The building owner/ landlord is liable in case of damage in the event of a powercut, unless the obligation to maintain safety systems has been outsourced or delegated.
In case of a power failure the underground garage or the staircase is pitch-dark and tenants could not only get panicky, but also stumble and hurt themselves.
The law requires that the emergency lighting must be controlled regularly to ensure that it functions properly in case of emergencies.
We’re happy to support you.
