Summary

In the zoned areas of unincorporated Oconee County, retaining walls are exempt from the yard setback rules that apply to buildings. Section 38-9.3(2)j lets fences, freestanding walls, retaining walls, hedges and septic lines sit in any required front, side or rear setback, so long as the structure stays entirely on the owner's own property.

These county ordinances apply to unincorporated areas of Oconee County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Steps and heating and cooling units may project into a required yard a distance not to exceed five feet but no closer than five feet of a property line. Fences, freestanding walls, retaining walls and appurtenances, hedges, and septic lines may be located in any setback, so long as they remain on the property.

Full Breakdown

3 exempts the unzoned Control Free District from every dimensional rule except this setback section, so the exemption reaches even unmapped land. Yards are measured inward from the front, side and rear property lines, or from the road right-of-way where one projects over the line, and whatever is left after those yards is the lot's buildable area. Subsection (2)i lets ordinary architectural projections such as window sills, cornices and eaves intrude up to two feet into a required yard, and subsection (2)j allows steps and HVAC units to project up to five feet into a yard provided they stay at least five feet from the property line.

The same subsection then draws a sharp line for site features: fences, freestanding walls, retaining walls and their appurtenances, hedges and septic lines carry no setback distance at all and may be located anywhere within a required yard, including hard against a property line, as long as the structure remains on the owner's own parcel. The section sets no maximum height or footing requirement for a retaining wall and does not require a zoning permit to build one; a taller or structurally engineered wall still falls under the permitting and inspection process the county administers under chapter 6, Buildings, of the Code of Ordinances.

Because the exemption reaches every setback rather than just the rear or side yard, a homeowner terracing a sloped lot along Lake Keowee or elsewhere in the county can run a retaining wall along a front property line without seeking a variance from the Board of Zoning Appeals.

Violations & Fines

Chapter 38 has no dedicated retaining-wall penalty. A wall built in violation of another zoning standard, such as encroaching onto a neighboring lot or a road right-of-way, is enforced under the county's general penalty in Section 1-7: a fine and/or imprisonment up to the jurisdictional limit of an Oconee County magistrate's court, with restitution possible for actual damages, and each day the violation continues counted as a separate offense.

Frequently Asked Questions

Do I need a setback for a retaining wall in unincorporated Oconee County?
No. Section 38-9.3(2)j of the Zoning Ordinance exempts fences, freestanding walls, retaining walls, hedges and septic lines from the front, side and rear setback rules that apply to buildings, so a retaining wall may sit anywhere in a required yard as long as it stays on your own property.
Can I build a retaining wall right on my property line?
The zoning code allows it. Unlike steps or HVAC units, which must stay at least five feet off the line, retaining walls carry no minimum distance under Section 38-9.3(2)j, so long as the wall itself does not cross onto a neighbor's parcel or the road right-of-way.
Does the county require a permit to build a retaining wall?
The zoning ordinance itself does not condition a retaining wall on a zoning permit. Structural or taller walls, however, still have to satisfy the building permit and inspection requirements the county applies under chapter 6 of the Code of Ordinances before construction begins.
Does this rule apply near Lake Keowee?
Yes, the setback exemption in Section 38-9.3(2)j applies countywide in the zoned areas, including lakeside parcels, but shoreline construction near Lake Keowee or Lake Jocassee must still meet the separate Lake Overlay District standards in Section 38-11.1, including its vegetative buffer and silt fence rules.
