♦ All plans must be a minimum size of 18 x 24 inches.

♦ Along with the applications submit 2 sets of construction plans – If wall is greater than 4’ in height (measured from the bottom of the footing) or if it is supporting a surcharge or impounding Class I, II, or IIIA liquid, whether site-built or modular, must be designed by a Registered South Carolina Professional Engineer.

♦ Submit a Site Plan ‐ Show location of all retaining walls on site.

♦ The plan must reflect any special restrictions of work around the wall such as heavy equipment, trenching, etc.

♦ The City of Greer reserves the right to require pedestrian and/or vehicular guardrails. Details from the engineer will be required.

♦ Before the building permit can be issued the owner of the project must retain the services of a special inspection agency to conduct third party inspections of the wall construction.  This agency will need to submit a “Statement of Special Inspections” (City of Greer Special Inspections 2015 IBC) to the Building Official for approval.  This statement should include the name, license number and qualifications of those performing these services. Daily inspection reports will need to be kept on the job site at all times.  The Building Official will need to be notified of any discrepancies. The third party agency is required to submit a “Final Statement of Inspections" to the Building Official at the completion of the job.  

♦ After approval of the retaining wall plans, a Building Permit must be obtained by a properly licensed contractor.

♦ During construction of MSE Walls, a “third party” South Carolina licensed “Special Inspector” shall inspect the work at prescribed stages and certify that the construction complies with the approved plans and building code. A final report of special inspections is required to be submitted to the Building Official prior to a Certificate of Completion being issued.

♦ License Requirement – A City of Greer Business License is required (Business License Information Sheet), Contractor must be properly licensed with LLR.  For MSE Walls, a General Contractor with a Building Classification (BD) is required. For Poured in Place Walls, a General Contractor with a Concrete Classification (CT) is required.

♦ During construction of a poured in place wall, the City of Greer must inspect the setback requirements, foundations and all wall pours.  This is in addition to third party inspections. A final report of special inspections is required to be submitted to the Building Official prior to a Certificate of Completion being issued. 

♦ All walls must be permitted prior to the Grading permit being issued.  All walls must receive final inspection approval before other construction permits will be issued.
