Commercial Door Failed ADA Inspection? How To Fix Your Threshold


Commercial Door Failed ADA Inspection? How To Fix Your Threshold

If your commercial door failed ADA inspection, the issue is often the door threshold height,an abrupt transition, or a trip hazard at the entry. The good news: most ADA threshold violations are fixableby selecting the correct ADA compliant commercial door threshold (and pairing it with the right sealing method).

This page walks you through the most common ADA threshold failure reasons, what to measure, and the bestproduct-category solutions to get your opening back into compliance.


Why Commercial Doors Fail ADA Inspection at the Threshold

  • Threshold is too tall (common after door replacement or retrofit)
  • Edge is too abrupt (not beveled / harsh transition)
  • Threshold creates a trip hazard at the walking surface
  • Incorrect exterior sealing approach (using a non-ADA profile to stop water/drafts)
  • Damaged or worn threshold that no longer transitions smoothly

Step 1 - Measure What the Inspector Measured

To fix the issue quickly, you need two measurements:

  • Threshold height (highest point from finished floor)
  • Transition style (vertical edge vs. beveled / ramped)
Fast rule: If your threshold is above 1/2", it is often the reason you failed ADA. If it is between 1/4" and 1/2", it typically needs a beveled transition to be compliant.

Step 2 - Choose the Correct ADA Fix (Based on the Failure)

Fix A: Threshold Too Tall (Most Common ADA Failure)

Best solution: Replace with a compliant 1/2" ADA accessible threshold designed for commercial openings. This resolves most “threshold height” inspection failures.

Fix B: Trip Hazard or Slippery Entry (Liability + ADA Concern)

If the threshold surface is slick or the transition is unsafe, use a threshold withslip-resistant traction while maintaining ADA-friendly height.

Fix C: Exterior Door Needs Sealing (But Must Stay ADA Compliant)

Exterior doors still need protection from water, drafts, and air infiltration. The fix is choosing an ADA-friendly threshold approach and pairing it with the right sealing components.

Common “Quick Fix” Mistakes That Keep Failing Inspection

  • Adding a tall threshold to stop water/drafts and accidentally creating an ADA violation
  • Installing a threshold without addressing an uneven floor - creates a new trip edge
  • Using a worn threshold with dents/peaks that exceed the intended transition height
  • Trying to solve everything with a door sweep only (doesn’t fix the floor transition)

What If This Is Also a Fire Door Opening?

Some openings must meet both ADA accessibility and fire door requirements.If the opening is rated, use compliant, code-driven threshold options.
