Swedish tenants may be able to report persistently high indoor temperatures to their landlords. Specifically, temperatures exceeding 26 degrees Celsius can be reported as a fault. However, this guidance does not apply during periods of exceptionally hot weather, acknowledging natural fluctuations. The regulation aims to ensure habitable living conditions within rental properties. Landlords are expected to address the issue when temperatures remain consistently above the specified threshold. This rule provides a framework for resolving heat-related complaints in rented accommodations. The exception for extreme weather events prevents unnecessary intervention during temporary heatwaves.
