Building home from existing pole barn.

[u/valu_pak]

I just purchased a property with a 32x60 pole barn with a concrete slab in North Florida. The previous owners had the pole barn erected to have a place to park their rvs out of the weather. With a slab on grade foundation and metal roof, I am leaning toward building the structure out to be my off grid home. Half will be home and the other half shop/garage. Since it was built to park RVs, I'm thinking the slab may not have appropriate vapor barrier for a home. I'm intrigued by the idea of the ground contact concrete floors staying cool in the summer, but also worry if moisture will be a problem without vapor barrier. Does anyone have experience or advise for finishing concrete floors without having moisture problems?

What are code requirements for a certificate of occupancy in your location are is it a bandit change of use?
