Following the Texas Revolution, Olivarri became a landowner and wagon train manager in San Antonio. Texas General Land Office records show that he received a certificate for one-third of a league of land in February 1838. Olivarri was married twice. His first wife, Juana Padillo y Olivarri, was born in 1816 in Bexar County and died around December 1862. She left her estate to her natural son born of a previous marriage. After her death, Placido Olivarri married Micaela Jimenes (or Ximenes), who was born in June 1844 and lived until 1917. Together, they had fourteen children.
Late in his life, Olivarri was a member of the Sociedad Mutualista Mexicana. He was listed in San Antonio city directories in the 1880s and into the early 1890s as a “ranchman.” The San Antonio Daily Express on May 2, 1892, listed a Placido Olivarri (possibly Olivarri himself or his son) as chairman of his voting precinct. Olivarri lived in San Antonio throughout his life, and died on September 8, 1894. He was buried in the San Fernando Cemetery No. 1. The Texas Centennial Commission erected a Centennial marker at his grave in 1936.
