Official definition

This industry comprises establishments primarily engaged in providing operating staff to perform a combination of support services within a client's facilities. Establishments in this industry typically provide a combination of services, such as janitorial, maintenance, trash disposal, guard and security, mail routing, reception, laundry, and related services to support operations within facilities. These establishments provide operating staff to carry out these support activities, but are not involved with or responsible for the core business or activities of the client. Establishments providing facilities (except computer and/or data processing) operation support services and establishments providing private jail services or operating correctional facilities (i.e., jails) on a contract or fee basis are included in this industry.

Which code does this activity belong in?

Facilities support services establishments provide on-site operating staff to deliver multiple coordinated support functions within client facilities, such as janitorial work, maintenance, security, and mail handling. The boundary with services to buildings and dwellings lies in the integration and coordination of multiple support activities by the same establishment. When an establishment specializes in a single service such as janitorial or pest control work, it is classified in services to buildings and dwellings rather than facilities support services. Facilities support services establishments maintain overall responsibility for coordinating diverse support operations, whereas building services establishments focus on discrete specialized services.
