This case involves a commercial property that suffered a significant decrease in property value due to the negligence of the building’s property manager. The property manager had been told about an electrical issue that was causing short circuit malfunctions building-wide. The property manager’s primary tenant was the owner of a small restaurant. In spite of the tenant reporting the issue on many occasions, the property manager made no attempt to rectify the issue. Eventually, there was a building-wide power outage which lasted over a week. The tenant was unable to operate her business during this time. The tenant also lost a significant amount of food that was refrigerated in the building. It was alleged that because these issues were not fixed, the tenant was overpaying in rent for months before the incident. A commercial leasing and rental value expert was sought to discuss how these issues could affect the rental value of a property. The expert was also asked to determine what the proper rent should have been for a property with these types of problems.
