The Parisian Inter-landlord Surveillance Group (GPIS) in Paris and the Inter-neighborhood Tranquility and Safety Group (GITeS) in Toulouse are two groups that intervene on behalf of social landlords to enforce tranquility and security in their buildings. They work primarily during late afternoon and evening hours, weekdays and weekends.
Summary:

The GITeS teams have the mission to develop social connections with the tenants and local stakeholders, by going to meet them and creating a relationship of trust. To do this, the security agents ensure a visible presence in the buildings and common areas of the housing stock they monitor. They are tasked with conducting residence inspections with the objective of tranquility and prevention. The sovereign missions of police remain fully and exclusively exercised by the law enforcement forces, under the direction of the Prefect and the Public Prosecutor.

The GPIS intervenes for landlords in Paris 7/7 days from 5:30 PM to 4:30 AM, its mission is to prevent delinquency, ensure a human presence in the evening and at night, strengthen the sense of security of tenants and assert the authority of landlords on their sites. It is coordinated by an Operational Command Post (PCO) and enables the processing and analysis of gathered information, for daily adaptation of the field deployment.
The covered property is defined by the landlords and meets the dual necessity of maintaining territorial coherence and acting primarily on sites where indicators reveal findings of insecurity. The GPIS action specifically targets the most vulnerable populations, generally victims of delinquency and incivility in the Parisian social housing stock.

Professional surveillance agents can intervene directly on certain infractions committed against the buildings they monitor following the global security law of March 17, 2021. They have the possibility to issue fines for any infraction that harms the buildings or group of buildings for which they provide surveillance and security functions. They are authorized by the State representative in the department. The official reports they establish are transmitted to the Public Prosecutor through the territorially competent Judicial Police Officers within five days following the observation of the subject of the official report.
