Neighbour disputes can affect permission, site access and the ability to continue work. We distinguish public-law objections from private property claims and identify which measures can address the immediate problem.
Separate public and private rights
A neighbour’s objection to a building permit must engage a legally protected position; a general dislike of the project is not enough. Setbacks, consideration for neighbouring uses and particular plan provisions may be relevant. Private-law issues include encroachment, access, support, emissions and boundary arrangements.
A permit does not necessarily resolve private property rights. Conversely, private consent from a neighbour does not replace required public approvals. State neighbour laws can add rules and, in some disputes, preliminary conciliation requirements.
Act on the right timetable
Under section 212a BauGB, a third-party challenge to building approval does not automatically suspend it. Urgent judicial protection may therefore need separate consideration. The time available depends on service, knowledge and the relevant procedural circumstances.
For physical damage, secure a record of the property’s condition before work begins where possible. Construction vibration, excavation and water ingress often require expert evidence to connect the alleged impact with the works.
Create workable access and protection arrangements
A written neighbour agreement can address scaffolding, crane oversailing, temporary access, protective measures, insurance and reinstatement. Define duration, compensation and evidence of pre-existing damage instead of relying on a casual verbal permission.
Four practical examples
Illustrative scenarios: the appropriate steps depend on the contract, evidence and applicable law. These are not reports of client matters.
Scaffolding on neighbouring land
A façade repair needs temporary access. Establish whether there is a statutory entitlement and negotiate practical safeguards.
An excavation threatens a wall
Cracks appear beside a deep excavation. Prioritise safety and evidence, then assess urgent legal protection and responsibility.
A permit is challenged
The developer receives a neighbour’s objection. Check whether separate interim proceedings have been filed and assess the specific protected rights.
Noise from a new use
A commercial unit introduces evening activity. Compare the approved use, operating conditions and actual emissions.
Documents that help us assess your position
Plans, permits, boundary documents, photographs, condition surveys, correspondence, expert findings and dates of service or first knowledge.
Discuss your project or dispute
Tell us where the project is located, who is involved and whether a deadline is approaching. We can then clarify the scope of the proposed engagement and the next steps.
