Ask to see the engineering for those truss modifications.

Whether or not it did, or will, get by the city, those trusses *are not supposed to be modified* unless accompanied by engineering which states what to do where and how to do it.

Then, you will want to get a letter from the engineer which states 'yeppers, it was done as I showed it should be done'. That way, the engineer is taking all of the liability for saying 'It's okay.', not you.
