(1) If the lessee fails to return the leased residential space upon termination of the lease, then the lessor may claim further damages within the meaning of section 546a (2) only if the return failed to occur for reasons for which the lessee is responsible. Damage is to be compensated only to the extent that equity demands indemnification. This does not apply if the lessee has given notice of termination.
(2) If the lessee is granted a period of time before vacating the premises under section 721 or section 794a of the Code of Civil Procedure (Zivilprozessordnung), then they are not liable for compensation for further damage until the end of the period of time.
(3) A deviating agreement to the disadvantage of the lessee is ineffective.
