Fences over 7 feet tall and retaining walls over 4 feet require a building permit in Jefferson County (Louisville Metro). Permits are obtained from Codes & Regulations. Lower fences need no permit but must comply with LDC height, setback, and material standards.
Louisville Metro (Jefferson County) requires a building permit for fences exceeding 7 feet in height and retaining walls over 4 feet. Applications can be submitted online or in person at Codes & Regulations (502-574-2508). Fences 7 feet or under do not need a permit but must comply with LDC height limits (max 8 feet for rear yard privacy fences), setback rules, and vision clearance requirements. Properties in historic preservation districts or design overlay zones require additional design review before a permit is issued. Decorative walls, trellises, and arbors are subject to the same permit and height rules as fences.
Installing a fence over 7 feet without a permit: additional fees, possible stop-work or removal order. Non-compliant fence (wrong height/zone): code enforcement citation.
