The FORTIFIED Multifamily™ Wind program includes a re-roofing and construction standard and verification process that mitigates wind-peril losses for multifamily structures. In this study, we estimate the net value of the FORTIFIED™ Multifamily Wind program by comparing the marginal costs to the marginal benefits. We present the analysis in relation to the owners of buildings because they are the ultimate decision makers. However, we note that value can accrue to owners through increased value to tenants (higher rent) or government (reduced disaster cost).
