You will need two separate policies to protect your investment:
Your own insurance policy.
This provides coverage for your personal possessions, structural improvements to your apartment and additional living expenses if you are the victim of fire, theft or other disaster listed in your policy. You also get liability protection.
A “master policy” provided by the condo/co-op board.
This covers the common areas you share with others in your building like the roof, basement, elevator, boiler and walkways for both liability and physical damage.
Also ask your insurance professional about the following additional coverages:
This reimburses you for your share of an assessment charged to all unit owners as a result of a covered loss. For instance, if there is a fire in the lobby, all the unit owners are charged the cost of repairing the loss.
This insures your property for damage by the back-up of sewers or drains. Water back-up may not always be included in a policy. Check to see that it is included.
This is an inexpensive way to get more liability protection and broader coverage than is included in a standard condo/co-op policy.
Flood or earthquake
If you live in an area prone to these disasters, you will need to purchase separate flood and earthquake policies. Flood insurance is available through FEMA’s National Flood Insurance Program. Both flood and earthquake insurance can be purchased through your insurance agent.
Floater or endorsement
If you own expensive jewelry, furs or collectibles, you might consider getting additional coverage since there is generally a $1,000 to $2,000 limit for theft of jewelry on a standard policy.
