I work from home on a laptop. Do I need anything extra?
Often not. An employee working remotely on a company machine, with no clients visiting and no stock stored, usually sits inside what a homeowners policy tolerates. The question is worth asking once rather than assuming, because the answer changes quickly if any of those three change.
I run my own business from the house. Is that different?
Yes, and meaningfully. Business liability is excluded on a personal policy, and your equipment sits under a low cap. A home business endorsement or a small commercial policy fixes both, usually for less than people expect.
A delivery driver slipped on my path. Is that covered?
If the delivery was personal, generally yes under personal liability. If it was a delivery to your business, the carrier may treat it as a business exposure and decline. It is exactly the gray area that an endorsement removes.
