There's a reason why landlord policies are more expensive then regular homeowners policies, they present more risk. Normally detached structures on your property are covered under coverage B in your HO3 and I would check to see what this portion of the policy is costing you opposed to the liability. Like DJ said the liability part of a policy is usually not very expensive. I actually like that they separated the liability here you should feel more adequately covered.
