Discrepancy between building dept and tax dept

[Megan Brooks]

Has anyone had an issue where there is a discrepancy between the building dept and tax dept in town? 1 is saying my house is 3 units and then other is saying 2 units. Building department has no documentation to back this statement up except a CO that was issued to us at the closing stating it is 2 units by them. Tax department has record of tax card stating its 3 units. Any input? Were you able to get it resolved without attorneys and a lot of money?
