Retaining walls in unincorporated Lee County are permitted through the same Residential Fence or Wall process. Walls need a building permit, and if the wall exceeds 6 feet (excluding chain-link fences) the county requires blueprints signed and sealed by a Florida-registered architect or engineer showing footer, re-bar, and block courses.
Lee County treats walls (including retaining and garden walls) under the Residential Fence or Wall permit administered by Building and Permitting Services, with a 'Retaining' and 'Wall' permit type in eConnect. Because height is measured from the abutting property's existing elevation (LDC 34-1744(b)(1)), a wall cannot be used to raise grade and then add a full-height fence on top: a fence 'built on top of a berm, retaining wall or similar improvement' loses the grade-deviation allowance. For any wall over 6 feet the applicant must submit signed and sealed blueprints detailing the footer, re-bar, and courses of block. A No-Rise Certificate from a Florida engineer is required for earth-disturbing wall work in a regulatory floodway.
Building a retaining wall without a permit or required sealed engineering is a code violation subject to Lee County Code Compliance action and stop-work orders. Unresolved cases go to the Hearing Examiner/Special Magistrate for civil penalties (F.S. 162).
