In 2026, rental obligations change and owners who do not comply with these new requirements are exposed to sanctions and litigation, which underlines the importance of knowing the rules well.
Firstly, the Climate and Resilience law puts the subject of DPE (energy performance diagnosis) once again at the heart of the concerns of landlords. Indeed, from 2026, all housing classified F and G at the DPE will have to be renovated to reach at least class E. This requirement particularly affects old homes, small areas and those heated with electricity. Their classification could change with the new method of calculating the DPE, which includes a revised energy coefficient. In this context, keeping your diagnosis up to date becomes essential.
In the event of non-compliance with these energy obligations, the owner is exposed to rent freeze as long as the accommodation does not comply with fines which can reach several thousand euros, as well as litigation with tenants, which could result in reduction in rent or a forced compliance.
To precisely determine the work to be carried out, a energy audit may be required. In this context, real estate experts strongly advise owners to plan now insulation, heating and windows. But the rental obligations planned for 2026 are not limited to these energy measures alone and also concern the documents, diagnostics and local rules to be respected.
Diagnostics and information for the tenant: no approximation allowed
In 2026, all documents attached to lease must be up to date and complete. This includes the mandatory diagnostics (DPE, gas, electricity, state of natural and technological risks), the certificates of conformity of installations (heating, ventilation, plumbing, fire safety) as well as precise information to be transmitted to the tenant (exact rent, actual surface area, detailed description of the accommodation).
Added to this are the specific requirements of certain municipalities or communities, relating to ventilation, hygiene, fire safety, the conformity of installations, but also the management of waste and specific equipment in old housing. Any failure may be considered a lack of decencyexposing the owner to financial penalties or litigation. To protect themselves against these risks, informed investors will therefore take care to archive all documents and supporting documentswhile anticipating the necessary work to stay compliant and avoid sanctions, which can range from a simple fine to a temporary ban on renting.
