Vacant foreclosed properties with mortgages backed by Fannie Mae and Freddie Mac are not subject to the City of Chicago’s registration ordinance, according to a recent ruling from the U.S. District Court for the Northern District of Illinois. The ordinance, which took effect in November 2011, requires mortgage lenders to register vacant properties with the city and pay a $500 registration fee. The ordinance also directs lenders to secure and maintain vacant buildings in accordance with city requirements.
