Many citizens seek to optimize electricity consumption, taking advantage of the cheapest time slots, which are usually between 2 PM and 5 PM and during the early morning. This practice, while it can reduce the electricity bill, carries risks, especially if carried out at night, due to the noise it can generate.
The Horizontal Property Law (LPH) establishes that owners must respect the use and enjoyment of other people's homes, avoiding activities that may cause disturbances. Article 7.2 of the LPH prohibits activities that contravene general provisions on annoying, unhealthy, harmful, dangerous, or illicit activities.
Furthermore, Law 37/2003 on Noise regulates acoustic pollution and allows city councils to set decibel limits. Municipal ordinances complement this law, determining silence hours and maximum permitted noise levels. Generally, during nighttime hours, limits are stricter, and noise cannot exceed 25-30 dBA.
A washing machine can reach 50 dBA, and during spinning, some models can emit up to 72 dBA, far exceeding the limits established for the night. If a neighbor persists in the disturbing behavior, the community can file a cessation lawsuit. Administrative fines, which vary by community, usually range around 300 euros, but can reach up to 3,000 euros in serious or repeated cases.
