The Federal Housing Finance Agency and the city of Chicago have reached a face-saving settlement in a longstanding legal dispute over whether Fannie and Freddie, as entities under federal conservatorship, are subject to the city’s vacant-building ordinance. Under the terms of a settlement reached earlier this month but announced last week, the two GSEs will voluntarily register vacant properties with the city but won’t be subject to a $500 registration fee. The FHFA will also no longer seek to recover registration fees or penalties already paid to Chicago.
