We are a collection agency wanting to file a mechanics lien on a piece of property in Iowa on behalf of our client for monies due for lease of a 20' storage container. The piece of property is listed in Iowa as a single family dwelling. However, the lessee is a business who's address (billing & mailing) is that single family dwelling property. The property owner is a Trust in the name of the business owner. Could this be considered a commercial Iowa Lein or must it be filed as a residential lien due to the status of the property listing?
