Right to Light

Right to Light - The right to light (also known as the right to windows) refers to a property owner’s right to have windows and openings in an exterior wall that face the neighboring property. In Germany, there is no general statutory right to light-the right to daylight is not protected as a fundamental right. However, the neighbor law statutes of the federal states and the setback regulations in building codes indirectly regulate the protection of light penetration.

Legal Basis in Bavaria

In Bavaria, the Bavarian Neighbor Law Act (BayNachbG) applies in conjunction with the Bavarian Building Code (BayBO). The setback distances under Art. 6 BayBO indirectly ensure access to light: Buildings must maintain a minimum distance from the property line (typically 0.4 times the building height, at least 3 m). If this distance is maintained, the right to light is generally guaranteed. A separate “right to light” as in England (Right to Light) does not exist in Germany-anyone who maintains the required distance may build, even if the neighbor consequently receives less light.

In contrast to English common law, where a right to light can arise through long-standing possession (Prescription Act 1832), German law does not recognize such a statute of limitations regarding light exposure. This means: In Germany, a neighbor can build right up to the boundary of their setback area at any time without a neighbor who has received light through a window for decades being able to object.

Practical Conflicts

The most common points of contention regarding light rights arise in the following situations:

• Additions and extensions that cast shadows on the neighbor’s existing windows
• Tall hedges and trees that reduce the amount of light (here, the boundary distance rules of the BayNachbG apply)
• Boundary constructions, where a building is constructed directly on the property line
• Photovoltaic systems, which in some cases reflect light and blind neighbors-a special case of immission control

In the case of boundary construction, no windows may generally be installed in the boundary wall-exceptions require the neighbor’s consent. This consent should be secured in the land register as an easement, as verbal consent is not binding on the new neighbor in the event of a change of ownership.

Right to Light through Easement

Even though there is no statutory right to light, a private right to light can be agreed upon as an easement (Section 1018 of the German Civil Code). Such an easement obligates the encumbered property owner to refrain from certain construction measures that would impair the incidence of light on the beneficiary’s property. This easement is entered in Section II of the land register and binds all future owners. Such agreements are particularly common on narrow inner-city properties where access to light is economically valuable-for example, for commercial and retail spaces.

Practical Tip for Property Owners in Nuremberg

We recommend that property owners in the Nuremberg metropolitan region check early on in the planning of construction projects whether setback requirements are being met and whether existing windows on the neighbor’s property could be affected. Especially in densely built-up historic downtown neighborhoods and Wilhelminian-style districts (e.g., Gostenhof, St. Johannis, Maxfeld), lots are narrow, and conflicts over setback distances are common.

When purchasing a property, we recommend checking the land register for registered easements (Section II): Light rights or building restrictions may be recorded there, which can significantly affect the property’s value. An early discussion with the neighbor and coordination with the building authority can prevent lengthy legal disputes. If access to light is important to you-for example, for a sunroom or a rooftop terrace-you should secure this in a contract before purchasing.

Frequently Asked Questions

Can I take action against shading of my windows?

Only if the neighbor violates the setback regulations or building codes. If they comply with the legal setbacks, you have no right to unimpeded sunlight. In the case of illegal structures (built without a permit, too close to the property line), you can request an inspection from the building authority. If the construction is approved and the setback distances have been observed, the only recourse is legal action through civil defense claims in cases of truly unreasonable impairments.

Does my neighbor have to trim their tall hedge if it shades my windows?

The Bavarian Neighbor Act (BayNachbG) regulates setback distances for plants: Hedges over 2 m in height must be at least 2 m away from the property line. If the distance is less than this, you can demand that the hedge be trimmed. However, mere shading caused by a hedge planted in compliance with the rules does not justify a claim for trimming-even if the shading is significant. Exception: For trees, separate distance rules apply depending on the species and height.

Can I install windows in my boundary wall?

In general, no windows may be installed in a boundary wall (directly on the property line). Exceptions are only possible with the neighbor’s consent, which should ideally be secured as an easement in the land registry. Without such security, the neighbor can demand the removal of the windows at any time-even years after installation, as there is no statute of limitations for this claim.

What applies to a new building next to an existing building with windows facing the property line?

If windows were installed in a boundary wall without notarial approval or an easement, a new building on the neighboring property may block these windows, provided it complies with the required setbacks. The existing right to have windows is not protected by grandfathering provisions. Owners with windows near a boundary wall should verify the legal status of these windows and, if necessary, have an easement registered.

How should one proceed when purchasing an existing property with windows near the property line?

When purchasing a property with windows facing the property line, we recommend carefully reviewing the land registry for both properties before the purchase. Easements are recorded in Section II of the land registry-this section indicates whether a right to light exists in favor of the property being purchased or, conversely, whether a building encumbrance burdens the neighboring property. If no such entry exists and the windows are located in the boundary wall or very close to the boundary, there is a risk that a future new building on the neighboring property could permanently obstruct the light. In Nuremberg’s Old Town and the Wilhelminian-style neighborhoods, buildings are often constructed adjacent to one another without sufficient clearance-here, a review of the legal situation is particularly important. We recommend reviewing the building’s site report and building permit documents at the city archives or the building authority to clarify the historical approval status of the windows. This research costs little but can reveal significant risks when purchasing an existing property in the city center.
