As Florida and the Southeast begin recovering from 2024’s destructive hurricanes, many people are asking: How can we rebuild sustainably and in a way that avoids the same damage, costs and trauma in future storms?

There are proven ways to strengthen homes that pay off in the long run, such as installing hurricane straps to . But while homeowners have a , they often run into roadblocks.

As a and a , we have been working with communities as culturally and politically different as as they recover from disasters to understand what stands in the way of a sustainable, resilient recovery.

Up-front costs have played a big role in how these communities recover, but so have homeowners’ and builders’ perceptions – and misperceptions – about costs and regulations.

Rebuilding Costs

After a disaster, people need to get into housing quickly. At the same time, the costs to rebuild sustainably and resiliently can be high. Builders and building supplies often , which can .

This is set against a backdrop of the Federal Emergency Management Agency’s , which is intended , and a widespread from disaster-prone markets. Other take months to arrive.

Even for people whose homes are insured, payments from what existed before. Thus, the amount of money available for rebuilding can be considerably less than the of rebuilding resiliently.

Less quantifiable, but no less real, is the cost of navigating the rebuilding process. For many people, this starts with figuring out how to apply for government aid, dealing with insurance companies’ requirements and then deciding how and when to build.

All require research, paperwork and meetings.

A critical player in the rebuilding process is . These departments manage construction standards, approval processes, permits, fees and other aspects of what gets built. Those are vital to safe and resilient housing, but the longer and more complicated the building process, , both financially and psychologically.

Navigating bureaucracy can be challenging for everyone, but it can be especially hard on people who , or , which we often saw after the devastating Maui fires in 2023.

Building Back Better Costs Less Than People Think

We also have found significant problems with perceived costs. Both residents and building professionals often overestimate up-front costs of adopting newer technologies that may have substantial benefits for sustainability and safety.

After the Marshall Fire in Boulder County, Colorado, in 2021, we conducted with builders and owners of some of the more than 1,000 homes and businesses destroyed by the blaze. We found that some builders discouraged residents from pursuing new technologies, such as installing energy-efficient air-source heat pumps. Builders quoted installation costs ranging from no additional premium over conventional technologies to tens of thousands of dollars, creating significant cost uncertainty for residents.

We also heard repeatedly from building professionals on Maui that the pace of change in the building industry, especially changes driven by regulation, can be challenging, costly and require time to retrain crews.

For example, to withstand high winds in Hawaii, many homes should be built with framing system. However, one resident who worked in the building sector showed us the straps at his rental property, drawing our attention to the fact that they were installed incorrectly. Builders also told us that the large number of nails required in some situations causes splits in the framing system, leading builders to question the regulatory standards.

In some cases, building professionals or residents may perceive that something is more expensive than it actually is. In Puerto Rico, our data showed that communities were surprised that hurricane straps, which can help keep wooden roofs from tearing off in high winds, can be quite cost effective. One local builder said he was surprised that “it is $35 to make sure your roof doesn’t blow away.”

Getting Better Information

What’s clear from our research is that both residents and builders need accurate, easily accessible information about how to efficiently reduce rising disaster risk.

People were seeking this information across all of our cases. However, people’s knowledge is often circumscribed by their past experiences.

For example, Puerto Ricans have been working hard to because they have seen these panels fly away in hurricanes. But they are not as commonly addressing the roof structure and its connections.

In Alaska, where large earthquakes are common, many people we spoke to believed inspections would make sure foundations were being built correctly. But in most Alaskan communities, this doesn’t happen. is an exception.

As a society, streamlining the rebuilding process so it delivers pragmatic information that emphasizes high-impact changes could make resilient choices easier. This technical information is available in the form of technical reports and government studies, but it still needs to get to both builders and residents in a clear and concise manner. This is rare today, though some organizations are making efforts, such as the – the College of Architects and Landscape Architects of Puerto Rico – which shares easy-to-understand advice for homeowners.

Simple changes can make a big difference. Data from the Marshall Fire in Colorado suggests that . Reducing their use could cheaply and effectively reduce the risk of homes burning in future fires.

Making the rebuilding process as efficient as possible can also be a big win without any change to existing requirements. That has been happening on Maui with the implementation of , which has reduced a 400-plus day process to 15 days. With third-party plan review, building regulations remain the same, but instead of a government worker reviewing a building permit for compliance, a contractor does so.

Finally, while there are unavoidable costs to rebuilding, there are also real benefits in how mitigation and resilience measures . Incentives, and disincentives, can help homeowners, building professionals, insurers and governments invest in more resilient buildings.
