OSHA & wage-and-hour records
U.S. Department of Labor inspection and case records matched to this business by name and street address. Records from the last 5 years (since 2021-10-30) are shown. An inspection is not by itself a finding of wrongdoing, and these records do not affect the HomeProFax Score.
OSHA inspections (1)

|---|---|---|---|---|---|
| 2024-04-17 | 2024-08-06 | Colorado Springs | Inspected, no violations cited | — | OSHA inspection 1742219.015 |
Current penalty is the amount after any settlement or adjustment. Open cases show no amounts because citations are not final.
