Here's the current figure and what to confirm. Berlin’s building law is the **Bauordnung für Berlin (BauO Bln)**, currently in force. **Minimum room height (lichte Raumhöhe): 2.40 m**, set in **§47(1) BauO Bln**. This is a **very recent figure** — Berlin reduced its minimum from 2.50 m to 2.40 m around **21–22 December 2024** (sources differ by a single day on the exact date), so confirm you’re working from the current text rather than an older reference that still quotes 2.50 m. In a roof space, the figure reduces to **2.30 m** over at least half the room’s floor area. Your LBO also sets boundary setbacks (Abstandsflächen), guard/parapet (Umwehrung) heights, and permit-free (verfahrensfrei) thresholds for garages and carports — none of these were independently confirmed for Berlin, so confirm them directly in the [BauO Bln text on gesetze.berlin.de](https://gesetze.berlin.de/) before you build to a number. ## Related - [**German building rules hub**](https://www.chippy.tools/building-codes/de/) — how the national DIN layer and the 16 Länder’s own building law fit together. - [**Minimum room heights across Germany**](https://www.chippy.tools/building-codes/de/rooms/minimum-room-heights/) — why there’s no single national figure. - [**German stair & guard rules**](https://www.chippy.tools/building-codes/de/stairs/stair-and-guard-requirements/) — the DIN 18065 numbers plus the Land-by-Land guard-height picture. ## Adoption status Adopted Current code in force Bauordnung für Berlin (BauO Bln), as amended Dec 2024 Next edition Not announced Adoption / transition BauO Bln room height dropped from 2.50 m to 2.40 m in a very recent late-2024 amendment (§47(1)).
