Disaster Savings and Resilient Construction Act of 2021 This bill allows a tax credit through 2023 for certain residential or commercial buildings owned by a taxpayer in a disaster area that are designed and constructed to meet resilient construction requirements. The bill defines resilient construction requirements as requirements with respect to buildings in a disaster area that make such buildings resistant to hazards brought on by a major disaster, reduce the magnitude or duration of a disruptive event, and have the capacity to withstand a potentially disruptive event.
