Loring House

Why it's listed
Built in 1914 at 1730 Spruce Street in Berkeley, this stucco-clad, two-story house with a basement was designed by architect John Hudson Thomas for Ernest L. Loring, a dentist who had served on the Berkeley Board of Education. Its cross-shaped plan, widely projecting roof that appears to float above a ribbon of casement windows, and simple rectangular corner piers mark it as Prairie School work. Geometric wood panels reflect Viennese Secessionist ideas, while the interior of white plaster and natural redwood follows Bay Tradition practice. The nomination calls it the earliest and truest Prairie School house in Berkeley and a highly representative example of Thomas, whose output ranged across many styles in the 1910s. It resembles published Frank Lloyd Wright designs without copying them. The house has changed little apart from a basement apartment, a partly remodeled kitchen, and repainted trim. Only the original lot is included in the nominated property.
Significance in brief: The nomination argues the house embodies the distinctive characteristics of a period of construction and is the earliest and truest example of Prairie School architecture in Berkeley. It is also a representative work of John Hudson Thomas, a master architect of the Bay Tradition. It retains a high degree of integrity.

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.
