The present station building, completed in 1998 is a hashigami (橋上) structure where passenger facilities are located on a bridge which spans the tracks.

The bridge also connects to a second station entrance from road on the south side of the tracks, where there is a roundabout and parking lots for cars.

A JR Travel Centre (Warp Plaza) is located on level 1 of the station building.

Shido Station was opened on 1 August 1925 as the terminus of the Kōtoku Line was extended eastwards from Takamatsu.
