In the 80's. Mine in the early 80's and my dad's in the mid 80's. He is in a 3 story, multi-building retirement condo complex and it has seen upgrades with a new roof and reinforced hurricane glass installed in all the windows a few years back. Mine still has a lot of the original windows that would likely be the first to go in any serious wind. His place also built a hurricane rated shelter/auditorium from the ground up in around 2008. It's big enough to fit the entire community. We are both pretty inland, dad like 4 miles from the ocean and me closer to 9, so flooding has historically never been a major concern. For any real storm I'd be over there to help him out since the roads would likely be blocked for days after a storm.When was your building built?
