Dauphin Island falls under the International Building Code as adopted in Alabama, with a design wind speed of roughly 155 mph for this part of Mobile County. Along the Alabama Gulf Coast the code adds coastal wind-design provisions — stronger roof-to-wall and wall-to-foundation connections and impact-rated openings — and hurricane protection products should carry a large-missile impact rating (tested to ASTM E1886/E1996). A building permit is required for permanent installations, and work must be completed by a licensed contractor.
Around Dauphin Island, Mobile County Inspection Services (251-574-3507) permits and inspects work in unincorporated areas and enforces Alabama's coastal wind-design provisions and the county Flood Damage Prevention Ordinance; the Town of Dauphin Island and cities such as Mobile and Bayou La Batre permit their own construction.

Can't Put Your Shutters Up Yourself?
Putting up panels means hauling them out, climbing a ladder, and drilling — usually in a rush as a storm bears down. For seniors and anyone with mobility or balance limits, that's not safe to do alone. Local crews will mount or deploy your shutters for you ahead of the storm, so your home is protected without you ever getting on a ladder.

Why Shutters Matter in Dauphin Island
As a low, narrow barrier island, Dauphin Island has been overwashed and cut in two by multiple hurricanes, including Katrina and Sally. With open Gulf on one side and Mississippi Sound on the other, there's nowhere for surge to go but through — and that exposure makes the highest-rated impact shutters close to a necessity here.
No place in Alabama carries a longer hurricane scar than Dauphin Island. Hurricane Frederic destroyed the island's bridge to the mainland in 1979; Hurricane Katrina overwashed and cut the low west end in 2005; and Hurricane Sally battered it again in 2020. As a narrow barrier island with open Gulf on one side and Mississippi Sound on the other, the island takes surge and full Gulf wind head-on, with nowhere for water to drain. That extreme exposure is why island homes need the highest-rated impact protection on every opening.
