Is this suspicious? Apartment w/commercial lease

Where is the unit? Is it a ground floor on a narrow street? Does it look like it used to be a retail space?Maybe the commercial use is non-conforming but is grandfathered which requires continued use and if there is a vacancy, then the vacancy cannot last longer than two years. Otherwise the space reverts to the conforming use. A commercial lease could be used to substantiate the continued non-conforming use.

it happens, but (while I'm not an attorney, and this isn't legal advice) I'd be worried about insurance. you sign a commercial lease, you move in, there's a fire ... who pays for your burned stuff?

I did this many years ago in Calif. The utility rates wound up being much higher because the space was not considered residential.
