After the restoration of Taiwan to Chinese rule, the building changed its name to the Taipei County Peitou Guest House. Its pool was used as a communal bath, and the county set up an entertainment hall called the Chungshantang. The upstairs was even used as the Kuangming Police Station. Later the KMT turned the entertainment hall into their Peitou Party headquarters.
台灣光復以後，此屋改名為台北縣議會北投招待所，游泳池成為大澡堂，並設有娛樂廳「中山堂」；後來國民黨將「中山堂」改為北投區黨部，光明派出所也搬入樓上。
