Medico-Dental Building, Office skyscraper in downtown San Diego, United States

The Medico-Dental Building is a 14-story reinforced concrete tower at 233 A Street, on the southwest corner of 3rd Avenue and A Street in downtown San Diego. Its L-shaped plan has two wings fronting A Street and 3rd Avenue, with concrete walls faced in quarried granite on the lowest three stories and brick above. The neoclassical revival facade carries ornamental cast iron trim and rosette-style windows, and the gabled rooftop is finished with Spanish tile. Inside are a marble lobby floor and staircase beneath a restored coffered ceiling.

The structure was built in 1927 on the former site of Alonzo Horton's second residence and was the tallest building in the city at that time. The land had previously housed the Academy of Our Lady of Peace, which was established by the Sisters of St. Joseph.

The name reflects its original purpose: clustering licensed physicians and dentists in one building, with a ground-floor pharmacy and a medical library on the 14th floor. A Board of Directors and Officers enforced the rule that tenants be licensed doctors or dentists. The 1933 A.I.A. award for Commercial/Industrial work went to the building and its architect, Frank W. Stevenson.

The building stands at 233 A Street, on the southwest corner of 3rd Avenue and A Street, a short walk from other downtown San Diego landmarks. It is a working office building with ground-floor retail space, so the lobby and upper floors are not open for sightseeing. Look up from the street for the gabled Spanish-tile roof and rosette-style windows.

The Sisters of St. Joseph bought the corner lot from Alonzo Horton in the 1880s and ran the Academy of Our Lady of Peace there, using Horton's carriage house as a convent and offices. The school stayed until 1925, when it moved to Normal Heights and the Horton buildings were razed for the tower.
