Legality of showing occupied apartment

[machpo]

My landlord is attempting to sell my building (4 units). His real estate broker has been showing the building (and the 2 empty apts in it). Am i required to let the broker show my apartment?
thanks.

basically yes. most leases state that the owner has the right to show the property. many states have laws in place that require the LL to give 24 hours notice, but there is no such law in new york. but they are supposed to give 'reasonable' notice so as not to inconvience the tenant too much.
