"Out Buildings"

[hpp4me]

I'm not sure this is the right label. I'm talking about a building in the back of a lot that we would use as a warehouse (although it might have to be presented in a different way to the County). It would be perhaps 800 square feet, built on slab. We'd like to have strong insulated walls, good roof, nice lighting and ventilation. It would essentially be like a shell of a house (open inside, no kitchen, no bathroom).

Can this be built in the county? Would would a house-quality building without the frill (just a shell, no plumbing) cost on a square foot basis to build?
