A preventive maintenance program in an office building typically includes which of the following?

A preventive maintenance program is designed to keep building systems functioning efficiently and to avoid unexpected failures that can lead to costly repairs and disruptions. In this context, regular maintenance of elevators is crucial, as these systems are essential for daily operations in an office building. Routine inspection, operation, and cleaning of elevators ensure safety, reliability, and compliance with safety regulations.

Regular maintenance visits can help identify potential issues before they lead to significant malfunctions, making it an integral part of preventive maintenance. This not only enhances the users' experience by reducing downtime but also prolongs the service life of the elevators.

The other options focus on aspects that are generally not part of a preventive maintenance program. Upgrading tenant finishes and renovations of office spaces are capital improvements rather than routine maintenance tasks. Tenant relocation procedures are administrative actions that deal with occupancy rather than maintenance of the building systems. Hence, these choices do not align with the objectives of a preventive maintenance program.
