Abandoned property, Iowa law

[Barb Asay]

I am wondering if anyone can point me to the document or source that dictates how a tenants personal property is to be handled after an eviction or abandonment in the state of Iowa.  

I have read the Landlord Tenant law section from the state website but other than a confusing section about bailment on page 14 I cannot seem to find the law on this subject.  

My lease currently states, as I’ve seen others so in our area, that abandoned personal property will be stored for 30 days and than disposed of at landlords discretion.  But I’m wanting to know if that’s even required.
