This "first barometer on the application of rent control" is based on the analysis of 15.000 advertisements, listed between August 2020 and August 2021.
It appears that between these two dates "35% of housing exceeded the legally fixed rent ceilings". This rate is "stable over the period studied" and corresponds to other estimates by professionals in the sector.
The study specifies that an advertisement which exceeds the authorized ceilings "is not necessarily illegal", due to a possible difference with the lease actually signed, or the particular characteristics of the accommodation.
Ads above the ceilings "propose an average rent excluding charges of EUR 1.229 per month, which includes an average exceeding of the rent ceilings of EUR 196 per month", or an "annual drawdown of nearly EUR 2.400 per year for tenants who suffer them ".
"The most significant overruns are found in the richest arrondissements (1st, 7th, 9th, 16th), while the lower overruns are due to the 14th, 19th and 20th arrondissements," adds the document.
The rent regulations prohibit landlords from asking tenants for an amount greater than a given sum, which varies depending on the neighborhood depending on the state of the market. It applies in areas of more than 50.000 inhabitants "where there is a marked imbalance between housing supply and demand".
Provided for by the Elan law of 2018, the ceiling on rents only concerned Paris and Lille until June 1. It was extended on that date to nine cities of Seine-Saint-Denis in the Parisian suburbs, and at the beginning of September to the metropolises of Bordeaux, Montpellier and Lyon.
