Iowa Code § 562B.26: Failure to maintain by tenant.

If there is noncompliance by the tenant with section 562B.18 materially affecting health and safety that can be remedied by repair, replacement of a damaged item, or cleaning and the tenant fails to comply as promptly as conditions require in case of emergency or within fourteen days after written notice by the landlord specifying the breach and requesting that the tenant remedy it within that period of time, the landlord may enter the mobile home space, and cause the work to be done in a skillful manner. The landlord may submit an itemized bill for the actual and reasonable cost or the fair and reasonable value thereof as additional rent on the next date when periodic rent is due, or if the rental agreement was terminated, for immediate payment.
