Whitfield County, GA Fence Regulations: Retaining Walls (2026)

Section 5A-4-3(e) of the Unified Zoning Ordinance (Appendix A), within its Urban PUD Design Standards in Article 5A, sets three different retaining wall height ceilings depending on where the wall sits on a U-PUD-zoned residential lot. A retaining wall in the front yard is capped at four feet. One placed adjacent to a sidewalk along a public street is held to a stricter two feet, reflecting the pedestrian focus of the same article's streetscape rules. Interior side and rear yard retaining walls get the most room, up to eight feet.

The ordinance builds in one specific escape valve: administrative variations from these wall height requirements are allowed if the applicant can demonstrate a topographic hardship, a lower bar than the general 10 percent Administrative Relief process the Unified Board of Zoning Appeals otherwise uses under Section 5A-5 for other numeric design standards in Article 5A. These U-PUD limits are separate from the county-wide building permit rule at Section 5-37, which exempts a retaining wall from needing a building permit at all only if it is four feet or less in height, measured from the bottom of the footing to the top of the wall, and does not support a surcharge; a taller retaining wall, or one carrying a surcharge load, needs a permit from Whitfield County Building Inspections regardless of which zoning district it sits in.
