Can they kick me out of my apartment?

Depends on the co-op rules but there are many co-ops that either don't allow apartments to be rented out or require board approval.

Co-op could move to evict you, your only recourse would be to seek damages against the unit owner who improperly leased to you.

The wheels of justice move very slowly in New York city and are very pro tenant. Even if the co op board finds out you are renting improperly it would take a long time for them to get you out. Housing courts are always inclined to give occupants more time to move.

In other words they won't throw you out on your ass for at least 6 months. But if you end of going to court mostly every landlord and their mother will know you've fought it in court so try to resolve this with the owner and the board so everyone is happy.

even spunky's right sometimes.

zizzi-thanks for the left handed compliment coming from that means a lot to me.

Sit back and relax, the coop board has no right to go after the tenant but the unit owner. Most boards would not bother since the board would have to buy out the share of the unit at the market value in order to establish pro bono.

"in order to establish pro bono" Huh? Pro bono usually refers to legal services provided free of charge. Not sure what you mean inoeverything.

this guy 'inoeverything' and his sidekick 'inquirer' have been posting nonsensical items for the past week or so. my guess is he's under house arrest and has nothing better to do. A certainty is that he's not too bright.

Bottom line:
The eviction process takes a long time.
It probably won't come to that.
You shouldn't let it come to that since it hurts your credit.

Isn't it somewhat known that coops severly restrict the duration of how long you can rent?

However, you might want to start looking around at other options so you don't get surprised.
