Illegal dwelling unit in Massachusetts?

[Jochy Perez]

Hi,

Got into quite a bit of a mess and hoping you can help or point me in the right direction. The building inspector needed to stop by to do a walkthrough which was done.  It's a 2 Family but on the 3rd floor the previous owner had an illegal apartment.  The 3rd floor is vacant currently and was going through renovation.  There's no kitchen but the existing plumbing was left behind where the kitchen used to be.  He's going to be sending me a letter stating I have an illegal unit although there's no kitchen and the floor is empty. He wants me to tie the 2nd floor and the 3rd floor together building a wall.  Not sure what I can do in this case.  He said because I bought the house, I inherited the problem. My intentions were to go through the process of getting a special permit to make it into a 3 family but due to the high cost it was not worth it.

I'm assuming there's a fine involved.
