Report Shows Resilient Construction Offers Strong Investment Return

Report Shows Resilient Construction Offers Strong Investment Return

The return on investing in resilient construction of multifamily properties can be as high as 72%, according to a report by the Alabama Center for Insurance Information and Research at The University of Alabama.

The study measured the economic value of using FORTIFIED Multifamily, a voluntary beyond-code construction and re-roofing method developed by the Insurance Institute for Business & Home Safety.

The FORTIFIED Multifamily program was developed based on decades of lab and field research by IBHS to identify ways to strengthen homes, commercial buildings and multifamily properties against severe weather, including hurricanes and tornadoes.

“Our study found that resilient construction can provide an impressive return on investment, both in coastal and inland areas,” said Dr. Lars Powell, ACIIR director. “I think many people will be surprised not only by the low cost of the program but also by the substantial expected savings and revenues.”

Depending on the severe weather it will likely face given the region, a building can be constructed to a FORTIFIED standard for either hurricane or high wind, and property owners can choose from three designation levels, including roof, silver or gold. The FORTIFIED standard requires upgrades be verified and documented by an independent third-party evaluator. The standard is publicly available at no cost.

More than 40,000 homes in 22 states have earned a FORTIFIED Home designation, leading IBHS to expand the program to include a multifamily designation earlier this year.

“With more than 60 million Americans living in multifamily housing, our nation cannot meaningfully reduce the impact of natural disasters without building stronger multifamily communities,” said IBHS CEO Roy Wright. “Our research clearly demonstrates that a significant amount of storm damage can be avoided simply by investing in resilient construction, and this new study shows it’s financially beneficial to do so.”

The ACIIR study predicts lower insurance costs due to reduced risk, coupled with increased revenue, more than pay for the incremental cost of achieving a FORTIFIED designation. The size of this return on investment varied based on where the project was located and which FORTIFIED designation was sought, but ranged from 8.1% with added hail protection in inland areas to 72% for a gold designation near the coast.

According to the study, the requirements of the FORTIFIED standard increased construction costs between an estimated 0.29 and 1.43% of a building’s total cost, depending on the designation level sought and the property’s location. This added expense was more than offset by projected insurance savings and increased rent.

“We surveyed more than one thousand people from throughout the Southeast, and 74% of respondents indicated they are willing to pay higher rent to live in a resilient building,” Powell said.

Although the study found differences in the increased rent tenants in inland and coastal states were willing to pay, a similar percentage were willing to pay more regardless of where they lived. Some renters were willing to pay as much as 5% more in rent, while the average acceptable increase for those willing to pay more was 2.17%.

“Past research has demonstrated when high winds from severe weather events like hurricanes and tornadoes impact a FORTIFIED building, the resiliency will pay off in terms of reduced damage and loss of use,” said Fred Malik, managing director of the FORTIFIED program. “This study by The University of Alabama shows even before that happens, it literally pays to build resilient multifamily communities.”
