Cape Coral, FL Fence Regulations: Retaining Walls (2026)

Section 5.2.7 of the Land Development Code regulates 'any fence or wall constructed on any property,' and its exceptions clause spells out what counts as a retaining wall: 'any structure, designed or built, to resist the lateral pressure of soil or other materials, including backfill, at a grade elevation change,' regardless of material, as long as its primary purpose is to stabilize soil that would otherwise move or erode. Small landscaping edging under 24 inches high that doesn't carry a surcharge load or affect slope stability doesn't count. The only retaining walls the section exempts outright are those directly tied to the support and installation of an elevated pool deck, including retaining walls used for fall protection around a raised pool.

Every other retaining wall on a lot falls under the general permit and height rules in Section 5.2.7.B and C: 'No wall or fence of any kind whatsoever shall be constructed on any lot until after the height, type, design, and location has been approved in writing and with a proper permit issued by the City.' In residential zoning districts the maximum height for a wall is six feet, rising to eight feet along a side that abuts a commercial or professional use. Property owners who need to exceed the standard height, setback, or material rules can request an administrative deviation, which the Director reviews for reasonable necessity and for whether it preserves the visual character of the property and surrounding area without harming public health, safety, or welfare.
