Taller retaining walls need a building permit with engineer-sealed drawings. Mecklenburg's FAQ sets the trigger at 5 ft or more of fill; its permit guide says engineered plans for walls supporting more than 48 in of backfill.

What changes the answer

Note: Mecklenburg's two documents give different thresholds (5 ft vs 48 in).
