Why an Asbestos Inspection May Not Be Required — But Is Still Recommended

Under Trigger ≠ Zero Risk Inspection Not Required… But Still Smart (and OSHA-Savvy)

When the Wizard shows “Inspection Not Required (Recommended),” it means your project falls below Colorado’s regulatory trigger levels. That’s good news — but it doesn’t mean asbestos risks can be ignored. Here’s why:

1. Colorado’s Trigger Levels
Colorado Regulation No. 8, Part B (Asbestos) sets material quantity thresholds that determine when an asbestos inspection and CDPHE notification are mandatory:

• Single-Family Residential Dwellings (SFRD):
  More than 32 square feet, 50 linear feet, or the volume of a 55-gallon drum of suspect material.
• Public & Commercial Buildings (P&C):
  More than 160 square feet, 260 linear feet, or the volume of a 55-gallon drum of suspect material.

If your renovation project is below those levels, CDPHE does not require an inspection or notification.

2. OSHA Still Applies to All Work With Asbestos-Containing Material (ACM)
Even when CDPHE doesn’t require an inspection, OSHA regulations (29 CFR 1926.1101) still apply if any asbestos-containing material is disturbed.

• Employer responsibility: Contractors must assume suspect materials contain asbestos unless proven otherwise.
• Worker protection: Employees must be trained and notified if they may disturb ACM, even in small quantities.
• Controls: Safe work practices, PPE, and waste handling rules still apply.

3. Why an Inspection Is Still Recommended

• Peace of mind: Many common building materials contain asbestos, and it’s often invisible without testing.
• Liability protection: If workers unknowingly disturb ACM, both the contractor and property owner could be held responsible under OSHA.
• Cost savings: Discovering asbestos mid-project can cause delays, higher disposal costs, and even fines.

A small inspection up front ensures everyone knows what they’re working with, even if it’s not legally required.

✅ In Plain English
If your project is under Colorado’s trigger levels, you don’t need to notify CDPHE or file an inspection report — but you and your contractor are still responsible for OSHA compliance if ACM is present.
That’s why we recommend an inspection even when not required: it protects workers, prevents surprises, and ensures your project stays safe and compliant.
