Summary
Retaining walls in Suffolk are governed by the Virginia Uniform Statewide Building Code, and a permit is required once a wall exceeds four feet or supports a surcharge. When a fence sits on a retaining wall, Suffolk measures height under UDO Sec. 31-701(d).
The height of fences shall be determined by measurement from the ground level at all points upon which the fence is located. An increase in height shall be allowed when spacing for drainage under the fence is needed.
(2) The height and location requirements of this Section may be modified as part of a subdivision, planned development, or conditional use approval. For fences on retaining walls, see definition of a retaining wall.
(e) CONFLICT WITH OTHER REGULATIONS. If there is a conflict between the accessory dwelling unit standards of this Section and any other requirement of this Ordinance, the standards of this Section shall control. Otherwise, accessory dwelling units are subject to all other applicable requirements of this Ordinance.

Full Breakdown
Suffolk regulates retaining walls through the Virginia Uniform Statewide Building Code, which the city enforces. A building permit is required for a retaining wall over four feet measured from the bottom of the footing to the top, or for any wall supporting a surcharge such as a driveway, slope, or structure above it. Where a fence is placed on top of a retaining wall, Unified Development Ordinance Sec. 31-701(d) directs that fence height be measured from ground level and points to the retaining-wall definition for how the combined structure is treated. Engineered plans may be required for taller or load-bearing walls.
Violations & Fines
Building a retaining wall without a required permit, or exceeding an approved height, can bring a stop-work order, building-code penalties, and an order to correct or remove the wall.
