Containers and planning permission – everything you need to know
The answer depends on several key factors: the length of time the container is to be used for, its intended purpose, and how it is to be situated on the plot. In this article, we discuss the current provisions of building law (in particular Article 29(1) and (1a) of the Act), the formal procedures, as well as specific cases in which a permit may be required. We also cite examples of the latest case law – including the judgment of the Provincial Administrative Court in Warsaw of 15 November 2022 (case no. VII SA/Wa 1044/22) – which illustrate how building control authorities interpret the issue of containers in practice.
When is a notification sufficient, and when is a planning permission required?
The Building Act sets out quite precisely the situations in which a container may be erected solely on the basis of a notification – without the need to obtain a planning permission. This applies to cases involving:
● temporary structures not permanently fixed to the ground,
● use not exceeding 180 days,
● structures intended for relocation or demolition.
In accordance with Article 29(1)(12) of the Building Act, if a container is to remain on the plot for longer than 180 days, it is necessary to obtain planning permission – even if it is not permanently fixed to the ground. Furthermore, if it is connected to utilities (electricity, water, sewerage), it will be treated as a permanent structure.
A house made from containers – planning permission is always required
What is the legal situation when it comes to a house made from shipping containers? Well, in many cases, planning permission proves to be essential – especially if the property is to serve as a permanent residence. Doubts often arise because, whilst such a house may look unassuming from the outside, under the regulations it is treated in much the same way as a conventional property. In practice, this means that a container house requires a building permit based on the same regulations and requirements as a traditional detached house. If you are considering building a container home, you must bear in mind that:
- a planning permission for a container home is always required,
- it is necessary to obtain planning conditions or a local development plan,
- the design must include the following installations: plumbing, heating and electrical,
- the property must meet the standards for residential buildings.
Even if a container home is not permanently fixed to the ground, its intended use and duration of occupation are decisive factors in assessing whether a building permit is required. Importantly, the mere absence of foundations does not mean that the formalities can be overlooked. If the container is to serve as a home and will be used on a permanent basis, the need to obtain planning permission becomes clear.
Office container – do you need a permit or is a notification sufficient?
Many investors wonder whether a planning permission is always required for an office container. The answer is not clear-cut – it all depends on specific technical parameters, such as the intended period of use or how the utilities are connected. It is therefore worth looking into this issue before placing the container on the plot.
In the case of office containers, three factors are of key importance: the duration of use, the method of installation and access to utilities.
In practice, this works as follows:
- use for up to 180 days, without foundations and without utility connections – a simple notification is sufficient,
- longer-term use, connection to other modules or connection to utility networks – requires a building permit.
According to current case law, a container that is fitted with installations and connected to external networks is no longer treated as a temporary structure and is automatically subject to the full administrative procedure.
Storage and utility containers – exceptions and restrictions
Under the Building Act, it is possible to erect an outbuilding of up to 35 m² without the need to obtain planning permission. However, several specific conditions must be met:
● the building must be single-storey and detached,
● it must be used exclusively for domestic purposes (e.g. as a tool shed),
● there must be no more than two such buildings for every 500 m² of plot area.
It is worth bearing in mind that even if a container meets the above requirements, it must still comply with the local town planning scheme. This is an often-overlooked but crucial element of any development.
Container-based site facilities – when is a permit not required?
In accordance with Article 29(1)(24) of the Building Act, no planning permission is required for the construction of temporary structures:
● situated on a building site,
● used during the course of a development project,
● serving the specific construction project directly.
Provided that the main development has a valid building permit, containers (staff, storage and office containers) may be erected without any additional formalities.

Containers and planning permission – a summary of the formal requirements
Although the regulations can be rather confusing, a well-prepared list of typical scenarios allows you to work out fairly quickly whether a simple notification will suffice in a given case, or whether a formal planning permission will be required. It is worth bearing in mind, however, that every situation has its own nuances – and these can change everything. That is why it is so important to analyse planning documents thoroughly and, ideally, to look at the whole picture not only from the perspective of the regulations but also in terms of practical application. Because a container and a planning permission are not just a question of the type of structure. What also matters is how it is used and how long it will remain in a given location. And the difference between ‘temporary’ and ‘long-term’ can mean a completely different procedure
Depending on the type of container, its intended use and duration of use, different regulations apply regarding notification or obtaining planning permission. Below, we present a summary of the most common scenarios in the context of the current Building Act.
| Container type | Temporary (max 180 days) | Permanent (more than 180 days) |
| Office container |
Notification (Article 29(1)(12)) |
Planning permission required |
| Apartment container | Application (if temporary, without connections) | A planning permission is required (Article 29(1a) and (4)(1)) |
| Storage container | Application (if it meets the criteria for temporary status) | Planning permission required |
|
Farm building < 35 m² |
Lack of a licence (Article 29(1)(2)(c)) | No licence* |
|
Construction site facilities |
Lack of a planning permission (as part of a building project) | No planning permission (as part of the same development) |
* No planning permission is required, provided that the number and size of the buildings do not exceed the limits set out in Article 29(1)(2)(c) (one building for every 500 m² of plot area).
What should you bear in mind?
- If the container is to be used for a short period and without any installations, a simple notification is usually sufficient.
- If the module is to be used for longer than 180 days, will be connected to utilities or used as a dwelling – a planning permission will almost always be required.
- Container homes are treated in the same way as detached houses – they require full documentation.
- In the case of site facilities – if they form part of an approved development – a planning permission is not required.
- Even the absence of foundations does not exempt you from the formalities if the intended use indicates a permanent structure.
Each case requires individual analysis – including in terms of the local development plan and local regulations.
