WHY IS A BUILDING PERMIT OR NOTIFICATION GENERALLY NOT REQUIRED FOR A SUPER ARKTIK® MOBILE HOME – EVEN AFTER CONNECTION TO UTILITIES?
A common question regarding mobile homes is whether a building permit or at least notification to the building authority is required, especially in cases where the mobile home is connected to electricity, water, or sewage.
In practice, year-round SUPER ARKTIK® mobile homes are generally considered not to require a building permit or notification, even after being connected to utility networks. This conclusion follows from their technical nature and from the interpretation of the relevant provisions of the Building Act. The following text summarizes the general framework on which these considerations are based.
SUPER ARKTIK® mobile home as a residential vehicle
SUPER ARKTIK® mobile homes are manufactured in accordance with the technical standard STN EN 1647+A1 as residential vehicles. For this reason, they are generally not considered buildings within the meaning of the Building Act.
According to Section 2(1) of the Building Act, a structure is considered a building if it is:
- connected to the ground by a permanent foundation, or
- connected to the ground in another manner.
At the same time, Section 2(1)(d) of the Building Act states that, for buildings, connection to utility networks (e.g. electricity, water, sewage) is also considered a connection to the ground.
However, these provisions apply to buildings, while the Building Act does not specifically regulate the legal status of residential vehicles.
Assessment as a minor structure
In practice, a building authority may also assess a mobile home under the regime of a so-called minor structure. According to Section 2(4)(a) of Building Act No. 25/2025 Coll., a minor structure also includes an assembled product that:
- does not exceed a built-up area of 50 m²,
- does not exceed a height of 5 m.
SUPER ARKTIK® mobile homes meet these parameters. Under the Building Act, minor structures are generally exempt from the obligation to obtain a building permit or submit a notification, unless the law explicitly provides otherwise.
Connection to utility networks and its significance
A frequent question is whether the mere connection of a minor structure to utility networks changes its legal status.
The Building Act, in Section 18(3), provides that notification to the building authority is required only in cases explicitly stated by the law. At the same time, the law does not explicitly state that connecting a minor structure to utility networks:
- is automatically considered a connection to the ground, or
- creates an obligation to notify or obtain a building permit.
For this reason, in practice it is often concluded that connection to utilities alone does not change the legal regime of a minor structure. However, the specific assessment may depend on the individual circumstances of the case.
Distinction between a building and a minor structure
The Building Act clearly distinguishes between:
- buildings (Section 2(1)),
- minor structures (Section 2(4)).
For buildings, the law explicitly states that connection to utilities constitutes a connection to the ground. For minor structures, however, no such provision exists. This distinction must be respected when interpreting the law, as obligations under building law must always have an explicit legal basis.
Informative summary
Based on the above, it is generally assumed in practice that:
- a SUPER ARKTIK® mobile home is not a building within the meaning of Section 2(1) of the Building Act,
- it may meet the characteristics of a minor structure under Section 2(4)(a),
- its connection to utility networks does not in itself usually change its legal status,
- a building permit or notification is usually not required.
A building permit or other procedure is typically required mainly in cases where the owner applies for the assignment of a house registration number, or where specific circumstances lead the building authority to a different legal assessment.
