Retaining Wall Permits

Retaining walls are structures designed to hold back soil between areas of different elevations.

A Retaining Wall Permit is required when installing a new retaining wall or replacing an existing retaining wall on residential or commercial properties.

When a Retaining Wall Permit Is Not Required

A separate Retaining Wall Permit is generally not required when the wall:

• Measures 4 feet or less from the bottom of the footing to the top of the wall at the same section
• Does not support a surcharge

All retaining walls require an indemnification letter.

Additional zoning regulations related to rear-yard grading may restrict retaining walls on certain properties. Refer to Section 9.4.3 of the Development Code for additional guidance.

Who Can Apply for a Retaining Wall Permit?

Retaining Wall Permits may be obtained by:

• Licensed contractors
• Property owners, if the property is their current permanent residence

A professionally engineered signed and sealed design is required for retaining walls 6 feet or taller.
