Full Breakdown
Palm Bay's fence-and-wall ordinance governs walls erected outside the building lines, including retaining walls: no more than 4 feet in a front setback and no more than 6 feet at any other location, with a 6-foot allowance on corner-lot side yards. Plans showing the wall's location and construction type must go to the Building Official for a permit before work starts. Retaining walls proposed inside a regulated floodway face additional engineering limitations under § 179.015(C), and no wall may be placed on a drainage or street right-of-way under § 176.004.
Violations & Fines
Building without a permit or exceeding the height cap is a code violation; the Building Official can order the wall removed or brought into compliance, and unpermitted work can delay certificate-of-occupancy inspections.
