Since the 2019 reform, the building manager’s mandate is limited to a maximum of 3 years (renewable). The contract must be written and detail the duties, remuneration and termination conditions.

Relations with the landlord

Communications

The building manager communicates exclusively with the landlord, never directly with the tenant. The landlord is the mandatory intermediary.

In practice

Choosing a good building manager

  • Check IPI accreditation (Professional Institute for Estate Agents)
  • Compare fees and included services
  • Ask for references from other co-ownerships
  • Read the contract carefully (duties, extras, termination)

Supervising the building manager

  • Actively attend general assemblies
  • Request accounts and supporting documents
  • Appoint an auditor (mandatory)
  • Report shortcomings in writing

For the landlord

Include the building manager’s contact details in your lease and inform the building manager of each tenant change. Use a rental management software to centralise your exchanges with the building manager and charges tracking.
