Larkin House, Historic adobe house in Monterey, California, US

The Larkin House is a two-story wood-frame building at the southwest corner of Calle Principal and Jefferson Street, with whitewashed adobe walls and a low-pitch hip roof. A two-story flat-roof veranda covers three of its four sides, sheltering the adobe façade. Inside, the post-and-beam framing is exposed, and there is a fireplace and chimney.

Thomas O. Larkin, a Massachusetts native who went into business with his half-brother John B. R. Cooper in California in 1832, built the house in 1835. Local sawmills could not supply enough redwood, so he framed it in New England fashion and finished the walls in whitewashed adobe. It is believed to be California's first two-story house and the first with a chimney, and it served as the only United States consulate in Monterey, then capital of Alta California. It was named a California Historical Landmark in 1933 and a National Historic Landmark in 1960.

Larkin wanted a New England-style house, but local sawmills could not supply enough redwood, so he built a wooden frame and finished the walls in whitewashed adobe. The covered second-floor porch protected the adobe from rain. The house shares its parcel with the Sherman Quarters, and its entrance is in the gardens.

The house stands at the southwest corner of Calle Principal and Jefferson Street, and its entrance is in the Larkin House gardens. It shares its parcel with the Sherman Quarters, a stone building tied to U.S. military history. The property is a featured part of Monterey State Historic Park.

The house shares its parcel with the Sherman Quarters, a stone building whose entrance, per William T. Sherman's memoirs, lay in the Larkin House gardens; he called it "the adobe back of Larkin's."
