The county commission in each county, before each election, shall secure, for each voting precinct in the county, a suitable room or building in which to hold the election, and shall cause the same to be suitably provided with heat, drinking water and light and a sufficient number of booths or compartments, each containing a table, counter or shelf, and furnished with proper supplies for preparing ballots, at or in which voters may conveniently prepare their ballots, so that in the preparation thereof they may be secure from the observation of others. The number of such booths or compartments shall not be less than two. Such room or building shall be located in such precinct: Provided, That upon a determination of the county commission that a suitable room or building in which to hold the election is not reasonably available in such precinct then the county commission may secure a suitable room or building in which to hold the election for such precinct in an adjacent precinct in said county, in a location as near as may be to the territory of the precinct for which such room or building is provided. At any polling place for which parking spaces are available nearby, at least one parking space shall be reserved for handicapped voters and clearly designated as such.
