The provision of your homeowners policy that covers business pursuits is applicable only when your main office is away from your home and you take work home. For example, a notary public working from a professional office, also can meet with clients at his home office (on weekends, or after hours). Other than that, your homeowners policy won’t cover business related claims. It may in some instances provide coverage for “sleep and fall” accidents and business personal property, but frankly, you must have a stand alone business insurance.
Insurance coverage for your business will depend on your operations and other specifics.
If you are an importer of consumer goods you would need a product liability insurance, if you are a contractor – general liability insurance, and so on. Your business insurance agent should be able to suggest correct coverage.
