Neighbour's objection against construction of planned residential buildings fails before the Administrative Court Schleswig – no violation of subjective rights was apparent.

A neighbour's objection against a building permit has prospects of success only if the neighbours' own rights are violated with a preponderance of probability.

The conflict over neighbour rights in large-scale projects

Time and again it occurs in practice that neighbours proceed with a neighbour's objection against a granted building permit. Particularly in larger construction projects – such as the construction of residential buildings – residents fear overloading of the area, noise, overshadowing or unreasonable possibilities of overlooking. But what chances do neighbours actually have of being successful with an objection against a building permit?

The Administrative Court Schleswig (order of 23.09.2025, Az. 2 B 13/25) recently had to deal with such a case. Neighbours wanted to stop the construction of three residential buildings with a total of 36 units and 72 parking spaces by means of a neighbour's objection. However, their application for suspension of the legal effect of the objection was rejected.

The facts: Neighbour's objection against three residential buildings and 72 parking spaces

The building authority had granted a building permit for three residential buildings on 21 July 2025. The planned buildings were to comprise 36 apartments as well as 72 parking spaces. The affected neighbours filed an objection and applied to the Administrative Court to suspend the immediate enforcement.

Their arguments:

• Violation of setback distances (§ 6 LBO)
• Incompatibility with the area structure (right to preservation of area character)
• Unreasonable possibilities of overlooking from balconies onto their property
• Increased traffic and noise pollution caused by the large number of parking spaces

The applicants considered themselves to be in violation of their neighbour rights and wanted a judicial clarification in summary proceedings.

The legal starting point: interest in realizing construction takes precedence

The central basis of the proceedings is § 212a BauGB: According to this, an objection and a claim for annulment against a building permit have no suspensive effect. The legislator has thus deliberately given priority to the interest in realizing construction.

The court can order suspension of legal effect only as an exception if with a preponderance of probability a violation of neighbour-protecting norms is present. What is decisive is therefore not the objective unlawfulness of the permit, but solely the question of whether the neighbours are affected in their subjective public neighbour rights.

Setback distances: No violation apparent

The applicants had objected to an underobservance of the setback distances. The Administrative Court established, however, that the setback distances were preserved. Neither the construction documents nor the site plans revealed any violations of § 6 LBO. Furthermore, the question of setback distances was not a subject matter of examination in the simplified building permit procedure (§ 63 LBO) in any event.

Central statement: A neighbour can rely on setback distances only if these are concretely violated to his detriment. That was not the case here.

Right to preservation of area character: Residential buildings are "residential use"

The applicants furthermore referred to a right to preservation of area character. They argued that the planned buildings did not fit into the existing surrounding development.

The court made clear: The Building Use Regulation (BauNVO) does not distinguish between single-family, semi-detached or multi-family houses. The use type is solely "residential". Multi-family houses are therefore permitted in the general residential area.

Key Finding: Neighbours have no entitlement to the preservation of a specific building typology (for example, only single-family homes).

Duty of consideration: No unreasonable impairment

Particular weight was attached to the applicants' submissions regarding sight lines. They feared being watched from the balconies of the new buildings as if from an "observation tower".

The court rejected this. Sight lines are part of everyday life in urban areas and must generally be accepted. No special protection beyond the setback areas exists. The court could also not identify a "prison courtyard situation" or "oppressive effect". The buildings complied with the setback requirements, and moreover green spaces and trees remained as visual screening.

Key Finding: The duty of consideration (§ 34 BauGB) is only breached when the situation becomes unbearable and unreasonable for the neighbour. The mere feeling of being watched more closely is insufficient.

Parking spaces and traffic: Noise must be tolerated

The increased number of parking spaces also did not result in a violation of neighbour's rights in the court's view. Although traffic volume increases significantly, parking and driving movements are typically part of residential use and are permissible even in purely residential areas (§ 12 BauNVO).

The planned location of the access routes and the screening effect of the buildings ensured that no unreasonable noise pollution would affect the neighbouring property.

Key Finding: Even a significant increase in parking lot traffic is generally tolerable in residential areas.

Conclusion: Clear strengthening of the builder's interest

With this ruling, the Administrative Court of Schleswig (Verwaltungsgericht Schleswig) has once again emphasised that neighbour objections to building permits are only successful in exceptional cases. What is decisive is whether a concrete violation of neighbour-protecting provisions exists. Merely subjective disadvantages – such as sight lines or altered area characteristics – are insufficient.

Recommendation for neighbours

Anyone considering a neighbour objection should examine early on whether concrete violations of setback requirements, the duty of consideration, or incompatibility with the area exist. Mere dissatisfaction with densification is insufficient.

Recommendation for builders

For builders, this decision represents a clear confirmation of building security": With a properly issued building permit, construction can regularly proceed despite neighbour objections. It remains important to comply with lawful planning whilst observing all setback and planning requirements.

It is important for all parties involved that the approval situation for a (larger) project is assessed realistically from a legal perspective in order to successfully defend one's own position or to challenge an already approved project – for example, with a neighbour objection.
