The shop building on a property I want to buy was built in 2005 but not wired until 2006. The building is metal with a wood framed interior office and bathroom.
It appears to be wired with Romex and has been carefully structured with the outlets at the 5' high purlin. All of the other runs are taken up to the 10' or higher to go across and appear to be captured with clamps or plastic ties to the metal structure and protected by the material similar to running down a wood post, etc. The load balance appears to be ok, with separate circuits for the items that require them, etc.
On the area above the office, the wires are stapled to the floor along the steel wall, but the floor is storage area.
Is this an acceptable situation for an outbuilding of this type? Does it matter whether or not the proposed use of the building is as a shop, or for storage, or for animals or a combination thereof?
I am wondering what would be necessary to fix it if it is not ok for some identified use. For example, could the romex be rerun in plastic conduit or raceways anything like that to make it acceptable if it is not ok as is.
Update: I am so sorry I left this info off - this is an outbuilding on an acreage with a separate house with attached garage, not commercial. This building is a playroom/shop/horse stable/whatever building. I don't know exactly how it will be used yet. I expect that the building is not to code, but I don't know. It looks like someone tried pretty hard to get it right. No one seems to know who did the work, nor how many owners ago. The building has water, electrical 125 amp service panel tied to the main house (outside of the house not in its panel. There is a breaker in the panel for the house and another for this special use building, both served by the same meter although separate meters could be installed easily. The building has a concrete foundation with water and sewer plumbing installed in the floor. It is not insulated except the office and bathroom 20 x 8 is insulated, heated with space heater and air conditioned. It also has a water heater (small)).
