Does a container need a building permit? Germany, North Rhine-Westphalia
In Germany, North Rhine-Westphalia the governing measure is gross volume. A container whose gross volume stays within 30 m3 falls into the simplified route and is handled as a full permit. Above that line the full building-permit procedure applies. The basis is Bauordnung für das Land Nordrhein-Westfalen (Landesbauordnung 2018 - BauO NRW 2018), § 62 Abs. 1 Nr. 1, in the version of 2024-01-01. The statute is quoted word for word further down this page, in the original language and in translation, so you can check the figure without leaving the site. The authority to contact is Untere Bauaufsichtsbehoerde.
What are the thresholds?
| Measure | Value | When this number applies | Provision |
|---|---|---|---|
| Gross volume, no habitable rooms | 30 m3 | The strictest limit of the four verified German states and the only one that sits below a standard 20 ft container. A 20 ft unit is 38.27 m3 and crosses the 30 m3 line; only a 10 ft at 17.78 m3 stays under it. The no-habitable-rooms condition and a 3 m mean wall height apply on top. | § 62 Abs. 1 Nr. 1 |
| Minimum boundary setback | 3 m | The depth of the setback area is 0.4 H, at least 3 m; in commercial and industrial zones 0.2 H suffices and in core zones 0.25 H, but at least 3 m in every case. For a container the 3 m floor governs. | § 6 Abs. 5 Satz 1 |

Do you need a permit or is a notification enough?
In North Rhine-Westphalia a normal container sits above the procedure-free line, so a building permit is the usual route. Only a small unit up to 30 m3 without habitable rooms and with a mean wall height up to 3 m falls inside the exemption. The practical consequence: a 20 ft container needs a permit here although it does not in Bavaria or Saxony.

Who do you contact?
Untere Bauaufsichtsbehoerde. The lower building supervisory authority of the municipality or district. The governing statute is the North Rhine-Westphalian building code, not a federal act.
What documents will you need?
- A building permit application (Bauantrag) filed with the competent building supervisory authority, because a normal container falls outside the exemption.
- A gross-volume and mean-wall-height calculation showing the position against the 30 m3 and 3 m limits.
- Evidence of conformity with the Bebauungsplan where one exists for the plot.
- A site plan with the § 6 setback areas.
How do the neighbouring jurisdictions compare?
| Jurisdiction | Built-up area | Gross volume | Height | Boundary setback | Do you need a permit or is a notification enough? | Does the exemption cover an office container? |
|---|---|---|---|---|---|---|
| Germany, North Rhine-Westphalia | The statute states no fixed figure | 30 m3 | The statute states no fixed figure | 3 m | Full permit | No |
| Slovakia | 50 m2 | The statute states no fixed figure | 5 m | 2 m | Notification | Yes |
| Czechia | 40 m2 | The statute states no fixed figure | 5 m | 2 m | Full permit | Yes |
| Poland | The statute states no fixed figure | The statute states no fixed figure | The statute states no fixed figure | Not yet verified | Notification | Yes |
What to watch out for
- This is the strictest of the four verified German states and also the most populous. The 30 m3 line sits below a standard 20 ft container, which is 38.27 m3 on the ISO 668:2020 external dimensions. Only a 10 ft unit fits under it. Carrying Bavaria’s 75 m3 across to North Rhine-Westphalia is wrong by more than a factor of two.
- The version the portal presents as newest applies only from 1 September 2026 and was not yet law at the time of verification. We therefore cite the version actually in force, which states its own window: Gültig ab 01.01.2024 and Gültig bis 31.08.2026. After 31 August 2026 the text has to be retrieved again.
