When considering the purchase of any building, the due diligence process should include a thorough review of the existing elevator equipment. The function of due diligence is to independently verify all representations made by a prospective seller as well as to uncover pertinent facts which have not been disclosed but which are important to the buyer. Third party assessments of existing vertical transportation systems will assure the soundness of one’s investment, or in some instances, shed light on situations that require immediate attention and hundreds of thousands of dollars to correct. In our evaluation of the elevators, we consider safety, obsolescent equipment, code compliance, barrier free compliance, equipment condition, level of maintenance being provided and ability of the system to serve the building.
