Home fortifications, from roof tie-downs to window protections, have been recognized as key factors in reducing losses, claims and premiums in hurricane-prone states like Florida.
But relying on the incentive of premium discounts is not enough to prompt widespread adoption of mitigation measures, especially for low- and moderate-income ho
useholds, according to a new study that examined more than 20 years of data from Florida’s Citizens Property Insurance Corp.
“Our findings underscore that rising insurance premiums can increase adaptation, but only if paired with policies that target financial constraints for low-income and low-wealth households,” the study concluded.
The paper was authored by four professors at three universities, including Vikas Soni, assistant professor and director of the Merrill Lynch Wealth Manageme
nt Center at the University of South Florida. It was published by the Brookings Institution’s Hutchins Center on Fiscal and Monetary Policy.
The study acknowledged that the $300 million My Safe Florida Home program, which prioritizes lower-income homeowners, provides state-funded matching grants of up to $10,000 for retrofits, for qualified applicants. And
property insurers in Florida offer discounts of as much as 44% for some mitigation steps, such as window and door opening protection. Opening protections and stronger roof-to-wall connections, such as hurricane clips and straps, can
provide the largest discounts, amounting to a mean value of about $6,000 over 25 to 30 years, the report indicated.
But the policyholders who need to save the most on homeowners insurance premiums are least likely to pay for protective retrofits, the study found. Wealthier home
owners will respond to higher insurance costs by investing more in climate-resistant building features. The premium discounts—greater for higher-value homes—outweigh the cost of hardening work.

eady binding budget constraint, crowding out the upfront expenditures required for adaptation,” the authors wrote.
Changes in public and insurance industry policy could help, they said. The My Safe Florida Home program, similar to mitigation grant programs in other states, offers
one template, the study said. But others are needed, including targeted subsidies for upgrades, more low-interest financing for home retrofits, and means-tested premium assistance programs that preserve the incentive to adapt while relieving financial strain.
The study was posted the same day another report found that property insurance rates are expected to more than triple in some parts of the country over the next decade.
Louisiana and South Carolina will see the steepest average premium increases by the year 2035—as much as 203% for South Carolina and 247% for Louisiana properties, said the study published by the Coalition for an Insurable Future and Mandala Partners. The Coalition is led in part by Carolyn Kousky, an economist with the Environmental Defense Fund and a former University of Pennsylvania professor. The results of the study were based on data from the Federal Emergency Management Agency, the Federal Insurance Office and other sources and studies.
