The Octagon House is a historic octagonal museum built in 1861 and operated by the National Society of The Colonial Dames of America in California, showcasing decorative arts from the American Colonial and Federal periods. Admission is free for all visitors, with donations appreciated. The museum is open on select days (second and fourth Sundays, February through November), and capacity is limited to 20 guests at one time. Street parking is available at metered spaces nearby, and a public garage is located approximately two and a half blocks west on Union Street at Laguna Street.
The building is a two-story historic structure with a carved curved staircase connecting the floors. As a small 19th-century wooden house museum, the original multi-floor layout — including an upper floor with wedge-shaped rooms — is an inherent feature of the property. Visitors requiring accessibility accommodations are encouraged to contact the museum directly at (415) 441-7512 prior to their visit.
Visitors note that the house is quite small and tours can be brief, with knowledgeable volunteer docents on hand. Some visitors mention that planning ahead is essential given the very limited opening hours and days. Street parking in the Cow Hollow neighborhood can be challenging to find.
