Retaining Wall

Owners of properties with a retaining wall that faces a public right-of-way and has any portion of the wall extending ten feet or higher must have their retaining wall inspected every five years by a Qualified Retaining Wall Inspector (QRWI) and a condition assessment report of the inspection must be submitted to the Department by the QRWI within 60 days of completing the inspection.

To be qualified as a QRWI, a licensed structural engineer must apply to the Department’s Retaining Wall Unit. See NYC Construction Codes §28-305.1 and RCNY §103-09 for more information. View the current list of active QRWIs.

Retaining Wall Ratings

All retaining walls must be given one of four ratings by the QRWI:

  • Safe
  • Safe with Minor Repairs or Maintenance
  • Safe with Repairs and/or Engineering Monitoring
  • Unsafe

Steps for Compliance

  • Identify if the retaining wall must be inspected. If you have an entire retaining wall or part of a retaining wall on your property and it is ten feet or higher at any point on your property and faces a public right-of-way, you must have the wall inspected by a QRWI, and an assessment report must be submitted by the QRWI to the Department. Owners that share a retaining wall with one or more neighbors may hire one QRWI to inspect the wall.
  • QRWI conducts inspection. The QRWI conducts the inspection of the retaining wall and determines the rating of the wall.
  • QRWI submits condition assessment report and filing fees. Within 60 days after completing the assessment the QRWI must submit a report to the Department that meets, at a minimum, the criteria listed in 1 RCNY §103-09. The filing fees are payable by each property owner the report is submitted for, meaning a wall with multiple owners may have one report submitted for all of the owners but the filing fees must be paid by each individual owner.
