Window Replacement · Plaquemines County, Louisiana
Permit required
In Louisiana, a Window Replacement requires a building permit.
Most of Plaquemines Parish is in Louisiana's wind-borne debris region (within a mile of the coast at 130 mph or more, or anywhere at 140 mph or more; here around 140-150 mph), so replacing windows requires a permit and the new windows and doors must be impact-rated (ASTM E1886/E1996) or protected by approved shutters. Louisiana has no statewide product-approval database like Florida's, so compliance is shown through manufacturer ratings or an engineer's design, and a PE seal is required for wind-load design in coastal parishes. Plans are reviewed under the Plaquemines Parish, LA (WBDR) code (IRC 2021 LSUCC); apply through Plaquemines Parish Permits before work begins.

Retrofit windows (inserting into existing frames) often do not require a permit, but new construction windows or altering the wall structure almost always requires an inspection.
With a growing population of around 22,803 residents, Plaquemines County maintains a relatively streamlined permitting process compared to major urban hubs. Processing typically takes 1 to 3 weeks.
Code Compliance & Inspections
Because Louisiana sits in a hurricane-prone zone, the Louisiana Uniform Construction Code requires exterior work to use wind-rated materials and proper anchoring (such as tie-downs and impact-rated components) to pass inspection.
