Real estate rental is based on a precise legal framework that determines the rights and obligations of each party. Understanding the mechanisms of the lease, the rules governing rent control, and the legal protections helps avoid costly disputes, whether one is a tenant or a landlord.
Rent freeze on energy-inefficient homes: a game-changing constraint
Homes classified as F or G on the energy performance diagnosis (DPE) face a major restriction. In areas subject to rent control, it is prohibited to increase the rent of an F or G property, even between two tenants, beyond the simple adjustment according to the rent reference index (IRL). This prohibition remains in effect until energy renovation work has been carried out.

For a landlord, this means that acquiring a poorly rated property with the intention of renting it out without renovation effectively freezes rental income. The only way to regain flexibility on the rent is through renovations that allow the property to move out of the F or G category.
This rule, stemming from the Climate and Resilience Law, adds to the mechanism of rent freeze upon re-letting in tight rental areas. If the previous tenant has vacated the property for less than 18 months, the landlord cannot increase the rent, except for any unimplemented IRL adjustments or significant improvement works.

A landlord hoping to take advantage of a tenant change to increase the rent thus faces a double regulatory lock. Several resources detail the applicable rules regarding rental on Crédit et Immobilier depending on the type of lease and geographical area.

Lease contract and mutual obligations: what the law really imposes
The residential lease is not just a simple administrative document. It legally binds both parties to specific obligations, the breach of which can lead to the termination of the contract.
Landlord’s obligations
The landlord must provide a decent dwelling that meets legal criteria: minimum living space, absence of risk to safety or health, compliant electrical and gas installations. They must also provide the tenant with all mandatory technical diagnostics before signing.
- The DPE (energy performance diagnosis), which classifies the property from A to G and now conditions the very possibility of renting
- The lead exposure risk report (CREP), mandatory for properties built before 1949
- The state of natural, mining, and technological risks if the property is located in a concerned area
- The condition of the internal electricity and gas installations when these installations are over 15 years old
The landlord cannot demand any document in the application file. The list of supporting documents requested from the tenant is regulated by decree, and any requirement outside this list (bank statement, previous employer’s certificate) constitutes an illegal practice.
Tenant’s obligations
The tenant must pay their rent and charges as agreed, use the property peacefully, and be responsible for any damage that occurs during the rental period. They must also take out a home insurance policy covering rental risks and provide an annual certificate to the landlord if requested.
The entry and exit inventory is the central document in case of disputes over repairs. A poorly done or absent inventory almost always works against the landlord, as the law then presumes that the property was returned in good condition.
Protection of vulnerable tenants during a notice period
The right to housing does not stop at the signing of the lease. When a landlord wishes to reclaim their property, certain tenants benefit from enhanced protections that significantly limit their options.
A tenant with a disability cannot be evicted without a relocation proposal if their resources are below a certain threshold. The landlord must then propose a suitable solution, under comparable location and price conditions. This obligation also applies to elderly tenants under certain income conditions.
In practice, a landlord who buys a property occupied by a vulnerable tenant must factor this constraint into their calculations. The notice for reclaiming or selling the property becomes a lengthy procedure, sometimes blocked for several years if no acceptable relocation solution is found.

Property management and taxation: unfurnished or furnished rental
The choice between unfurnished and furnished rental is not just about furniture. It determines the applicable tax regime, the duration of the lease, and the conditions for termination.
In unfurnished rental, the lease lasts a minimum of three years (six years if the landlord is a legal entity). The income is declared as property income. In furnished rental, the lease is for one year (nine months for a student), and the income falls under industrial and commercial profits (BIC), with a more advantageous flat-rate deduction under the micro-BIC regime.
Daily management, whether handled directly by the owner or delegated to a professional, involves monitoring rent receipts, annual adjustment of rental charges, and rent revision according to the IRL. The adjustment of charges must occur once a year, with a detailed statement sent to the tenant. Any delay exposes the landlord to disputes that are difficult to resolve.
- Check each year that the revised rent does not exceed the applicable ceiling in tight rental areas
- Keep supporting documents for charges for at least three years after the adjustment
- Anticipate maintenance work to prevent the property from falling into category F or G at the next DPE
The regulatory framework for real estate rental is gradually tightening, with increasingly strict energy requirements and expanded tenant protections. Both landlords and tenants should regularly check the rules applicable to their situation, as a lease signed today will not be subject to the same constraints in five years.
