Abner Phelps House, Gothic Revival residence in Haight Ashbury, San Francisco, US

The Abner Phelps House at 1111 Oak Street, just west of Divisadero Street, is a two-story Gothic Revival building with Colonial features. It was assembled around 1850 from pre-constructed parts, and its address was formerly 329 Divisadero Street. It is not open to the public and houses a private business.

The building was constructed in 1850 and has relocated multiple times within the neighborhood, originally positioned on Divisadero Street. These relocations reflect the neighborhood's transformation during the city's rapid development in the decades following the Gold Rush.

Two accounts explain the house's origin. A 1934 version says John Middleton & Sons built it in 1850 from lumber cut into sections and shipped around Cape Horn from Maine, as San Francisco had no sawmills. In 1961 Phelps's great-granddaughter said it was built in New Orleans and reassembled here between 1850 and 1851 because Augusta Roussell was homesick for Louisiana.

The house at 1111 Oak Street, just west of Divisadero Street, is not open to the public; as of 2019 it houses a private business, so visits are limited to viewing the exterior from the street. The building has been moved three times, most recently in the 1970s to create a front yard, so its position on the lot differs from its original siting.

The house was built around 1850 on a 160-acre homestead that took in the land now occupied by the Golden Gate Park Panhandle. City limits only reached the property in 1854, so the house stood outside San Francisco when it was new.
