In the event that an individual who qualifies as a bona fide CCOO vacates his/her condo/co-op unit and offers it for rental, said unit is decontrolled solely for the purpose of establishing the initial rent subsequent to the bona fide CCOO vacating. The new base rent shall be established at the amount charged in the initial lease subsequent to the bona fide CCOO vacating. This new base rent shall be documented by submission and filing of a completed rent registration form and fee to the Rent Leveling Office. Said unit is decontrolled for the purpose of establishing the initial rental only and otherwise is fully subject to Chapter
155. Nothing herein shall be construed to cause an existing rent to change as a result of any initial rental decontrol granted under this section.
