Duplex: 1 structure, 2 deeds. Need 2 insurance policies?

[Megan Dwyer]

Buying a side-by-side duplex in Kansas. It is all one physical structure, but is 2 deeds. One unit's front door faces east, while the other front door faces south, so the two units have different street addresses. Given that it is all one physical structure (but there are two deeds), can I do just one landlord policy or do I need two? Getting very mixed answers from different insurance agents.
