A Trampoline in the Garden: What Cologne Neighbors Actually Have to Tolerate

The Official Rule

A garden trampoline between two Cologne neighbors sits under German neighbor law, not tenancy law, and the operative rule is § 906 BGB. It lets a property owner block noise, vibration, and similar effects from next door only when they amount to a wesentliche Beeinträchtigung, a substantial impairment of their own use of the property; anything short of that has to be tolerated. The Bundesgerichtshof has applied and re-applied the same working definition of that line for decades: whether a sensible, reasonable person would find the interference acceptable once the interests on both sides are properly weighed, not a fixed decibel number (BGH, 27 November 2020, Az. V ZR 121/19). When a neighbor does clear that bar, the actual legal tool for making them stop or move something is a separate paragraph, § 1004 BGB, the general removal-and-injunction claim German property law runs on.

Children’s play noise carries an extra layer of protection on top of that general test, though it applies more narrowly than people often assume. Paragraph 22 Absatz 1a of the Bundesimmissionsschutzgesetz (BImSchG), added by a 2011 amendment, states that noise from facilities, Kindertageseinrichtungen, Kinderspielplätze, and similar setups, caused by children under 14, generally isn’t a harmful environmental impact at all. Read literally, that covers a Kita or a public playground, not one family’s own backyard trampoline. But the Bundesgerichtshof closed that gap in a Hamburg case about a school’s Bolzplatz: it ruled that this provision’s underlying policy judgment, that ordinary children’s noise deserves broad tolerance, radiates outward into how German civil courts assess child noise generally, including in tenancy disputes that fall outside the statute’s literal wording (BGH, 29 April 2015, Az. VIII ZR 197/14). That same ruling is also the clearest statement of the privilege’s actual boundary: it protects children under 14, the same line German youth-welfare law draws between a Kind and a Jugendlicher, and it does not extend to older kids or teenagers using equipment loudly, especially outside permitted hours.

Cologne’s own courts have already ruled on the neighboring question of timing, and the pattern is worth knowing. In 2006, the Amtsgericht Köln reduced a tenant’s rent by 10 percent because noise from an adjacent playground kept running past 7pm, into what the court treated as the start of protected evening rest, even though the same playground’s ordinary daytime noise was accepted as foreseeable and not a defect at all (AG Köln, Az. 205 C 407/05). The case wasn’t about a garden trampoline specifically, but the underlying logic transfers cleanly: it’s rarely the existence of outdoor play noise that gets a Cologne court’s attention, it’s whether that noise keeps running once the evening quiet-hour window starts.

On physical distance from the boundary, Cologne genuinely differs from Berlin. North Rhine-Westphalia’s own Nachbarrechtsgesetz (NachbG NRW) sets a real formula in its § 31 for “sonstige mit dem Grundstück nicht fest verbundene Anlagen”, movable structures not permanently attached to the ground, that stand over 2 meters tall: a minimum 0.50-meter clearance from the property line, plus however much the structure’s height exceeds that 2-meter mark. Applied to a typical family trampoline with a 2.80-meter safety net, that formula alone would call for roughly 1.30 meters of clearance. No published Cologne or NRW court ruling has confirmed that a trampoline actually counts as this kind of “Anlage” under NRW’s own wording, but a nearly identical clause exists in Brandenburg’s Nachbarrechtsgesetz, and a real 2024 case shows exactly how a court there answered that question: the trampoline in front of it was found to be such a structure, and its owners were ordered to move it roughly 1.80 meters back from the line, based on Brandenburg’s own 1.50-meter threshold rather than NRW’s 2-meter one (OLG Brandenburg, Az. 5 U 140/23). The same ruling still refused the neighbors’ request for the trampoline’s complete removal or a ban on jumping, calling its use in a private garden sozialadäquat.

What Real People Say

Cologne’s mix of dense Gründerzeit blocks and quieter house-and-garden districts means a trampoline dispute here tends to follow a fairly predictable arc: a neighbor’s first complaint is usually broad, remove it, get rid of it, before narrowing down to something a court would actually take seriously. AG Köln’s own 2006 ruling is a useful illustration of where that narrowing tends to land, the court had no trouble accepting that a playground next door meant foreseeable daytime noise, and only sided with the tenant once the noise kept running into the evening rest period the Hausordnung and general quiet-hour expectations are built around.

Families in Cologne’s own garden-heavy districts describe a similar pattern once an actual dispute starts: neighbors rarely object to the trampoline’s mere existence for long, because that argument doesn’t hold up, but timing complaints about early evenings or weekend mornings do get taken more seriously, both by the neighbor raising them and, if it ever gets that far, by a court. The distance question causes its own confusion locally, since NRW’s own law does set a real figure unlike Berlin’s, a detail that surprises people who assumed, wrongly, that trampolines simply fall outside any German distance rule everywhere.

Step by Step

1. Know that ordinary trampoline use in your own garden doesn’t need permission and can’t be banned outright, German courts consistently treat it as sozialadäquat, normal family life.
2. Check NRW’s own § 31 NachbG NRW distance formula for your setup, unlike Berlin, North Rhine-Westphalia has a real distance rule for movable garden structures taller than 2 meters, and it’s worth doing the math for your own trampoline’s height rather than assuming it doesn’t apply.
3. Don’t borrow Brandenburg’s 1.80-meter figure directly, that number comes from Brandenburg’s own 1.50-meter threshold, not NRW’s 2-meter one, so your own required clearance under NachbG NRW will come out differently.
4. Keep trampoline use to ordinary daytime hours, avoiding the evening quiet-hour window and nighttime, Cologne’s own courts have already shown that timing, not the noise itself, is what actually moves a case.
5. Remember the child-noise privilege has a real age boundary, it’s built around children under 14, not teenagers, so a dispute involving older kids using equipment loudly, especially late, sits on different legal footing than a younger child’s daytime play.
6. Have the short, friendly conversation with neighbors regardless, mentioning roughly where the trampoline will sit and when your kids are likely to use it costs little and heads off most disputes before they start.

Compliance Note

This page explains the general legal framework around garden trampolines, neighbor law, and outdoor play noise under German federal law and North Rhine-Westphalia’s own Nachbarrechtsgesetz, but it is not legal advice, and how these rules apply can depend on the specific facts of your property and situation. For your own case, consult a lawyer specializing in Nachbarrecht (neighbor law) or contact your local Bauamt.
