Dear Brooklyn Tenant:
Your issues are driven by the terms of a unique lease, and so, you should seek an attorney to review the lease and your landlord's demands.
You may be entitled to compensation for an alteration to the premises prior to the end of the lease. Generally, a landlord is entitled to access to the premises for making repairs or improvements, but not demolition during the course of the tenancy. A trespass arises when the landlord enters the premises, for an impermissible purpose, and without the tenant's consent. Your landlord is operation under a tight schedule and so may be eager for your cooperation.
Of course, the lease may anticipate this event, and your rights may not be greater than the rights you negotiated when you started the tenancy.
Generally, a tenant is entitled to the premises, as is, through the duration of the lease, subject to repairs from time to time, to maintain habitability.
The answer provided to you is in the nature of general information. The general proposition being that you should try to avoid a bad outcome if you can.
Your lease will control. The landlord sounds like he is acting reasonably. However, you have the right to the same fixtures until the day you leave. Which fixtures? And, will 2 weeks really make a difference in your life? I mean will it be worth litigating? Move out 2 weeks early and sue for prorated rent?
I may be guessing or not licensed in your state. No atty/client relationship exists.
