Aside from RCV and ACV, a number of homes insurance policies also provide other coverage options for their customers. Insurance policies that cover building code violations or provide extended replacement costs, for example, are included in some homeowner's insurance policies. Building Code Coverage: Building code coverage pays for the work and supplies that are required to make your home compliant with local building codes and legislation. It is available through your homeowner's insurance policy. Home improvements are not covered by a standard homeowner's insurance policy. Building code coverage, on the other hand, may be able to reimburse you for the costs of certain improvements following a loss. Extended Replacement Cost Coverage (ERC): If you suffer a loss that exceeds the amount of coverage available for your dwelling, extended replacement cost coverage provides additional coverage.
