(6) The tenant has unreasonably refused the landlord access to the housing accommodation for the purpose of making necessary repairs or improvements required by law or for the purpose of inspection or of showing the accommodation to a prospective purchaser, mortgagee or prospective mortgagee, or other person having a legitimate interest therein; provided, however, that in the latter event such refusal shall not be ground for removal or eviction if such inspection or showing of the accommodation is contrary to the provisions of the tenant's lease or other rental agreement.
(7) The eviction is sought by the owner of a dwelling unit or the shares allocated thereto where such dwelling unit is located in a structure owned as a cooperative or as a condominium and an offering prospectus for the conversion of such structure pursuant to an eviction plan shall have been submitted to the attorney general pursuant to section three hundred fifty-two-eeee of the general business law and accepted for filing by the attorney general, and been declared effective in accordance with such law, and any right of continued occupancy granted by such law to a non-purchasing tenant in occupancy of such dwelling unit shall have expired; provided that the owner of the dwelling unit or the shares allocated thereto seeks in good faith to recover possession of a dwelling unit for his or her own personal use and occupancy or for the use and occupancy of his or her immediate family.
