Is it a legal Triplex?

[Christian Valencia]

My wife and I are in the middle of purchasing our first "triplex". Including the air quotes because zoning hasn't given their final blessing that it's legally conforming. The property was constructed in 1880. It has 2 units in one structure and a cottage in the back. Unfortunately due to COVID, zoning can't provide an update until 40 - 60 business days, and our our closing date is 30 days from now. 

The Deed, Field Card, and Taxes show the property listed as a 3 family. Our attorney is saying that the Certificate of Zoning Compliance has the final word. 

Any advice on how to expedite the process? Will the appraiser pull permits to check if the cottage counts as a legal detached unit?
