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.

Current penalty is the amount after any settlement or adjustment. Open cases show no amounts because citations are not final.
