This concerns landlord changing my apt #, which is “4A” (not really) to 04A.
All my registrations going back many years show apt 4A. Landlord purchased building 2014. 2015 dhcr registration shows “04A” as do 2016 and 2017. 2018 registration reverts back to “4A” and then the entire annual registration history for my apt disappears. “Reg not found” from 1984 thru 2018.
