Administration Buildings, historic buildings in Boca Raton, Florida, USA

The Administration Buildings are two two-story Mediterranean Revival structures designed by Addison Mizner in the mid-1920s, with a courtyard between them at 2 East Camino Real. They feature stucco walls, arched openings, and tile roofs. The buildings now serve as The Addison, an event venue, and were listed on the National Register of Historic Places on June 27, 1985.

Built in 1925, the structures were part of architect Addison Mizner's ambitious plan to create a Mediterranean-style resort city in Boca Raton during Florida's land boom of the 1920s. Though the grand resort vision was never fully realized after the boom ended, Mizner's influence shaped the architectural identity of South Florida for decades to come.

The buildings' name survives in their current use: since a later restoration they operate as The Addison, an event venue, and the courtyard between the two wings is used for ceremonies. The site is also tied to the Boca Raton Club, which lodged its staff in the structures from 1928 until 1983.

The buildings are located in Boca Raton's historic district and are easily accessible on foot when exploring downtown. You can view the architectural details from outside without entry fees, making them convenient to visit while walking through the neighborhood and observing other historic structures nearby.

The buildings' first tenant was Mizner's own Mizner Development Corporation, and land deals for thousands of acres were signed inside them. After the boom collapsed, the photographer who documented them for Florida Architecture of Addison Mizner in 1927 found them deserted. Visitors can still see the courtyard that links the two 1925 structures.
