You can protect your property before you even complete construction.
Coverage varies by policy, but usually includes damage caused by events such as fire and hail storms. You’ll also normally be covered for theft and vandalism (though not by your employees) and damage caused by vehicles or aircraft hitting the building. To make sure coverage levels are adequate, policies are often set at a fixed percentage of the total construction budget. You’ll need to check how long the policy runs as it typically won’t allow repeated extensions of the construction timeline.
