“Most people presume that here in the United States — across all of the United States — we probably have building safety standards. But they would be wrong,” says Cope.
Many states, including Delaware, Alabama, and Texas, develop building codes on a local level, which means millions of homeowners live in areas with outdated regulations, if any. Unsurprisingly, Delaware, Alabama, and Texas have the lowest ratings in the IBHS report.
IBHS created FORTIFIED, a voluntary beyond-code construction and re-roofing method, in response to the lack of standardized building codes. The I-Codes, developed by the International Code Council (ICC), offer similar protection to homeowners.
“We have the information; we have the knowledge,” says Cope. “If people would simply use the model building codes that we have, we would be in a good spot.”
Louisiana, one of the most improved states according to the report, now uniformly enforces the ICC’s latest International Residential Code (IRC). The state saw five landfalling hurricanes between 2020 and 2021, the latest being Hurricane Ida. The resulting damages and strain on the private insurance market may have spurred Louisiana to update building codes.
Building code adoption is often reactionary, says Cope. “My home state of Florida was walloped by Hurricane Andrew in 1992. … Florida doubled down and said, ‘We will not allow this type of thing to happen to us again.’ It took 10 years because the good, modern Florida Building Code came out in 2002 … but Hurricane Andrew was a game-changer, watershed moment.”
Mobile County and Baldwin County in Alabama had a different watershed moment — Hurricane Katrina, which displaced 1.5 million residents across Alabama, Louisiana, and Mississippi. “Those two counties have adopted most of the provisions of FORTIFIED [building standards], even though Alabama doesn’t have a statewide code,” says Cope.
States don’t always move toward stronger building codes. North Carolina, which enforces the out-of-date 2015 IRC, put a moratorium on new building codes until 2031. Code updates include information about recently developed building materials and their performance against natural catastrophes.
Hurricanes drive mortgage delinquencies
Homeowners already feel strained, and an active 2024 hurricane season could displace those living on the financial edge. Costly wind damage is unaffordable to fix for some homeowners, especially without insurance, and standard homeowners insurance policies don’t cover flood damage.
Nearly three-quarters (74%) of homeowners Insurify surveyed don’t have flood insurance, and among that group, 13% thought their regular home insurance policies covered flood damages.
Thirty percent of homeowners in a 2024 Insurify survey said they can’t afford their current mortgage interest rate now or in the future. Among that group, about 21% said they can afford it now but not for long, nearly 9% are tapping into savings until they refinance, and less than 1% say they can’t afford their home any longer.
Hurricanes often drive residents out of their homes permanently. Mortgage delinquency rates in Louisiana’s Houma metro area increased from 1% to over 7% in the month following Hurricane Ida, according to CoreLogic.
Yet homes constructed under modern building codes reduced the jump in mortgage delinquencies following major hurricanes by nearly 50%, a joint study by CoreLogic and IBHS found.
Weathering the storm
The more active hurricane season forecasted for 2024 reflects a larger pattern. Extreme weather events will continue to increase due to climate change, the NOAA predicts. Still, homeowners can take proactive steps to mitigate damage to their homes and lower their insurance premiums.
Gee recommends homeowners make resilient choices when it’s time to renovate or remodel. “Installing storm shutters, reinforcing roof attachments, and upgrading to impact-resistant windows and doors are a few ways to mitigate damage, and many insurance carriers provide discounts, as this reduces the chance of loss on the insured’s property.”
Cope echoed this sentiment, recommending homeowners look up their local building codes on Inspect to Protect and refer to the IBHS FORTIFIED standards if an up-to-date code isn’t in place. Local grants, like the Louisiana Fortifiy Homes program, could cover some of the cost by providing financial assistance for FORTIFIED Roof upgrades.
Improvements unrelated to storms can further lower insurance premiums, says Gee. “Examples include discounts for installing security systems, smoke detectors, fire alarms, and other safety features that can reduce the risk of property damage and insurance claims.” Bundling home and auto insurance or raising deductibles can reduce premiums even more.
Cope believes modern building codes can mitigate damage and reduce pressure on the insurance market as the U.S. experiences more frequent and severe weather events.
“Combining the sheer number of [weather] events with inflation on materials and supply chain difficulties, we’re seeing ripples in the insurance market that we haven’t seen before occurring in multiple states,” says Cope. “When these pressures hit us, the only thing that can alleviate that is more resilient construction.”
Methodology
Insurify data scientists determined average home insurance rates by combining real-time quotes from partner carriers and aggregated rate filings from Quadrant Information Services.
Rates represent the average annual cost of an HO-3 insurance policy for homeowners with good credit and no claims within the past five years. The policy covers a single-family frame house. Coverage limits are $300,000 dwelling, $300,000 liability, $25,000 personal property, $30,000 loss of use, and a $1,000 deductible.
Statewide costs reflect the average rate for homeowners across ZIP codes in the 10 largest cities. Insurify data scientists analyzed insurance company rate increases implemented throughout the second half of 2023 and into early 2024 to project end-of-2024 rates.
