(a) The description, location, and boundary of the Landmark site consists of the parcel
located at 651 Duncan Street, Assessor’s Parcel Block No. 6604, Lot No. 036, in San
Francisco’s Noe Valley neighborhood.

shown in the Landmark Designation Fact Sheet, as revised by the Historic Preservation
Commission at its February 17, 2021 hearing, and other supporting materials contained in

is eligible for local designation as it is associated with events that have made a significant
contribution to the broad patterns of San Francisco history and with persons significant to San
Francisco history. Specifically, designation of Lyon-Martin House is proper given association
with the history of development of homophile organizations in San Francisco, specifically the
Daughters of Bilitis, the first lesbian-rights organization in the United States, and as the
longtime home of pioneering lesbian-rights activists, Phyllis Lyon and Del Martin. The period
of significance is 1955 to 2020.
