What is the average cost per square foot for building a warehouse in Maine?

It depends on where you are purchasing the warehouse. In more rural areas such as northern Maine (like Aroostook county) or western Maine (in areas not consumed with winter tourism like Sugarloaf) you will pay a far cheaper price than in the southern and eastern areas of the state. Factors like whether or not you are looking in a metropolitan area like Portland, Lewiston-Auburn or Augusta will also play a role in determining the cost. Any reputable Realtor will be able to give you ideas on specific regions and square footage costs for the types of real estate you are considering. If you don't yet have a Realtor, the mls website can also be a helpful resource.
