Mortgage question on mixed-used property

[Suzanne Emily Nguyen]

In the process of selling a property that is a 6 units mixed-used building.  5 residential units & 1 commercial space. 

1 of the unit is zoned commercial with outsourcing dry cleaners. Is it necessary that the banks are asking for floor plans of the space? I've given them the jacket of the property with all permits/leases/info of property history. 

First time being involved with commercial sale.
