Pro Tip for New Hanover County
This is high-wind coastal country — the NC code sets 150 mph east of Hwy 17 (140 mph west), so order your metal building with an engineered, county-specific wind package. Flood-zone parcels will also need elevation and tie-down details, so flag those before you submit through COAST.
Site Notes for New Hanover County
Coastal high-wind zone (140-150 mph) plus salt-air exposure. Specify an engineered wind package and corrosion-resistant coatings, and expect flood-zone elevation and tie-down requirements near the water.
