Bavaria’s building law is the **Bayerische Bauordnung (BayBO)**, currently in force. Bavaria diverges from the Musterbauordnung model more than most Länder, on several figures a chippy actually uses. **Minimum room height (lichte Raumhöhe): 2.40 m** where it applies, per **Art. 45(1) BayBO** — but Bavaria **exempts an ordinary one- or two-family house (Gebäudeklasse 1 & 2)** from any fixed minimum room height at all. In a roof space, the figure that does apply reduces to **2.20 m** over at least half the room’s floor area. Two other Bavaria-specific figures are confirmed. **Boundary setbacks (Abstandsflächen)**: the default depth factor is **0.4 × wall height** (minimum **3 m**), since a **1 February 2021** reform — per **Art. 6 BayBO**. Some categories and larger cities apply different depths — confirm against **Art. 6 BayBO** directly. **Permit-free garages**: a garage up to **50 m²** floor area (or 75 m³ if it has no habitable rooms, toilet or hearth) and up to **3 m** wall height doesn’t need a building permit, per **Art. 57 BayBO**. **Guard/parapet (Umwehrung) height is the one figure Bavaria’s law doesn’t give a number for at all.** Art. 36 BayBO only requires a guard be “ausreichend hoch und fest” — sufficiently high and sturdy — leaving the actual height to accepted technical rules rather than statute text. Confirm your builder’s guarding against current technical guidance, and check [BayBO on gesetze-bayern.de](https://www.gesetze-bayern.de/) for anything above before you rely on it. ## 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 Bayerische Bauordnung (BayBO) Next edition Not announced Adoption / transition BayBO exempts an ordinary 1–2 unit house from any fixed room-height minimum and gives no number for guard height at all.
