Lala Har Dyal, first Secretary General of the Association and editor of Urdu Gadar Journal, Kartar Singh Sarabha, editor of the Punjabi edition and other volunteers responsible for the printing and mailing of the weekly Gadar Journal and other publications, lived and worked in the building. Over a period of time, the building became known as “Gadar Ashram”.

India became independent, Gadar building was handed over to the Indian Consulate in San Francisco in 1949. The building was in a dilapidated condition and was not fit for use. A suitable memorial, a two storey new building, with US$ 83,000 from Government of India and rest raised from the Indian community in California, was built and named Gadar Memorial Hall. Sardar Swaran Singh, the then Minister of External Affairs, performed the ground breaking ceremony in September 1974. India's Ambassador T.N.Kaul, performed the inauguration ceremony for the new building in March 1975. Gadar Hall is currently used by the Consul General of India for celebrating national festivals like Independence Day and Republic Day and for other official functions.

The Gadar Memorial Hall is now the living symbol of the glorious sacrifices of the Gadarites who, in the words of former President K.R. Narayanan, “faced untold misery and hardships in pursuit of their objective and even made the supreme sacrifice of laying down their lives.”
