How to find out if you can turn a separate garage into a rental

[Randall Re II]

My house is separate from my garage, and my garage is 750 sq ft. How can I go about finding out from the city/ or what do i do or who to call to find out if I can legally turn it into a livable space to rent out separately? My lot is over 7000 sq ft and my garage isn't to bad. Also, would it be expensive to turn the garage into a livable area? It's in Florida. I'd do a split unit in the garage because it's small or see how easily it is to add on to the A/C unit (its brand new). I'd have to add plumbing, etc. What do I need to do, so I can rent it out as Florida rental market is very good now.
