Answer:
Read your governing documents to determine the coverage that should be available to you from the association's master policy.
Then, determine how much of your personal property you want to cover. Your personal coverage in a condominium is called an HO-6 policy, and may also include assessment protection in case of a disaster.
Ask your board to help you work through the kind of individual policy you need, and to educate you about coverage actually contained in the master policy.
