Housing is essential for biological development (shelter, inclement weather …), personal (security, well-being, intimacy …) and social (coexistence, neighborhood relations …) and is inseparable from socio-economic progress. : its access is key to achieving sustainable, safe and inclusive cities and societies.

Housing is a fundamental right enshrined in the Universal Declaration of Human Rights and a service of general interest which must be legally secure in terms of its ownership, adapted to the family program, quality, environmentally sustainable, accessible and affordable.

The proper functioning of the housing market is key from many perspectives such as macroeconomic, financial and social. When house prices, especially rental prices, rise:

• Many groups are excluded.
• Others have to bear an excessive burden on their income.
• There is a delay in the formation of households by young people, which, in turn, negatively affects the birth rate.
• Job mobility is hampered.
• Increases residential rental investment, which leads to an increase in house prices.
