Retaining walls over 4 ft tall (measured from bottom of footing) in Duval County require a building permit and engineered drawings. Walls under 4 ft supporting only soil (no surcharge) are generally permit-exempt. All walls in drainage/flood areas need review.
Jacksonville Building Inspection Division requires a permit for retaining walls exceeding 4 ft in height (measured from the bottom of the footing) per Florida Building Code §1807. A Florida-licensed engineer's sealed plan is required for walls over 4 ft or when supporting a surcharge (sloped backfill, driveway, pool). Walls in a FEMA special flood hazard area need additional review regardless of height. Gravity walls (segmental block under 4 ft, no surcharge) are typically permit-exempt. Proper drainage (weep holes, gravel backfill, drainage fabric) is required. Walls along the St. Johns River/Intracoastal that serve as bulkheads/seawalls have additional Army Corps and SJRWMD permitting.
Unpermitted retaining wall over threshold: stop-work, 2x permit fee, engineering review required. Collapse causing neighbor damage: civil liability plus code fines up to $250/day.
