Windows Code Requirements in Mississippi

State with significant severe hail frequency per NOAA SPC storm reports. Insurance restoration contractors should document pre-existing hail damage and recommend impact-resistant materials.

Special Flood Hazard Areas with established BFE throughout Mississippi. Major flood zones: Mississippi River (entire western border), Pearl River (Jackson area), Yazoo River (Delta), Pascagoula River (southeast), and numerous tributaries. Delta region particularly flood-prone. Coastal A-zones (CAZ) with wave action also present.

All of Mississippi is designated hurricane-prone region per ASCE 7. Wind speeds range from 115 mph (northern MS) to 180 mph (immediate Gulf Coast). Hurricane Katrina (2005) caused catastrophic damage with 150+ mph winds and 20-30 ft storm surge. Hurricane Camille (1969) also devastated coast.

DOD TIP Zone 1 (Very Heavy) — highest probability of subterranean termite infestation. IRC Section R318.1 requires termite protection measures for all wood structures.

Coastal high hazard areas with velocity wave action and established Base Flood Elevations. Extensive along entire Mississippi Gulf Coast. Hurricane Katrina storm surge reached 20-30 feet in some areas. V-zones subject to wave action and debris impact.

State within or adjacent to the tornado corridor. NOAA SPC data confirms significant tornado frequency. Enhanced structural requirements apply per IRC R301.2.1.2.
