Medico-Dental Building
Also known as: Centre City Building

Why it's listed
Rising fourteen stories at 233 A Street in San Diego, the Medico-Dental Building, also called the Centre City Building, was completed in 1927 to designs by local architect Frank W. Stevenson. Its reinforced concrete frame is clad in granite, brick, and terra cotta, with an L-shaped plan that brought light and air to every floor. Brick pilasters stress the vertical lines, while a heavily ornamented upper cap, arched windows, and a granite base give it a classical character. The building was conceived to gather the city's physicians, dentists, and a pharmacy under one roof, following a model already used in other American cities. Rentals were limited to medically approved tenants. Stevenson, who came to San Diego in 1920 to help plan the Naval Training Center, received a 1933 A.I.A. award for the design. The site earlier held Alonzo Horton's second home and later a school run by the Sisters of St. Joseph. After restoration, the building is used for professional offices.
Significance in brief: The nomination argues the building is an outstanding example of San Diego's early skyscrapers and the best representation of architect Frank W. Stevenson's work. It also reflects a planned concept of clustering medical and dental offices with a pharmacy in one location, and it earned a 1933 A.I.A. award. The site was also once home to Alonzo Horton's second residence.

What listing means for this property
For an income-producing building, listing (individually or as a contributing building in a district) is the gateway to the 20% federal rehabilitation tax credit on qualified rehabilitation costs, often stackable with state credits. Work claiming the credit must follow the Secretary of the Interior's Standards and be approved in advance.
Listing does not restrict a private owner acting without federal money or permits; where federal funding or licensing is involved, Section 106 review applies.
