Est. 1861 · San Francisco Landmark No. 17 · Surviving Fowler Octagon Plan · Colonial Dames Decorative Arts Museum · Only Octagon House in San Francisco Open to the Public
William C. McElroy purchased a lot on Gough Street near Union in the Cow Hollow neighborhood of San Francisco in 1859. McElroy worked as a wood miller in the rapidly growing city. Between 1860 and 1861 he built an eight-sided wood-frame residence for his family on the property, following the octagon-house plan popularized in 1848 by phrenologist and architectural writer Orson Squire Fowler.
The Fowler plan, set out in his book A Home For All, argued that an eight-sided house enclosed more square footage per linear foot of exterior wall than a rectangular plan, while also improving sunlight, ventilation, and family virtue. Several hundred octagon houses were built across the United States in the 1850s and 1860s. The McElroy Octagon House is one of three surviving in San Francisco and the only one open to the public.
The house remained in private use through the late 19th and early 20th centuries. By 1951 it had fallen into disrepair. The National Society of the Colonial Dames of America in California purchased the property, moved the building across Gough Street to its current location, and undertook a major restoration. The house opened as a museum in 1953.
The interior is furnished as a Colonial and Federal Periods Decorative Arts Museum. The collection includes American furniture, silver, paintings, and historical documents from the 1780s through the 1820s, with items by makers connected to the original thirteen colonies. A vault on the second floor holds documents signed by signers of the Declaration of Independence. The house is designated San Francisco Landmark No. 17.

Phantom footsteps
Unlike many of San Francisco's other Victorian-era survivors, the McElroy Octagon House has relatively thin paranormal documentation. The house's inclusion in regional ghost-tour literature derives more from its architectural unusualness — one of three surviving octagon houses in the city — than from any specific eyewitness tradition.
Docents at the museum have on occasion remarked to visitors that they sometimes hear footsteps on the upper floor when the house is otherwise empty, particularly during set-up before public openings. The Colonial Dames have not endorsed or promoted any paranormal interpretation of the house.
The 1951 relocation of the building across Gough Street is itself unusual in San Francisco preservation history. Moving the structure required jacking the wood-frame eight-sided building, transporting it across the street, and rebuilding the foundation. Some local accounts attribute the house's quiet atmosphere to this displacement, although that framing is speculative rather than evidentiary.
Visitors interested in San Francisco's haunted-house tradition will find richer accounts at sites such as the Westerfeld House, the Whittier Mansion, or the Mansions Hotel. The Octagon House is most valuable as a quiet, free, twice-monthly window into early-republic American decorative arts in a uniquely shaped Civil War-era frame.
