Do I need a permit for retaining wall construction in Mountain Home?
Most likely yes. Retaining wall construction usually requires a permit in Arkansas. Confirm the specifics with Mountain Home.
The model IRC exempts retaining walls not over 4 feet measured from the bottom of the footing, unless supporting a surcharge or impounding certain liquids (R105.2). The State Fire Marshal's rule changes list no Arkansas amendment to R105. Taller walls and walls near structures or property lines are the usual permit and engineering triggers. Arkansas has no statewide residential permit office: building permits come from a city or town (or a county that chose to run a program), so the first question is which local office, if any, covers the address.
