From 1 August 2025, another package of amendments to the Building Act is effective, which aims to speed up and simplify building procedures, reduce administration and promote digitisation.
One of the key innovations is adjustment of the range of so-called small buildings . Photovoltaic systems on roofs will now be considered small-scale construction up to 100 kW instead of the current 50 kW. Some connections and parts of technical infrastructure will also fall into this category. However, conditions such as distance from the property boundary must be observed and all other legislation, including fire safety or monument protection, must be complied with.
There is also a significant change in simple buildings. Documentation for the implementation of these constructions will not have to be as extensive as before and in many cases the obligation of approval will be eliminated – a simple notification of the completion of the construction to the building authority will be sufficient. This group now includes, for example, domestic sewage treatment plants, wells or stand-alone photovoltaic installations up to 250 kW. In addition, the administrative fee for wells and wastewater treatment plants is reduced from CZK 10,000 to CZK 5,000.
The amendment also introduces the obligation to record selected data on transport and technical infrastructure in the digital technical map of the region. The builder will have to provide a filing identification number as proof of recording. This will link the construction procedure with the digitisation process, which is one of the main objectives of the law.
Another area of change is energy requirements and infrastructure for electromobility. As of 2027, non-residential buildings with more parking spaces will have to have at least one charging point or ready cabling for charging. Requirements for intelligent control systems for heating, cooling or lighting in buildings with higher consumption are also being phased in.
These changes are followed by the digitalization of the construction procedure via the Builder’s Portal. This will allow online submission and monitoring of the proceedings, which should lead to more transparent communication with the builder. Another important point is the sharing of a single electronic file between authorities. The transitional period will last until 2027 and includes the possibility of filing some documents in paper form. Digitisation is intended to increase the efficiency, transparency and accessibility of services, although its introduction will involve a gradual adaptation of the authorities and builders.
Overall, the amendment aims to simplify and speed up permitting processes, reduce the administrative burden and increase the digitalisation of the construction industry, while responding to current needs in the energy and environmental sectors.
