Building a single structure to be considered two separate, individual buildings can be tough to do. The structure has to be such that either one can burn and fall away without harming the other building. Every building system gets involved and not just at the attachment point. For example, are there two separate fire alarm systems? This structure is also L shaped, right? All the required building separation distance rules come into play at the inside right angle juncture. Any windows planned there? Are the exterior walls there up to snuff? You might be required, or forced even, to handle that problem yourself. Do the construction plans for this building not include a code sheet that explicitly explains how the project is defined? It is the building code that dictates how many buildings there are.
