Container on a plot - notification or building permit?

That is a costly mistake. A container placed without the required notification or permit is an unauthorised construction (samowola budowlana). Such a container can be seen from the road and from the neighbour's property, and the costs of legalisation or an ordered removal are usually many times higher than the cost of completing the formalities at the start.

Below we explain what decides whether a notification is enough, when a building permit is needed and what to check before the container stands on the plot. The text concerns containers for storage, not residential ones. The rules described are Polish, because that is where the listings on Maszbox.pl are located.

First check: does the container stand on a building site?

If you are building a house and the container serves as site facilities, stands on the building site and only for the duration of the work, different rules apply: you need neither a notification nor a permit. We describe this in the article container on a building site. The rest of the text concerns a container standing on a plot without an ongoing build.

A container for less than 180 days: notification

The Polish Construction Law allows a temporary structure that is not permanently fixed to the ground to be put up on the basis of a notification (Article 29(1)(7)). The condition: the structure must be dismantled or moved elsewhere within 180 days of the start of construction.

In practice this means that:

• the container must not stand on a foundation; placing it on blocks or slabs is usually not treated as a permanent connection to the ground,
• it must be planned as temporary from the start. If you already know when placing it that it will stay longer than 180 days, a notification on this basis is not the right route,
• you file the notification at the county office (starostwo) or the office of a city with county rights, and you place the container only once the office has not raised an objection within the statutory time limit.

This procedure suits a container rented for a few months, for example during a renovation. You will find offers in the listings of containers for rent.

A container for more than 180 days: building permit

If the container is to stand for longer than 180 days or permanently, a building permit is needed. This also applies to a container that is not fixed to the ground.

If the container was notified as temporary and it turns out it will be needed for longer, you can apply for a building permit before the 180 days are up (Article 37a of the Construction Law). This way you do not have to remove it. The application must be filed before the deadline, not after it.

If you are buying a container to stand at your place for years, be prepared for the permit procedure or check the option described in the next section. You will find sale listings in the containers for sale category.

Can a container be a utility building on a notification

The Construction Law allows small utility buildings to be put up on a notification. In some situations a container can also be notified in this way, but only if it has the features of a building, among other things a foundation, walls and a roof, and falls within the limits on floor area and the number of such buildings on the plot. Whether your container qualifies is up to the office, so ask at the county office or an architect before choosing this route.

What to check before placing the container

• The local zoning plan or, if there is no plan, the zoning conditions. The plan may restrict what can be built on your plot.
• The distance from the plot boundary. Ask the office what distances apply in your case before choosing the spot.
• Who files the notification. This is usually the investor, meaning the person on whose plot the container will stand, also when the container is rented from a listing with delivery. Confirm this at the office and agree the delivery date with the advertiser so that the container arrives after the formalities are completed.
• Location and size. If you are still choosing a container, see what container size to choose, and make sure it will fit on the plot together with access for a truck with a crane.

What happens if you skip the formalities

A container placed without the required notification or permit, or left in place after 180 days without a permit, is an unauthorised construction. The building control authority may then conduct legalisation proceedings or order the container to be removed. In both cases it costs more and takes longer than completing the formalities before placing it.
