Welcome to Elmore County

Elmore County was established February 7, 1889, with its county seat at Rocky Bar. It is named after the Ida Elmore mines, the area’s greatest silver and gold producer of the 1860s, located near Silver City in Owyhee County.

A station on the overland stage route, originally named Rattlesnake, was moved west to the railroad line and became Mountain Home. On February 4, 1891, the county seat was moved to Mountain Home.

Elmore County offices will have reduced hours and closures over the holiday season.  All County offices will be closed on the following dates: November 22nd (in observance of Thanksgiving) December 25th & January 1st (in observance of Christmas and New Years) All County offices (with the exception of District Court) will be closing at 10:00 a.m. on both December 24th & December 31st.
