For starters, the slab will never be considered good for a 'living space'...... no vapor barrier, not enough steel.Better to have a contractor come in and make sure the electrical is ok and then leave it at that.You could go down to the city building department and ask vaguely about converting a garage and see what they say.

Wrong concrete PSI, wrong steel pattern, no vapor barrier, etc.....we usually had to tear down and build new.

Water vapor condensation should be kept outside an interior wall by the Kraft paper on the insulation. 

This included fiberglass insulation, new drywall, new vapor barrier.

Are you going to install some type of vapor / smell barrier as well.

Washington's capital gains tax would be less than similar levies in Idaho, Oregon and California, Inslee said.He also said a proposed levy on carbon polluters would raise $380 million and a 50-cent per pack tax on cigarettes, along with a separate tax on e-cigarettes and vapor products, would raise an additional $56 million.Inslee's plan would also repeal tax breaks on royalties and for oil refineries, limit sales tax exemption to $10,000 on trade-in value of used cars, and impose a tax on the sale of bottled water to consumers.Inslee said Washington still faces an "enormous budget challenge" because revenues aren't keeping up with projected expenses, especially in light of the McCleary state Supreme Court decision mandating more education funding."

If you heat lead paint over 1100 degrees with a heat gun, the vapors can cause your brain to swell.

There is more to consider than the average person may understand....especially in Florida where the greatest part of the load on an AC system may actually be humidity (water vapor must be condensed out of the air before the air can be cooled below the dew point).For what it's worth...David J Dachtera

A talented mold ASSESSOR might visit and not only give an estimate but also provide helpful hints where the performance of the structure is concerned as it relates to vapor activity.
