Builder's risk insurance (Contractor's All Risk insurance – CAR insurance) is a special type of property insurance which indemnifies against damage to buildings while they are under construction. Builder's risk insurance is "coverage that protects a person's or organization's insurable interest in materials, fixtures and/or equipment being used in the construction or renovation of a building or structure should those items sustain physical loss or damage from a covered cause." Necessity Buildings are subject to many different risks while under construction. They may catch fire, be damaged by high winds, or fall victim to other force majeure. A principle of common law is that any new construction or other improvement to land becomes property of the owner of the land – the title holder – once there has been an "improvement" to the owner's site.

If you are going to properly setup your policy, coverage should be effective prior to when the materials are delivered to the job site. Coverage ends upon the earlier of closing of the sale, occupancy or the policy expiration date. After builder risk coverage expires, due to sale or occupancy, the new owner should take out permanent property insurance on the building such as a home owner's policy or a commercial property policy. Insurance costs generally run between one and four percent of the construction cost, depending upon the type of insurance purchased and exclusions from coverage. Purchasers Coverage can be purchased by the property owner or general contractor. Builder's risk coverage may be necessary to show proof of insurance to comply with local city, county, and state building codes and is often required as a condition to many contracts. Many architects believe that it is the property owner who should have the builder's risk policy, because they have already paid for the improvements to their land,
