Features of Installing Climate Control Systems in Residential Buildings
As summer ends, many residents of Spain consider buying and installing an air conditioner in their apartment. However, before starting any work, it is important to thoroughly review the legislation regulating the use of shared property. In particular, the Law on Horizontal Property (Ley de Propiedad Horizontal) includes several restrictions regarding changes to the building’s exterior and the use of façades.
Legal Nuances and Collective Decisions
According to current regulations, any work affecting the façade requires approval from other owners. The law permits changes inside the apartment if they do not impact the safety, structure, or appearance of the building. The façade, as a common area, cannot be altered at the discretion of one resident. To place an external unit of an air conditioner on the façade, a homeowners’ meeting must give its approval. Exceptions are possible only if the installation does not disrupt architectural harmony or infringe on the rights of other residents.
Alternative Options and Expert Recommendations
Property managers advise considering alternative ways to install equipment. For example, it is allowed to place air conditioning units on private terraces or in internal courtyards, provided these areas are assigned to a specific apartment and do not belong to communal property. In any case, neighbors must be informed about planned changes. Experts also recommend choosing models that do not require major construction work and do not affect the building’s exterior appearance.
Liability for violating the rules
Failure to comply with established requirements can lead to serious consequences. If equipment is installed without consent, the homeowners’ association may require its removal. If the request is denied, the matter can be taken to court, where decisions are usually made in favor of the majority of residents. In certain cases, especially in historic districts, substantial fines of up to €20,000 may apply. Complying with the law helps avoid not only financial losses but also conflicts with neighbors.
