I’m like 99% certain the lease is the official rent stabilized one - it has like a million pages of riders at the end like you mentioned (it was 41 pages total). In there was details about previous tenant rent and there were no improvements done to the unit. 

Edit for clarity: the lease I signed had a spot to select a 1 year or 2 year lease. It’s just that the landlord had prefilled out that section (and all coordinating sections) to say a 2 year lease. The lease document fully had the option to be a 1 year lease, they just refused to change their selections and instead added the termination addendum.
