If there was no MCI filed for my rent-stabilized apartment for "improvements" my landlord stated he made 4 years ago (right before I moved in), is the rent increase based on the improvements still legal? Can he go back a file a retroactive MCI?
As well, if he did file, when can he start charging the higher rent, isn't it when DHCR approves the MCI increase? So if he files in September 1998, and DHCR approves in December 1998, he can't charge the higher rate until December 1998?
