The office was activated on June 1, 1978 and was first known as the Philippine Constabulary/Integrated National Police Regional Command 1 (PC/INP Recom 1) originally stationed at Camp Bado Dangwa, La Trinidad, Benguet.

It originally covered part of the Cordilleras and the Ilocos provinces. The activation of the PC/INP Cordillera Command on April 1, 1989 paved the way for the Regional Command to transfer its office at Camp Diego Silang, Carlatan, San Fernando City, La Union with only four (4) provinces left under its jurisdiction namely: Pangasinan, La Union, Ilocos Sur and Ilocos Norte. It subsequently acquired its permanent site at Parian, San Fernando City, La union on July 29, 1989 and it was named Camp Brigadier General Oscar M Florendo on May 2, 1991 in honor of the late Brigadier General Oscar M Florendo, an outstanding Military Officer from La Union.
