Colorado’s Regulation 8 requires asbestos inspection and compliance whenever renovation or demolition disturbs a certain amount of material, regardless of the home’s age—since even new buildings can contain asbestos.

Key Takeaways:

Age Doesn’t Exempt You

Reg 8 triggers inspection requirements based on the amount of material disturbed.

Under Colorado Reg 8, any renovation or demolition that disturbs asbestos-containing materials (ACM) must be inspected if the following thresholds are exceeded in a single-family dwelling:

50 linear feet of pipe insulation
32 square feet of other surface materials (e.g. drywall, ceiling texture)
Or the volume equivalent to a 55‑gallon drum of material

Know the Thresholds

Under Colorado Reg 8, any renovation or demolition that disturbs asbestos-containing materials (ACM) must be inspected if the following thresholds are exceeded in a single-family dwelling:

50 linear feet of pipe insulation
32 square feet of other surface materials (e.g. drywall, ceiling texture)
Or the volume equivalent to a 55‑gallon drum of material

Permitting and Timing

If asbestos is found—or assumed—the contractor must notify CDPHE and wait 10 working days before removing it. Skipping this step can result in permit delays and fines.

Best Practice

When advising clients on renovations or inspections, remind them to ask about Reg 8 testing early with their contractor, and verify it’s completed if their scope triggers the thresholds.

If you plan any remodel or demolition—even in newer homes—make sure asbestos compliance under Reg 8 is on your radar. Our intention is to educate, not alarm. We want to ensure that our clients are properly informed so that future costly surprises are avoided.
