Collier County's LDC has no separate retaining-wall ordinance. Walls fall under the same fence and wall height rules of LDC 5.03.02, and a structural retaining wall needs a building permit under the Florida Building Code.
The Land Development Code regulates walls together with fences under Section 5.03.02, so the same maximum heights and the on-line/no-encroachment rules apply to freestanding walls. Height is measured from the ground level at the wall location, and existing grade may not be raised to gain height (LDC 5.03.02 F.1). Collier County does not adopt a distinct retaining-wall setback ordinance; structural retaining walls are engineered and permitted through the county building division under the Florida Building Code, which governs design, drainage, and safety. Confirm requirements with Building Plan Review before construction, especially near property lines, easements, or flood-prone areas.
An unpermitted structural retaining wall can draw a stop-work order and after-the-fact permitting. Walls exceeding LDC height or encroaching over the line may be cited by Code Enforcement.
