City Council voted 11-4 to file the proposal after a bitter neighborhood split over preservation rules.
Supporters wanted stronger protection for early-20th-century homes; opponents argued the proposal lacked enough neighborhood support and would impose unwanted restrictions.
With 39 of 72 properties supporting the district, 26 opposed, and seven not responding, the political problem was clear. Preservation advocates say they expect the effort to return in another form.
The proposed Ansley Park historic district is now on indefinite hold after City Council voted to file the legislation.
