Summary
Louisville Metro treats retaining walls like fences for height and setback purposes, capping most yards at 42-48 inches or 8 feet depending on location and district.
Fences and walls, up to 48 inches in height in the suburban form districts and 42 inches in the traditional form districts, may be located within required front and street side yards... Fences and walls up to 8 feet in height and constructed of a solid material (masonry, wood) with an opacity of at least 80% may be located within required side and rear yards... NOTE: Retaining walls shall be subject to the height and setback requirements of this section.

Full Breakdown
Louisville/Jefferson County's Land Development Code folds retaining walls into its fence and wall standards: a note under LDC 4.4.3.A.1 states retaining walls are subject to the same height and setback requirements as fences. That means front and street side yards cap out at 48 inches (suburban form districts) or 42 inches (traditional form districts), while side and rear yards allow up to 8 feet for solid masonry or wood construction with at least 80% opacity. Rules vary by zoning and form district, so check the district-specific standards before building. This applies within Louisville Metro's planning jurisdiction; independent home rule cities inside Jefferson County (Anchorage, Jeffersontown, St. Matthews, and others) may set their own standards.
Violations & Fines
A retaining wall built taller than the applicable fence height limit, or placed in violation of the required yard setback, is subject to enforcement by Louisville Metro Planning & Design Services (PDS), which can order the wall modified or removed as a zoning violation.
