Georgia Code Title 21. Elections § 21-2-367

(b)(1) In each precinct in which optical scanning voting systems are used in a state-wide general election, the county election superintendent shall provide at least one voting booth or enclosure for each 250 electors therein, or fraction thereof.

(2) For any other primary, election, or runoff, the county or municipal election superintendent may provide a greater or lesser number of voting booths or enclosures if, after a thorough consideration of the type of election, expected turnout, the number of electors who have already voted by advance voting or absentee ballot, and other relevant factors that inform the appropriate amount of equipment needed, such superintendent determines that a different amount of equipment is needed or sufficient. Such determination shall be subject to the provisions of Code Section 21-2-263.
