Spurred by recent reports that a convicted sex offender was working as a super in an Upper West Side brownstone -- and pressuring tenants for sexual favors -- Assemblyman Micah Kellner and Senator Charles Schumer proposed legislation Sunday to prevent a repeat.

The bills would prohibit convicted sex offenders from becoming a super or manager in any multifamily apartment building in New York or nationwide, unless they disclose their past.

"Building workers know more about our lives than most of your friends and families," Kellner said. "They know your schedule, they know your kids' names. And when they knock on your door, you let them in because you trust them. You never think that possibly on the other side of that door is a truly dangerous sexual predator who has done just vile and disgusting things."

"The fact that these offenders have access to apartments where children are present is scary," Schumer said. "And that's why the legislation that Assemblyman Kellner is doing and the legislation that I am doing should close this all too large loophole."

The legislation would require a sex offender to disclose his or her conviction and obtain the signed consent of the building owner before possessing keys to a residence.
