Satunnainen

Installing underfloor heating is an increasingly popular choice in both new construction and renovation projects. It offers comfort and energy efficiency, but its installation can also affect building permits. This article discusses how installing underfloor heating affects building permits in Finland.

The need for building permits

The need for building permits depends on many factors, such as the building’s intended use, location and the extent of the renovations. In general, if the installation of underfloor heating changes the structure of the building or affects its safety, a building permit is necessary.

Installation of underfloor heating in a new building

In the case of a new building, underfloor heating can be included in the building permit application. In this case, the plans are checked as part of the entire construction project. It is important that the plans are detailed and contain information about the type of floor heating system, the installation method and possible effects on the building’s structures.

Installation of underfloor heating at the renovation site

The situation can be more complicated in renovation sites. If the installation of underfloor heating requires structural changes, such as dismantling or reinforcing the floor, a building permit is usually necessary. In addition, if the changes affect the building’s energy efficiency or fire safety, these aspects must be taken into account in the permit application.

Contents of the building permit application

The following information must be presented in the building permit application:

  • Plans and drawings showing the installation method and location of underfloor heating.
  • Exploration of the technical characteristics and energy efficiency of the underfloor heating system.
  • Possible effects on the building’s structures and safety.
  • Installation schedule and responsible persons.

Summary

Installing underfloor heating can affect building permits, especially when it requires structural changes or affects the safety of the building. In new buildings, underfloor heating can be included in the building permit application, while in renovation projects the need for a permit depends on the scope of the changes. It is important that the building permit application contains all the necessary information and plans so that the authorities can assess the project’s effects comprehensively.
