What should I check before buying new construction in Sullivan's Island?

Check the builder's warranty terms, the septic or public sewer setup, and current flood zone maps before buying new construction on Sullivan's Island, since barrier island lots carry different insurance and elevation requirements than a mainland subdivision. Confirm the lot's exact flood elevation certificate before assuming a quoted insurance rate holds.
