Rotchev House, Russian colonial residence in Fort Ross, United States.

The Rotchev House is a single-story building at Fort Ross State Historic Park in Sonoma County, California, built in 1812. It measures about 36 by 48 feet and is made of hand-squared redwood timbers joined by notches at the corners. Its steep hip roof is laid in split and hewn redwood planks up to 23 feet long and 1 inch thick, chiseled in place to channel water away from the gaps. Inside are seven chambers and a larger hall.

Built in 1812, the house is one of the buildings raised in Fort Ross's first year by the Russian-American Company team under Ivan Kuskov. It is named for Alexander Rotchev, the settlement's last Russian commander, who lived there with his family. After the company sold the fort to John Sutter in 1841 and left in 1842, William Benitz added a second floor for his large family; Ada Fairfax and the Call family later occupied it, and it served as a hotel into the early 20th century.

The house takes its name from Alexander Rotchev, the last Russian commander at Fort Ross, who lived here with his family. After the Russians left in 1842, it served as a home to William Benitz, who added a second floor for his large family, then briefly to James Dixon, and in 1869 to Ada Fairfax and her household. The Call family kept their base here until early 1878, and the building later operated as a hotel into the early 20th century.

The seven chambers and main hall are open for visitors to explore within Fort Ross State Historic Park. The setting allows you to walk around the wider compound and understand how the Russian colonial settlement was laid out.

It is the only surviving original structure built by Russian hands within the Fort Ross compound, as all other buildings were reconstructed later. This makes it a rare example of authentic Russian construction methods on the northern California coast.
