Do I need a permit for retaining wall construction in Unincorporated Perry County?

The requirements below come from Alabama rules. They are not a statement that Unincorporated Perry County issues or does not issue permits.

Permit may be required

It depends. Whether retaining wall construction needs a permit in Unincorporated Perry County comes down to the details of your project.

There is no statewide Alabama retaining wall rule; the model code exemption for walls up to 4 feet is not a state rule, so the locally adopted code decides the height at which a permit is needed. Alabama law requires notice to the One-Call Notification System at least two working days before excavation near underground utilities (Code of Ala. 37-15-4). Cities and counties may separately regulate grading, drainage, and work in flood zones. 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.
