Landowner is telling me that I have to "restore space" after I move out
I have a clinic lease.  Myself and the landowner have gotten along well since I started the lease 5 years ago.  My lease expires in 2 years.  I want to buy land and build my own office space because the current space is too small.  So I'm making plans to buy land and start the construction process.  I told the landowner I will be leaving when the lease terminates in 2 years.

When I first moved in, it was just an empty shell space and I spent about 200k on tenant improvements/buildout.

Landowner came up to me and insinuated that after I move out, I'm responsible for "clearing out improvements" to restore it to an empty shell space for the next tenant to build out as they want.

WTF?

I read the lease agreement and nowhere in there does it state this.

Is this a common thing?  I always assumed that when a tenant moves out, the new tenant has to pay for their own deconstruction/improvements of the space if they don't like the current layout.

Is this a real thing?
