Palm Coast, FL Fence Regulations: Retaining Walls (2026)

Section 4.01.02.A.3.d of the Palm Coast LDC requires walls to be made of (or equivalent to): (1) brick, Norwegian brick, jumbo brick, or stone; (2) split-faced block or finished masonry walls where block seams are not visible, with tile, brick, or decorative trim at or near the top; (3) wrought iron or aluminum fence in combination with brick, jumbo brick, stone, or finished masonry columns; (4) pre-cast concrete with a simulated wood, stone, or brick pattern; or (5) other materials approved by the Land Use Administrator. Section 4.01.02.A.3.e requires column spacing: 20-foot maximum for walls 100 linear feet or less; 30-foot maximum for walls 101-200 linear feet; 40-foot maximum for walls over 200 linear feet. Decorative columns may extend 12 inches above the wall (LDC 4.01.02.A.2.a). Engineered retaining walls supporting earth pressure are also regulated under the 8th Edition (2023) Florida Building Code (Building Chapter 18, Residential Chapter 4) and require a separate building permit when the height from the bottom of the footing to the top of the wall exceeds 4 feet, or for any height that supports a surcharge (slope, driveway, structure). Wall plans for taller or surcharged walls must be signed and sealed by a Florida-registered design professional. Palm Coast lies in flood zones (Flagler County) and any retaining wall in a Special Flood Hazard Area must also meet FBC flood-resistant construction standards.
