When Permits are Required
Permits are required for retaining walls that are over four feet as measured from the footing to the top of wall or for any wall that is supporting a surcharge. Applicants will provide a site plan and be required to submit engineered stamped drawings. These permits will be reviewed by Building, Engineering, and Planning divisions to verify compliance with various City requirements including structural integrity, impact on drainage, location in relation to easements and property lines.
Retaining walls that are four feet or less do not require a building permit, however, if they are part of a new construction project, they will need to be reviewed by Engineering for property line location and easements as part of the standard site plan review process.
All retaining walls must comply with Land Development Code §4-7-2-2. - Retaining walls.
What is Needed to Apply
Please include the following items with your online application. Incomplete applications will not be accepted.
- Plot plan with setbacks, easements and retaining wall clearly marked.

Submitting Your Application

Retaining walls over 4 feet will require a variance/minor modification. Once the Planning division has approved the wall, the permit can be issued. This will typically take 4 weeks to be completed.

Permits for retaining walls will be assessed a $50 permit fee, a $36 plan review fee, and Use Tax.
