How close can a wind turbine be to homes?
In short: There is no nationwide uniform rule. The governing figure is the higher of two values — the flat-rate setback set by state law (where one exists) and the TA Lärm (Technical Instructions on Noise Abatement) noise distance derived from the acoustic calculation. In practice, permitted setbacks usually lie between 600 and 1,500 m.
The two benchmarks
- Flat-rate rule under state law: Some federal states prescribe a fixed minimum setback (e.g. 1,000 m). Bavaria uses the 10H rule.
- TA Lärm noise distance: The acoustic emission prognosis determines the distance from which the night-time noise limits at the home are met — typically 600–1,000 m depending on turbine type and area.
The higher value always applies. Where housing is dense, the noise requirement is usually stricter than the flat-rate rule.
Minimum setback by federal state
| Federal state | Rule (as of 2026) |
|---|---|
| Bavaria | 10H (10 × total height, at 200 m = 2,000 m) |
| NRW (North Rhine-Westphalia) | 1,000 m (opt-out possible for municipalities) |
| Brandenburg | 1,000 m |
| Saxony | 1,000 m |
| Schleswig-Holstein | 400 m + TA Lärm |
| Lower Saxony, Baden-Württemberg, Hesse, Rhineland-Palatinate and others | no flat-rate rule — TA Lärm decides (typ. 600–1,000 m) |

Why does the setback often apply only to residential areas?
The flat-rate rules under state law usually refer to "residential development within the meaning of planning law" — that is, designated residential areas. Individual houses in the outlying area (Außenbereich, undeveloped land outside settlements, e.g. resettler farms) are less protected; there, TA Lärm applies directly.
Frequently asked questions
Is there a nationwide minimum setback?
No. The federal government gave the states an opt-in option for flat-rate setbacks, but did not prescribe a uniform value. TA Lärm remains the governing standard.
What if my house is closer than the minimum setback?
Existing homes enjoy grandfathering (Bestandsschutz, protection of existing rights) — a new turbine must maintain the setback to your house. New construction within the impact zone after the turbine has been permitted has no retroactive claim to protection.
How is the setback measured?
From the base of the turbine mast to the nearest residential development. In the acoustic calculation, the noise source is the hub height.
