Allen-Sommer-Gage House
Also known as: Gage House

Why it's listed
Built in 1861 at 410 Normal Street in Chico, this wood-clapboard Greek Revival house was erected for R.H. Allen on a half-block bought from General John Bidwell, who had laid out the town the year before. The lumber was hauled by ox team from Nimshew. Doric columns mark the doorway and porch, and a balustraded second-story veranda opens through paired French doors. The nomination describes it as the oldest family residence of its size and quality in Chico, predating the Bidwell Mansion by at least four years. Allen, a teacher, opened a private school on the upper floor in 1862; it later served as the first public school in the new city district. C.J. Sommer, a jeweler and watchmaker, bought the house in 1880, and it has stayed in his family since, apart from rentals to two presidents of the Normal School. Interior remodeling, a bathroom, and later additions altered the house, but its facade and garden setting remain largely intact.
Significance in brief: The nomination presents it as the oldest family residence of its size and quality in Chico, predating the Bidwell Mansion by at least four years. It is also a rare Greek Revival example in an area where Italianate houses are more common. It is tied to early local education and to the Sommer family, prominent in Chico commerce and civic life.

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.
