Wind farm near a property in Germany: rules and distances
Buying near a German wind energy area: the 2H rule, Bavaria's 10H, noise and shadow limits, where to see the plans and how to object.
On this page
Germany is in the middle of a mapping exercise that will decide, for the next two decades, where wind turbines may stand. Every federal state has a legal quota of land it must set aside for wind energy by the end of 2027 and a larger one by the end of 2032. Regional planning bodies are drawing the lines now, and many of them run a few hundred metres from villages.
If you are buying a house or a building plot in the German countryside, especially from abroad, two things follow. A field that looks empty in the listing photos may be inside a designated wind energy area. And the distance rules you may have read about, such as Bavaria's famous "10H", have been cut back since 2022, so the protection you expect may not be there.
This guide explains which distances are law and which are planning choices, how to find the maps yourself (with the German words to type into the search box), what noise and shadow limits a wind farm must meet, what the evidence on house prices says, and how a non-resident can take part in the procedure. It is a pre-purchase screen, not legal advice.

Why the maps are being drawn now
Under § 3 WindBG each state must designate at least the share of its territory listed in column 1 of the Act's annex by 31 December 2027, and the share in column 2 by 31 December 2032. For Bavaria the annex lists 1.1% and 1.8%; for Hesse 1.8% and 2.2%. For Lower Saxony, where the Hannover region lies, the figures are 1.7% and 2.2%.
The states pass these targets down to regional planning. A useful example is the Region Hannover in Lower Saxony. Its regional assembly adopted the wind energy chapter of the regional plan (Sachliches Teilprogramm Windenergie 2025) on 1 April 2025, and it entered into force with the official gazette of 14 August 2025. It designates 40 priority areas covering about 5,368 hectares, which the region gives as 2.34% of its territory. Working backwards, 5,368 ha ÷ 0.0234 puts the region at roughly 229,000 ha. A presentation by the town of Burgdorf records that 1.02% counts towards the region's target, against a requirement of 0.63%; that figure comes from the town, not the region.
Two paragraphs of § 249 BauGB change what a neighbour can expect:
- § 249(1) BauGB switches off the old mechanism (§ 35(3) sentence 3 BauGB) that let municipalities concentrate turbines in a few zones and keep the rest of the countryside free.
- § 249(2) BauGB says that once a state or region has met its quota, turbines outside the designated areas become ordinary projects under § 35(2) BauGB, which in the outer area are normally not approvable.
So the map cuts both ways. Far from any designated area, in a region that has met its target, a new turbine next door is unlikely. Inside or near a designated area, turbines are expected and the planning debate is over. Whether your region has met its target is stated by the regional planning body or in the plan's explanatory report.
The numbers that decide distance
You will hear distances from 400 m to 2,500 m. They come from different rules with different force.
The regional plan's buffer. Planners keep designated areas a set distance from homes. The Region Hannover's own Q&A on the plan gives 800 m from settlements and 600 m from isolated houses and small clusters in the outer area; the Ostwürttemberg region in Baden-Württemberg used 1,000 m from settlement areas in its 2025 update. These distances decide where the area ends. They are not a right you can enforce outside the plan.
2H, the federal rule. § 249(10) BauGB says the visually oppressive effect does "as a rule" not stand in the way of a turbine if the distance from the centre of the tower base to a permissible residential use is at least twice the turbine's height. Height means hub height plus rotor radius.
10H, Bavaria only. Article 82 of the Bavarian Building Code (BayBO) keeps the ten-times-height rule, but with large exceptions since November 2022 (see below).
State minimum distances. Bavaria is not the only state that has had its own minimum distances to homes, and several states have changed their rules since 2021. Ask the county's environmental protection authority which distance, if any, applies to your plot.
Noise and shadow. No fixed distance; the turbine must meet limits at your house, which in practice decides how close it can be.
Three words in § 249(10) a buyer should read twice
- permissible residential use: the distance is measured to where housing is allowed, not only to an existing house. An empty plot in a residential development plan counts.
- centre of the tower base: not the blade tip, not the edge of the designated area. Towers usually stand some way inside the area.
- as a rule: below 2H nothing is automatic; the authority checks the individual case. Before the statute, German courts worked with a scale: under 2H usually oppressive, over 3H usually not, in between a case-by-case call. Expert reports in current permit files in North Rhine-Westphalia and Lower Saxony still quote that scale.
The Bavarian Higher Administrative Court (VGH München, decision of 17 July 2025, 22 AS 25.40003) added that when several turbines together are said to be oppressive, only existing turbines and those applied for at the same time count. Turbines that a developer might add later do not.
A worked example with a modern turbine
Assume a turbine with a 166 m hub and a 168 m rotor. These are illustrative figures; the real ones are in the permit application.
| Measure | Calculation | Result |
|---|---|---|
| Height under § 249(10) | 166 m + 84 m | 250 m |
| 2H | 2 × 250 m | 500 m |
| 3H (older case law) | 3 × 250 m | 750 m |
| 10H (Bavaria, outside wind areas) | 10 × 250 m | 2,500 m |

Now place a farmhouse in the outer area of the Region Hannover 600 m from the edge of a priority area, if the draft buffer applies. If the tower stood right on the edge, the distance would be 600 m, or 2.4H. If it stands 150 m inside the area, 750 m, or 3H. A house in a village 800 m from the edge is at least 3.2H away. On the visual test alone, such a turbine would be hard to stop.
The same house in Bavaria, with no wind energy area nearby and none of the exceptions applying, would be protected by 2,500 m. The moment the regional planning association designates an area, that protection disappears inside it.
Bavaria: what is left of 10H
The Bavarian law of 8 November 2022 (GVBl. 2022 p. 650), in force since 16 November 2022, kept 10H as the starting point in Art. 82(1) BayBO and carved out three layers:
- Six case groups in Art. 82(5) BayBO where 10H does not apply.
- For those groups, Art. 82a BayBO sets a flat 1,000 m from homes, whatever the turbine height.
- Art. 82b BayBO, in force since 31 May 2023, says neither 10H nor the 1,000 m applies inside wind energy areas within the meaning of § 2 no. 1 WindBG.
If you were told "Bavaria has 10H, so you are safe", ask the seller or the municipality one question: is there a wind energy area or a regional plan draft within 2.5 km?
Where to see the plans yourself
You do not need German to find the maps, only the right search terms.
- Regional plan. Search for Teilplan Windenergie or Teilprogramm Windenergie plus the region's name. Check the status label: Entwurf (draft), Satzungsbeschluss (adopted), in Kraft (in force). The Region Hannover lists all three stages separately on its page for the 2025 plan.
- Municipal plan. Search Teilflächennutzungsplan Windenergie plus the town. Göttingen, for example, tested a 522 m distance to housing in its preliminary draft and later added an extra buffer to reach 800 m.
- Permit files. The states publish environmental-assessment files on uvp-verbund.de (Lower Saxony: uvp.niedersachsen.de). Search the municipality's name. You will find noise forecasts, shadow flicker calendars and reports on the visually oppressive effect. Districts also publish granted permits; the Paderborn district does so under the heading Bekanntmachungen § 21a 9. BImSchV.
- Marktstammdatenregister. The Federal Network Agency's register of generating units. Use the Erweiterte Einheitenübersicht (extended unit overview), filter by municipality or postcode and energy source Wind, and look at Betriebsstatus: In Planung (planned), In Betrieb (operating), Dauerhaft stillgelegt (decommissioned). Operators have one month after commissioning to register, so the latest month is incomplete, and "planned" is the operator's own entry, not a permit.
In Bavaria, the state's Energieatlas Bayern adds maps and explanations, including how shadow flicker is simulated.
The planning layers, whether the plot sits in the outer area and nearby protected areas are all in a GrundCheck report for the parcel, each with its source and date.

Noise and shadow flicker: the limits at your window
Noise. Wind farms are assessed under the TA Lärm. Its night-time limits (no. 6.1, outside buildings) are 35 dB(A) in purely residential areas, 40 dB(A) in general residential areas and 45 dB(A) in mixed and village areas. An isolated house in the outer area has no line of its own in the table. The value the authority applies to your house is in the noise forecast filed with the application, listed by receptor point; read that line before you buy.
Shadow flicker. There is no statute, only guideline values. The Bavarian Environment Agency treats up to 30 hours per calendar year and 30 minutes per day, measured at 2 m height, as not a significant nuisance. These figures assume the worst case: sun shining from dawn to dusk and the rotor always facing it. In practice turbines carry an automatic shutdown. In the shadow report for the Aalen-Waldhausen wind farm in Baden-Württemberg, some houses exceeded the worst-case values (for example 30:21 hours a year and 47 minutes a day), so the turbine was fitted with a shutdown that cuts in at 8 hours of real shadow a year; the expected real figure was just over 5 hours.
Read the shadow calendar in the permit file for the point closest to your house: it shows the months and times of day affected. Houses east or west of a turbine get flicker in the morning or evening. If the shutdown fails, complain to the district's Immissionsschutzbehörde, which enforces the permit, not to the operator.
House prices: what the evidence supports
The most cited German study is by the RWI – Leibniz Institute for Economic Research (Ruhr Economic Papers #791, Frondel and others). It analysed almost 3 million ImmoScout24 asking prices from 2007 to 2015. Houses within one kilometre of a turbine were listed on average 7.1% lower; for old houses in rural areas the discount within one kilometre reached up to 23%, while on the edge of towns the effect was barely measurable. Beyond eight to nine kilometres there was none.
These are asking prices, from an era of smaller turbines, and later studies find smaller effects. On a house worth €350,000 without a turbine, 7.1% would be €24,850. Use that as a negotiating reference, not a valuation.
Objecting from abroad
You do not need to be a resident, a citizen or a voter to take part. What you need is to watch the deadlines and write in German.
At the planning stage. Anyone may comment during the public display of a regional or municipal plan draft. Useful comments point to something the planners missed: a house in the outer area left off their settlement map, a protected bird's nest, a valley that carries sound. Once the plan is in force, the remaining route is a judicial review of the plan at the Higher Administrative Court. According to the Federal Administrative Court, an owner whose land lies within the area covered by the contested planning target has standing (BVerwG 4 CN 6/14); the time limit is set by § 47(2) VwGO.
At the permit stage. Turbines over 50 m need a permit under the BImSchG (4th BImSchV, Annex 1 no. 1.6). Smaller wind farms go through the simplified procedure under § 19 BImSchG, without public consultation. A formal procedure with public display under § 10 BImSchG applies if an environmental impact assessment is required or the developer opts for it; several Lower Saxony notices record developers doing so voluntarily. In a formal procedure the deadline for objections is in the public notice. A Thuringia notice from 2025: documents on display 3 April to 2 May 2025, objections by 2 June 2025.
After the permit. Under § 63(1) BImSchG an appeal or lawsuit by a third party against a turbine over 50 m has no suspensive effect: construction may go ahead. An application to the court for interim relief under § 80(5) VwGO must be filed and reasoned within one month (§ 63(2) BImSchG), and an administrative appeal must be reasoned within one month. The first instance is the Higher Administrative Court; in Bavaria the VGH, as the "22 AS" in the 2025 case number shows. Watch the county's public notices so that an approval does not pass you by.
For a buyer abroad this has practical consequences:
- Register for the district's public notices or check them monthly; the one-month periods do not wait for post to reach you.
- Objections in German, with your name and the parcel's address. A short letter that cites the permit file's own numbers (the receptor point, the noise forecast at that point) carries more weight than a long one about the view.
- Proceedings before a Higher Administrative Court need a lawyer. Budget for that before you decide to fight rather than walk away.
- If you are still negotiating, you are not yet the owner. Ask the seller, in writing, whether they will lodge an objection as owner.
If the answer is bad
The plot is within 2H of where a tower could stand. Calculate with the largest turbine realistic for the area, not with an old one already standing. Ask the planning body whether applications have been filed and for which models. Below 2H the visual effect must be assessed individually and a report belongs in the application.
The area is still a draft. Drafts change. In the Region Hannover, an earlier planning stage shown in a 2023 presentation had about 5,672 ha; the adopted plan has about 5,368 ha, some 300 ha less. Note the stage and the date, price in the worst case, or wait for adoption.
A permit procedure is running. Read the noise forecast and shadow calendar for the receptor nearest the house before you sign.
The price no longer fits. Bring the plan stage, the measured distance and, where available, the noise forecast to the negotiation. A certified valuer (Sachverständiger für Immobilienbewertung) can estimate the effect on this house; the RWI average cannot.
The contract. Ask the seller, in writing, whether they know of plans, developer enquiries or lease offers for the plot or neighbouring land. A false answer to a direct question is a different matter from silence. Your notary reads the contract aloud in German; if you need a translation, arrange it before the appointment. More in our guide on buying land from abroad.
You want to build yourself. A new house permitted near an existing wind farm creates a new "permissible residential use", and the authority will check whether it would sit within the noise and shadow levels allowed for homes in the outer area. See building in the outer area.
What the GrundCheck report shows
The GrundCheck report shows, for the plot you mark on the map, the planning layers where they are available digitally, whether it lies in a built-up area or the outer area, protected areas, flood zones and other map layers, each with source and date. It tells you whether a wind energy area from a regional or partial plan lies nearby and how far away. It does not contain a noise forecast, a shadow calculation, a valuation or a legal opinion on whether an objection would succeed, and it is not a land survey.
