Buying a home with a setback violation?

[Braulio Espinosa]

Hey all,

I am currently in the hunt for my first deal in Miami and plan to house hack. I found what a home where the numbers would work for me, however there is a setback violation. Pretty much the previous owners added a laundry room (with permits) that is 2 feet from the fence when it has to be at least 5 feet away. The house has had this violation for 20 years and the current owner has never received a fine or citation.  Was wondering if anyone had any experience buying a house with this violation/ if it is even possible to do with conventional financing? 

Thanks!
