The Paris City Council approved the Housing Affordability Act on 2 July. The legislation channels direct payments to qualifying tenants in Le Marais and imposes new annual rent caps on pre-1948 properties in the same streets.

Housing costs in central Paris have climbed steadily since 2022. The bill responds to data in the City of Paris housing observatory report that showed average rents in the 4th arrondissement reaching 32 euros per square metre in 2025. Local services such as the mairie du 4e have recorded a 14 percent rise in eviction filings over the same period.

Daily costs for residents

Tenants who meet income thresholds can now apply for monthly assistance of up to 280 euros through the local housing office. A household on rue de Turenne would use the payment toward the existing lease rather than facing relocation outside the historic core. Property owners of older buildings must limit increases to 2.8 percent per year, a figure drawn from the national inflation index published by INSEE. Commercial leases on rue des Rosiers fall outside the cap, leaving shop operators to negotiate directly with landlords.

Residents who already receive national housing benefits will see the new local payment added on top, according to the text of the act. Those above the income ceiling receive no additional support and will absorb the full capped increase. The legislation states that funds come from the 2026 municipal budget line for urban housing, which totals 312 million euros across all arrondissements.

Next steps for implementation

Applications open on 1 September at the mairie du 3e and mairie du 4e. Staff will process claims in order of submission and issue the first payments in October. Property owners must file updated lease registers with the prefecture by 15 October or face administrative fines set at 1,500 euros per property. The City of Paris housing department will publish quarterly compliance reports beginning in January 2027.
