Do I need a permit for retaining wall construction in Kansas City?
It depends. Whether retaining wall construction needs a permit in Kansas City comes down to the details of your project.
The state has not adopted the model IRC list of work exempt from permit (such as the 200 square foot shed figure); the exemptions, if any, are whatever the city or county adopted. Height thresholds for a permit or an engineer come from the locally adopted code, not from the state. Contractors must give two full working days of notice before digging (K.S.A. 66-1804); an occupant digging at their own primary residence is excluded from the act (K.S.A. 66-1802(e)). A city or county that has adopted floodplain regulations under K.S.A. 12-766 can require a separate floodplain approval for work in a mapped floodplain.
