Lassen County Court House

Why it's listed
Lassen County's court house in Susanville is a two-story reinforced concrete building, about 124 by 64 feet, built in 1917 and faced in gray sandstone quarried near the town. It sits at the center of a two-acre square and is organized around a Doric entry portico with flanking wings. Terra-cotta ornament appears on the entablature, cornice and belt course, including gargoyle faces, acanthus, Greek key and egg motifs. Inside, a two-story lobby has marble stairs with terra-cotta balusters, terrazzo floors and a wide ornamental ceiling molding. The second-floor courtroom is described as one of the most richly detailed and least altered historic rooms in California. Aluminum replacement windows, a changed entry landing and dropped office ceilings are the main alterations. The building is significant as an early twentieth-century Beaux Arts Classical Revival court house and as the county's only historic courthouse, and it still serves as one.
Significance in brief: The nomination presents it as a significant early 20th century Beaux Arts Classical Revival court house, with extensive terra-cotta ornamentation and a highly intact interior and courtroom. It is described as the only historic courthouse and the only substantial Classical Revival building in Lassen County. It was assessed for statewide significance but found to qualify at the local level.

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.
