Except as provided in Code Section 44-5-60 and excluding covenants recorded on property solely by the property's owner, which shall run with the title to the land, a covenant runs with the land when, for consideration and as reflected in a duly recorded instrument found in the applicable chain of title, a property owner and a third party agree to such covenant, the property is adequately described in such covenant, and such covenant does not run for more than 20 years.
