Renter who made an intransic apartment change

In the event that a tenant made changes to the apartment illegally; changes that are not protected by the provisions of self-repair as stated in section 7 of the Rent Law, the landlord, as stated in section 20A (b) of the Rent Law, require the tenant to restore the status quo.
In extreme cases of building a structure or planting seedlings other provisions apply.

The tenant’s obligation to return the apartment to its original condition does not give him any discount regarding the return of the apartment to the landlord on time at the end of the rental period, as stated in section 20 (a) of the Rent Law.
Moreover, for making those changes, the landlord may demand payment from him on the part of ‘making wealth and not in law’.
