A. Unless otherwise agreed, use by the tenant of the dwelling unit for any purpose other than as his place of abode shall constitute a breach of the rental agreement and shall be grounds for terminating the rental agreement.

B. If the tenant wrongfully quits and abandons the dwelling unit during the term of the tenancy, the landlord shall make reasonable efforts to make the dwelling unit available for rental. If the landlord rents the dwelling unit for a term beginning before the expiration of the rental agreement, said rental agreement terminates as of the commencement date of the new tenancy. If the landlord fails to use reasonable efforts to make the dwelling unit available for rental or if the landlord accepts the abandonment as a surrender, the rental agreement is deemed to be terminated by the landlord as of the date the landlord has notice of the abandonment. If, after making reasonable efforts to make the dwelling unit available for rental after the abandonment, the landlord fails to rerent the premises for a fair rental during the term, the tenant shall be liable for the entire rent or the difference in rental, whichever may be appropriate, for the remainder of the term. If the tenancy is from month-to-month or week-to-week, the term of the rental agreement for this purpose is deemed to be a month or a week, as the case may be.
