The International Building Code and International Property Maintenance Code, as adopted and amended by New Castle County, require elevators and conveying systems to comply with ASME A17.1 – Safety Code for Elevators and Escalators and ASME A18.1 – Safety Standards for Platform Lifts and Stairway Chairlifts. The codes require a maintenance program of periodic safety inspections to be performed by a Qualified Elevator Inspector (QEI) and annual testing performed by a Delaware Licensed Elevator Mechanic. In accordance with Delaware Code, only Delaware Licensed Elevator Mechanics are authorized to perform any maintenance, repairs, alterations, or replacements on any elevator or conveying system.
