North Star House, Historic mansion in Grass Valley, United States

North Star House is a residence in Grass Valley built in the early 1900s featuring California Arts and Crafts design with exposed beams and natural materials throughout. The structure occupies substantial grounds that include heritage orchard trees and open space for various activities.

James Hague, president of the North Star Mine, commissioned Julia Morgan in 1904 to design the 11,000-square-foot house; it was her first major commission after she received her California license in March 1904. It housed mine superintendent Arthur DeWint Foote and his wife, author Mary Hallock Foote, and was meant to impress Eastern investors. The Foote family bought the house in 1929 and lived there until 1968.

Mary Hallock Foote wrote two novels in her office at North Star House after the birth of four granddaughters. The Valley Road, which had five reprintings and became a bestseller, urged young women to attend college and have a career before marrying. Ground-Swell was one of the first novels about lesbians. Critics puzzled over these "western women" with voices and opinions.

The house stands at 12075 Old Auburn Road, near the Nevada County Fairgrounds, on a 14-acre hillside site overlooking foothills and valley. It now serves as an event and cultural center; restoration began with the roof after 2002 and continues, with the first floor nearly finished and second-floor work begun in 2025. The Heritage Garden is the highlight of the landscape restoration.

After the Foote family sold it in 1968, a preacher called Rev. Bill ran a boarding school for at-risk youth here and altered the house; rumours about the school earned it the local name Devils' Mansion. The school failed and closed, and Rev. Bill was not heard of again.
