A mostly old stock
The national condominium registration register (RNIC) records the construction period of 468,674 condominiums (dissolved ones excluded, unknown periods left out).
| Construction period | Condominiums | Share |
|---|---|---|
| Before 1949 | 199,315 | 42.5% |
| 1949 – 1974 | 131,952 | 28.2% |
| 1975 – 1988 | 34,658 | 7.4% |
| 1989 – 2000 | 30,216 | 6.4% |
| 2001 – 2012 | 35,792 | 7.6% |
| 2013 – 2021 | 25,621 | 5.5% |
| 2022 onwards | 11,120 | 2.4% |
More than four condominiums in ten were built before 1949, and more than seven in ten before 1975, that is before the first thermal regulations (1974). These buildings concentrate the challenges of energy renovation, upgrading to standards and structural works.
Older condominiums are also smaller: about 20 units on average before 1949, against about 55 or more for those built between 1949 and 2000.
Heating: individual dominates
| Heating type | Condominiums | Share |
|---|---|---|
| Individual | 471,775 | 79.8% |
| Collective | 87,908 | 14.9% |
| Mixed | 11,819 | 2.0% |
| No heating | 19,881 | 3.4% |
All installations combined, the most cited heating energies are natural gas (62,072 condominiums), electricity (50,128), district heating (18,388) and heating oil (12,155). The latter is due to disappear from shared boiler rooms.
Lifts: one condominium in four
Of 598,465 condominiums where the information is recorded, 164,107 (27%) have at least one lift. A lift is costly to maintain and replace, and weighs on the shared-charges budget.
