LeConte Hall

Why it's listed
LeConte Hall is a three-story reinforced concrete building on the Berkeley campus of the University of California, finished in 1923/24 to designs by John Galen Howard. It was the first campus building built solely for the Department of Physics. Its cement-plaster exterior imitates classical stone, with Ionic columns, pediments, a red-tile hipped roof and a copper and glass skylight. It faces Gilman Hall across a small esplanade, in line with the Beaux Arts campus plan. Inside, classrooms, laboratories and offices line corridors behind two main entrances, with workshops in the basement. The building is listed for its science and education history. The cyclotron was invented there around 1929-30, Ernest Lawrence's Radiation Laboratory developed early in the 1930s, and work connected to the atomic bomb began in 1944. J. Robert Oppenheimer is also associated with it. The optometry program began there in 1923. Later additions and interior changes have left the east, north and south elevations nearly as built.
Significance in brief: The nomination argues the building is significant for its role in physics and education, including the invention of the cyclotron, the early Radiation Laboratory under Ernest Lawrence, and work tied to the atomic bomb. It is also tied to J. Robert Oppenheimer and to the origins of optometry at Berkeley. Architecturally, it is an important part of the Beaux Arts campus plan completed under John Galen Howard.

What listing means for this property
National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).
Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
