Retaining walls are a common feature in housing developments, but under HUD’s NSPIRE inspection standards, not all retaining walls are treated the same. The key is knowing which walls are inspectable and what specific conditions can be cited.

Which Walls Are Inspectable?

Under NSPIRE, retaining walls are generally only inspected when they meet the minimum height threshold:

  • Only retaining walls 24 inches (2 feet) or taller are inspectable.
  • Walls shorter than 24 inches (such as 12-, 18-, or 22-inch walls) are not inspected.
  • Landscape walls and decorative features are typically excluded.

This helps focus inspections on walls more likely to create safety or stability concerns.

What Inspectors Look For

The good news is that HUD is no longer concerned with:

  • Cracks in the wall
  • Rotted or splintered blocks
  • Missing or loose top blocks

The only defects that matter are if the wall is leaning from fill side or is partially or completely collapsed.

  • Health & Safety: Moderate
  • HCV Correction Timeframe: 30 days

Other imperfections, like cracks or minor missing pieces, are not considered defects.

Practical Examples

  • Non-inspectable wall: A 22-inch tall wall with loose or missing blocks is not a concern.
  • Inspectable but non-defective wall: A 30-inch wall with cracks but no lean is not a defect.
  • Defective wall: A 26- to 30-inch wall that is visibly leaning is a moderate defect.

Key Takeaways

  1. Inspect only retaining walls 24 inches or taller.
  2. The inspection focus is on structural stability, not cosmetic wear.
  3. Cracks, missing blocks, rotted wood, or splintered sections are not inspected.
  4. Leaning away from fill side and Collapsed retaining walls are a recordable NSPIRE deficiency.
  5. Moderate defects result in a 30-day repair timeframe.

Conclusion

INSPIRE inspections for retaining walls are straightforward. Property managers can save time and reduce inspection stress by focusing only on walls that are both tall enough to be inspected and leaning.
