When you need this permit

  • A permit is required for the construction of a new fence or replacement fence made of ANY type of material — El Mirage's amendment to IBC/IRC 105.2 deletes the base code's exemption for fences not over 7 feet high
  • A permit is required for retaining walls over 24 inches (2 feet) in height — El Mirage's amendment deletes the base code's exemption for retaining walls not over 4 feet high, imposing a stricter, lower 24-inch threshold
  • Retaining walls 24 to 48 inches in height require plans showing how the wall and footings will be constructed; walls 4 feet (48 inches) or more require an engineered design with sealed, signed structural calculations
  • Site Plan with dimensions indicating fence/wall location and length required; a Neighboring Property Owner Authorization Form (notarized/completed by the adjoining property owner) is required for fences
  • Fees for fences are based on the valuation of the linear feet of the project; fees for retaining walls are based on valuation; a non-refundable $150.00 application fee applies to both

Tips

  • El Mirage is STRICTER than the unamended IBC/IRC on both fences and retaining walls: the base code's standard exemptions (fences <=7 ft, retaining walls <=4 ft) were expressly deleted by City amendment — a permit is required for a fence of any height/material and for a retaining wall over 24 inches.
  • A notarized Neighboring Property Owner Authorization Form (completed by the adjoining property owner) is required for fence permits.
  • Retaining walls 4 feet or taller, or walls deemed structurally bearing, require an engineer-sealed design and typically a more involved inspection process.
