Updated Florida building codes helped newer homes withstand Hurricane Ian

Newer homes seemed to fare much better than older structures during Hurricane Ian, suggesting that updated Florida building codes made a difference.

In the hardest-hit parts of southwest Florida, many newer structures remained mostly intact in the up to 120 mph winds generated by the hurricane. One photograph on one beach area shows 18 homes built before 1981 that were completely destroyed, but one house, built in 2020, appears to be almost unscathed.

That home is elevated above much of the storm surge level, but the roof also appears undamaged. CoreLogic says that wind losses in Lee County, one of the coastal areas with the most damage, were twice as high for structures built before 1996, when the state began tightening building codes for wind load.

CoreLogic’s computer models peg insured losses from Hurricane Ian from $22 billion to $32 billion, excluding flood damage. It’s much lower than losses coastal Florida would have seen if newer structures had not been built to the stronger standards, according to CoreLogic and other experts.

Yudelson, a Contributing Editor to Building Design+Construction, says, “It looks like a good year ahead for the green building industry. Based on our experience, it seems clear that green building will continue its rapid expansion globally in 2013 in spite of the ongoing economic slowdown in most countries of Europe and North America. More people are building green each year, with 50,000 LEED projects underway by the latest counts; there is nothing on the horizon that will stop this Mega-trend or its constituent elements.”
