Do I need a permit for retaining wall construction in Lexington?

Permit may be required

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

Under the 2018 IRC R105.2, a retaining wall is exempt only if it is not over 4 feet high, measured from the bottom of the footing to the top of the wall, and is not supporting a surcharge. The 2018 IRC list of work exempt from permit (section R105.2) comes with the 2018 IRC that Nebraska adopted by reference without amending its administrative chapter, but a city or county that adopts its own code may change it (71-6403, 71-6406). The first question is whether the city, village, or county where the property sits has adopted a building code and runs a permit office; Nebraska law lets each local government decide (71-6406).

Local detail for Lexington: City issues its own building permits under the state building code (state agency does not issue residential building permits in Nebraska).
