannibal and Eugene Pianta, an Italian immigrant and his son, decorated the main entrance columns and balconies with cast-stone ornamentation. Jay C. Henry, the author of Architecture in Texas: 1895-1945, stated that the architecture is similar to that of Lubbock High School.

In 1938 the school had an armory, a cafeteria, a drill ground, two gymnasiums, and a theater.

A music facility and the East Wing, a three-story addition, were built at a later time.

Its Moorish/Spanish architecture make it a visually distinct element in what was the old Woodlawn district.

In 1983 Jefferson was listed on the National Register of Historic Places. In 1995, it was included in the Local Historic District by the City of San Antonio. In 2010, Jefferson was selected as Grammy Signature Award Winner.
