Palm Beach Property Appraiser info inaccurate!

[Al Banfe]

I just bought a triplex. The property appraiser shows its a triplex! I found out today when checking with zoning (about adding parking) that the garage (that was turned into an apartment) was never permitted. 

Zoning has the property listed as a duplex.

Zoning said its possible that if code enforcement receives a complaint, we could be fined $500 per day for unpermitted rental.

We bought this mid Febuary based upon it being a triplex...do I have any recourse?
