Do you need a permit for Window Replacement in Galveston County?
In Texas, a Window Replacement requires a building permit.
Galveston is one of the 14 Texas coastal catastrophe-area counties, so replacing windows must meet the Texas Department of Insurance (TDI) windstorm standard: the work has to be inspected and certified with a WPI-8 (applied for before work begins), and the windows must be TDI-evaluated and impact-rated, or protected by approved shutters, against wind-borne debris. The WPI-8 keeps the home eligible for windstorm and hail (TWIA) insurance. A city building permit may also apply and is handled locally. Plans are reviewed under the Galveston County, TX (TDI windstorm / WPI-8) code (IRC 2018 IRC (TDI)); apply through Galveston County Engineer before work begins.
