The main problem(s)/issue(s) related to RentalCal in France are:
The predominance of natural individual persons as investors in the rental stock.
50% of the private rented housing stock is mixed with other types of occupancy (generally with owner-occupiers). It does not facilitate the decision-making process of the technical renovations.
The French state policies regarding the energy efficiency favors clearly either owner-occupiers or social housing companies not the natural persons. Some tax incentives are not available for individual landlords.
There is clearly a need of information and a technical assistance to support the technical process of the improvement of the energy efficiency.
Despite the regulation which allows the sharing of the energy savings between the landlord and its tenant in case of building works, the tenants’ high mobility does not incent to a tenant/landlord sharing of the energy savings as 60% of the tenants have a max length of residency of four years. To overcome this obstacle a strong social engineering is needed as 70% of the private rental housing stock consists in multi families buildings governed by the voting rules of the majority.
