Do I need a permit for retaining wall construction in College Park?
Most likely yes. Retaining wall construction usually requires a permit in Georgia. Confirm the specifics with College Park.
The 4 foot retaining wall exemption quoted nationally comes from section R105.2 of the model code, which Georgia keeps only as a guide for local governments. Your city or county sets the height that triggers a permit. Even under the model exemption, a wall that supports a surcharge, such as a driveway, slope or structure above it, is not exempt. Section R404.4 of the residential code requires an engineered design for a wall that retains more than 48 inches of unbalanced fill, or a wall over 24 inches that resists loads in addition to soil. This wall will hold up a driveway, patio, structure or sloped ground, which puts extra load on it (a surcharge). Model code exemptions for short retaining walls specifically exclude walls supporting a surcharge. Surcharged walls commonly need an engineered design, drainage behind the wall, and an inspection, because a failure can undermine whatever sits above it.
