O.C.G.A. § 36-66C-4

A wireless provider may collocate small wireless facilities and install, modify, or replace associated poles or decorative poles under this chapter without an agreement with an authority and without an implementing ordinance. An authority may make available to wireless providers rates, fees, and other terms that comply with this chapter and that are adopted by ordinance, resolution, or another document by the authority after public notice. In the absence of an ordinance, a resolution, or another document that complies with this chapter, and until any such ordinance, a resolution, or other document is adopted, if at all, a wireless provider may collocate small wireless facilities and install, modify, or replace associated poles or decorative poles pursuant to the requirements of this chapter. An authority may not require a wireless provider to enter into an agreement to implement this chapter, but nothing in this chapter shall prohibit an authority and a wireless provider from voluntarily entering one or more such agreements, including such agreements with rates, fees, and other terms that differ from those in this chapter; provided, however, that the authority shall make each such agreement available for public inspection and available for adoption upon the same terms and conditions to any requesting wireless provider.
