Alpharetta, GA Fence Regulations: Height Limits (2026)

The Unified Development Code splits fence height regulation across two subsections in the City of Alpharetta. Section 2.3.6.A sets the baseline: 6 feet maximum on residential property and 8 feet maximum on non-residential property, for any fence or wall used as a fence. The Ordinance allows that cap to be exceeded by up to 50% on sloped lots, which lets a homeowner keep the top of the fence level even where the ground drops away, rather than stepping the panels down the slope. Section 2.3.6.B then layers a separate, lower limit at corners and driveways to protect sight lines: no wall, fence, shrub or hedge taller than 3 feet can sit within 20 feet of where two streets intersect, or within 10 feet of the edge of a driveway that leads to a street.

That 3-foot cap applies even to landscaping, not just built fencing, so a tall hedge at a corner lot is treated the same as an oversized fence panel. The same subsection requires fences and walls to sit at least 5 feet back from any required landscape strip or buffer, to leave room for planting and maintenance, unless approved otherwise at a public hearing. Community Development measures compliance from finished grade, and the sloped-lot allowance and the corner-visibility limit are enforced together, so a fence can be tall along most of a sloped lot's length but still has to drop to 3 feet as it nears a street corner.
