Ask a landlord-tenant lawyer and get answers ASAP
New York City.
My own research was is there are two routes when they file with the general attorney:
Non Eviction - we can keep renewing each year or two years our rent stabilized lease and when we no longer renew then they can convert our apartment to a Condo.
Eviction - we have to get 3 years notice.
They have not yet gotten authorization from the general attorney in NY to convert, but am wondering if there are any other situations such as above that would apply (as what I read seemed to apply from Rent Stabilization to Co-Op, not Condo). My worst nightmare is come my renewal in Feb they refuse to renew me.
