A building under construction is not covered under a standard building insurance policy or a home insurance policy since it is not a complete structure. As a contractor, you may be responsible for unique loss exposures related to buildings under construction such as the theft of building materials and high valued equipment such as generators and compressors.

Builders risk and installation insurance provides coverage for homes or buildings while undergoing construction, until they are completed. The policy covers the contractors’ interest in materials at the job site before they are installed, construction materials in transit designated for the contractors' equipment insurance–a policy specially and the value of the property being constructed until it is completed.
