Disaster Savings and Resilient Construction Act of 201 8 This bill amends the Internal Revenue Code to allow a business-related tax credit for a specified portion of the cost of commercial and residential buildings that comply with resilient construction requirements in a federally-declared major disaster area. The bill defines "resilient construction requirements" as requirements that such buildings are designed and constructed to: (1) resist hazards brought on by a major disaster; (2) continue to provide their primary functions after a major disaster; (3) reduce the magnitude or duration of a disruptive event; and (4) have the absorptive capacity, adaptive capacity, and recoverability to withstand a potentially disruptive event. The credit does not apply to property for which a certificate of occupancy is issued after December 31, 2022.
