1. What are the typical actions to be taken on the building envelope that I manage?
The most common actions include replacing windows and facade joinery, insulating the facade (either from the outside or the inside), and insulating and waterproofing the roof. Measures to eliminate dampness caused by condensation or rising damp may also be carried out.
2. If we install a photovoltaic system on a building, can the energy generated be shared with the neighbors?
Absolutely. The law allows this through predefined distribution coefficients that are established when the installation is legalized. The key requirement is that the building has available space for the system.
3. Some neighbors don’t want photovoltaic panels installed on the roof. What can we do?
The Horizontal Property Law is clear: to install photovoltaic panels for community consumption, 50% of the neighbors must agree, and in that case, the cost must be shared among all neighbors (whether they agree or not).
If it is for private use by some neighbors, at least one-third of the neighbors must agree to allow the use of the roof (they don’t have to participate in the self-consumption, just give consent). In this case, the rest must allow it, provided that the installation is paid for by those who will benefit from it, and that they allow other neighbors to join under predefined conditions if they wish to do so later.
4. I live in the top-floor apartment of a multi-storey community. Can I install panels on the roof?
You will still need to request permission from the community. According to the Horizontal Property Law, at least one-third of favorable votes are required to carry out the installation, and the community is not obliged to cover any of the related costs.
5. I live in a multi-storey community. Can I install panels on the roof if the top-floor neighbor gives me permission?
Permission must be requested from the community. According to the Horizontal Property Law, at least one-third of favorable votes are required to carry out the installation, and the community is not obliged to cover any of the related costs.
6. I live in a multi-storey community. How many neighbors must agree in order to install panels? If one neighbor opposes, can we still install them if several of us are in favor?
If it’s for private use by some neighbors, at least one-third of the neighbors must agree to the use of the roof (they don’t have to participate in self-consumption, just consent to the use). In that case, the rest must allow it, provided that the benefiting neighbors pay for the installation and allow others to join later under predefined conditions.
If a neighbor opposes but represents less than two-thirds of the community, the installation can still go ahead.
