Retaining Wall Permit

A retaining wall permit is required for any wall supporting more than three feet of soil height,  or any retaining wall loaded by surcharge loading from any of the following elements:

  • vehicle traffic
  • passive soil pressure loading from adjacent structures
  • a sloping site
  • passive soil pressures from an uphill retaining wall influencing the load on the downhill retaining wall (typically from a terraced wall design)
