SHREVEPORT, La. (April 4th, 2026) - A new analysis reveals a stark reality for Louisiana homeowners: nearly half of all residences in the state predate 1983. This aging housing stock, while contributing to the state's unique architectural character, is increasingly becoming a point of concern as Louisiana faces escalating climate change impacts. The findings, originally reported by KTBS and based on data from Attom Data Solutions, paint a picture of a state where a significant portion of its homes lack the modern resilience features needed to withstand the growing threats of flooding, extreme heat, and increasingly severe weather events.

Attom's data indicates that approximately 49.7% of Louisiana's homes were constructed before 1983. This isn't merely a matter of aesthetic preference or historical preservation; it's a serious infrastructure issue. Building codes have evolved significantly in the decades since 1983, incorporating advancements in materials science, engineering, and a greater understanding of climate-related risks. Homes built prior to this period often lack crucial features like adequate insulation, impact-resistant windows, reinforced roofing, and elevated foundations - all vital for protecting against the specific challenges Louisiana faces.

Louisiana's geographic location makes it uniquely susceptible to the effects of climate change. The state is already experiencing more frequent and intense hurricanes, sea level rise, and inland flooding. Older homes, without the benefit of modern building standards, are demonstrably more vulnerable to these events. This vulnerability translates directly into higher repair costs, increased insurance premiums, and a greater risk of displacement for residents.

The Attom analysis placed Louisiana as the 10th most vulnerable state regarding older housing stock. Mississippi topped the list with a concerning 64.4% of homes built before 1983, highlighting a regional pattern of older infrastructure in the Southeast. Delaware, conversely, boasts the fewest pre-1983 homes at just 13.5%, showcasing the wide disparity across the nation.

Beyond Flood Risk: A Multifaceted Problem

The risks associated with Louisiana's aging housing stock extend far beyond just flooding. Energy efficiency is a significant concern. Older homes tend to be poorly insulated, leading to higher energy bills for heating and cooling. As temperatures continue to rise due to climate change, this inefficiency will only worsen, placing a financial strain on homeowners and contributing to increased energy demand.

Furthermore, the lack of resilience in older homes is directly impacting the insurance market. Insurance companies are increasingly factoring climate risk into their pricing models, and homes built before 1983 are viewed as higher risk. This is leading to soaring insurance premiums in many parts of Louisiana, making homeownership increasingly unaffordable for some residents. In certain areas, insurance is becoming unavailable altogether, creating a crisis for homeowners.

What's Being Done, and What More Needs to Happen?

State and local governments are beginning to address the issue, but significant investment and a comprehensive strategy are needed. Programs offering financial assistance for home retrofits - such as adding insulation, elevating foundations, and installing impact-resistant windows - are crucial. However, these programs are often underfunded and inaccessible to many low-income homeowners who need them most.

"We're seeing a growing demand for resilience upgrades, but the cost is prohibitive for a lot of families," says Dr. Emily Carter, a coastal resilience specialist at Louisiana State University. "We need to explore innovative financing mechanisms, like low-interest loans and grant programs, to make these improvements accessible to everyone."

Another key area for improvement is building code enforcement. While modern building codes are designed to enhance resilience, ensuring compliance requires robust inspection processes and adequate staffing. Strengthening these systems is essential to prevent future vulnerabilities.

Looking ahead, Louisiana needs a long-term strategy that prioritizes both adaptation and mitigation. This includes investing in infrastructure improvements, promoting energy efficiency, and reducing greenhouse gas emissions. Addressing the vulnerability of the state's aging housing stock is not just an economic imperative; it's a matter of public safety and social equity. Ignoring this issue will only exacerbate the challenges Louisiana faces in a rapidly changing climate.
