Construction work in the house or in the neighborhood annoys many residents. When these must be announced – and when a rent reduction is justified.

Modernization measures in or on the house must always be announced by the landlord three months in advance, in writing. If there are modernization measures in the apartment, there is a risk of a rent increase - but this is only permitted in certain cases. The usual local rest times apply to craftsmen - primarily between 10 p.m. and 6 a.m., but the building use regulations distinguish between residential, commercial and mixed areas. There is no afternoon rest. And if the construction workers start work in front of the bedroom at 7 a. m., residents usually have to live with it. However, according to the general administrative regulations for protection against construction noise, the continuous sound level is limited to a maximum of 55 decibels. The noise protection rules also apply here and building owners and companies must adhere to them. It is usually different, as construction site noise usually has to be tolerated.
