Marseille has 40,000 substandard housing units, or 10% of the city's housing stock. A bill on the subject arrives in the Senate this week.

Since 2019, more than 23 cases have been processed. More than 150 reports to the courts have been made in three and a half years. A former police officer was sentenced to five years in prison for renting out his slums to vulnerable people. The city is now a civil party in the cases concerning slumlords.
