Summary
Beaufort County does not set a stand-alone retaining wall height cap, but if a fence sits on top of a retaining wall or berm, the Community Development Code caps the combined height at whatever the underlying fence height limit would be for that yard.
F. Fences on Retaining Walls or Berms. If a fence is constructed on top of a wall or berm, the combined height of the fence and wall or berm shall not exceed the maximum height that would apply to the fence or wall alone.

Full Breakdown
40, which sets fence and wall heights at four feet in front and corner side yards and six feet in side and rear yards in the county's Transect Zones and C3 Zone, and eight feet in front, corner side, and rear yards in the C4, C5, and S districts. So a homeowner who builds a three-foot retaining wall and wants a fence on top of it in a T-zone side yard is limited to three additional feet of fence to stay within the six-foot combined ceiling.
5 lets an owner or a public agency submit a security plan to the Director seeking a taller combined structure, or the use of barbed or concertina wire atop it, if the Director finds the land faces materially greater theft or damage risk and the taller structure will not hurt the surrounding area's appearance or value. 2.
Violations & Fines
Exceeding the combined fence-and-wall height without an approved security plan is a Development Code violation under Article 9. The Code Enforcement Department serves a written notice under Section 9.4.40 identifying the section violated and the correction deadline; unresolved violations can draw a Uniform Summons Ticket into Beaufort County court. Section 9.5.10 sets the penalty at up to $500 or 30 days imprisonment per violation, with each day the oversized structure remains counted separately.
