The first thing to do is to inform the community that we are going to install a charging point. Informing them is sufficient, since thanks to the Horizontal Property Law, the installation does not have to be submitted for approval by the owners' meeting, but it is sufficient to notify the administrators in writing. For the installation of a charging point in a communal garage, there are mainly two types of configuration:
1: The garage is located in the same community as the dwelling.
It is common for the garage to be located in the basement of the residential building. In this case, the regulations allow a cable to be laid from the meter of the dwelling (note that the regulations require it to be from the meter) to the parking space. This is the most optimal solution, as it allows the electricity supply point (and the bill) to be shared by the house and the charging point (emulating a single-family house).
2: The garage is a different property (different community).
In this case you will have to apply to the distributor for a new supply point (with a different meter) and you will be forced to have a different electricity bill.
In both cases, there is a third way, which is to feed the charging point from the garage supply point (the one that feeds the communal areas). This requires the installation of a secondary meter, so that the community can pass on the electricity bill on a monthly basis. Although this is the most optimised way (especially for a future with many charging points), in practice it is hardly used, as it requires the community to agree, as well as needing a platform to manage the costs to be passed on to each neighbour.
