As a rental building, the landlord insures virtually all risk for Orchard House at the expense of lessees, so some (and oftentimes their tenants) don’t carry their own insurance… which I do not recommend. Like any homeowner or tenant you’ll want protection for your possible liability for damage to your property and that of others, and for personal injury/death in which you or your guests might play a role.
Beyond liability, a policy should cover the value of suite upgrades, such as to flooring or appliances, your possessions, and live-out expenses, should an incident or damage make your suite or the entire building uninhabitable for some time. The retail cost for a policy should be about $200.
