At the beginning of last year (2021), Richter Condos installed a mechanized elevator for its tenants. The owner of the company, Charles Richter, recently returned from an industry equipment exhibition where he watched a computerized elevator demonstrated. He was impressed with the elevator's speed, comfort of ride, and cost efficiency.
