Windbreaks on the Balcony: What's Allowed? – State-by-State Comparison 2026

Finally spring – and the balcony is calling. But those who want to install a windbreak quickly encounter uncertainty: Do I need a permit? What am I even allowed to do as a tenant? And what do the building regulations in Bavaria, North Rhine-Westphalia, or Berlin say about this? This guide gives you clear, state-specific answers – so you can enjoy your balcony relaxed and legally compliant.

The most important thing first: Whether a windbreak is allowed on the balcony depends on three factors: the type of attachment (mobile or fixed), your status as a tenant or owner, and the respective regulations of your federal state. In this article, we show you the right solution for every constellation.

1. Windbreak vs. Privacy Screen: What's the Difference?

In everyday language, the terms "windbreak" and "privacy screen" are often used synonymously – however, legally and technically there is an important difference:

•       Windbreak: Windbreak

•       A windbreak primarily functions to keep out wind and weather. Typical materials are ESG glass, Plexiglas, aluminum slats, or durable outdoor fabrics.

•       Privacy screen: Privacy screen

•       A privacy screen is intended to keep out prying eyes. Bamboo mats, polyrattan panels, or fabric coverings are typical here.

Crucial for the legal situation is not the name, but the question: Is it a structural alteration? This distinction determines whether a permit from the landlord, the homeowners' association, or even the building authority is required.

2. Tenant vs. Owner: Who is Allowed to Do What?

The initial situation is fundamentally different for tenants and owners. Here's a clear overview:

What Do Courts Say About This?

Case law has dealt with the issue in several rulings:

•       AG Hamburg-Barmbek (Az. 811b C 366/09): Attaching a bamboo mat to the balcony railing with cable ties is permitted contractual use – no landlord approval necessary.

•       LG Frankfurt am Main (Az. 2-13 S 127/12): The installation of Plexiglas panes as a windbreak, permanently connected to the balcony, is a structural alteration and requires the landlord's consent.

•       AG Cologne (Az. 48 C 2357/01): A privacy screen that is no higher than the balcony railing and visually matches the facade may also be installed without landlord permission.

3. The Federal States Comparison 2026: What Applies Where?

Building regulations in Germany are a matter for the federal states – this means that a windbreak that is permit-free in NRW may require a full building application in Berlin. Below you will find an overview of the most important regulations in the most populous federal states.

What do "permit-free" vs. "approval-free" mean?

Many builders confuse these two terms – with expensive consequences:

•       Permit-free (Verfahrensfrei) means: The official review process is omitted or simplified. But: The structure must still meet all legal requirements (statics, fire protection, boundary distances).

•       Approval-free (vollständig genehmigungsfrei) means: In most federal states, this effectively does not exist for structural interventions in buildings.

4. What does "approval-free" mean? The distinction between mobile vs. fixed

The core question is always: Does the measure involve an intervention in the building structure? Here is a practical decision matrix:

5. Permissible height: What do courts and building regulations say?

The height of the windbreak is a particularly common point of contention – both with neighbours and with landlords.

•       Balcony privacy screen up to railing height (approx. 90-110 cm): Usually permitted without approval.

•       Privacy screen above railing height: Generally considered a structural change; landlord's consent or owners' association resolution required.

•       Windbreak in the garden/terrace: Here, the fencing rules of the federal states and municipal statutes apply. The typical permissible height without approval is 1.80-2.00 m, but this varies greatly.

•       Boundary distance: Generally at least 3 m from the neighbouring property boundary, unless a valid development plan specifies otherwise.

For optimal effectiveness, research recommends a height of 1.80 to 2.00 m for a terrace windbreak to fully protect a seated outdoor area from wind. This is also the limit at which a permit requirement applies in many federal states – a tension that significantly influences purchasing decisions.

6. Windbreaks in the owners' association (WEG)

If you own a condominium, you live in a special legal world. The balcony belongs to the common property – even if you use it alone.

§ 20 WEG (new since 2020): Structural changes to common property generally require a resolution by the owners' assembly. Since the WEG reform in 2020, a resolution can be passed by a simple majority – previously, unanimity was required.

If the windbreak changes the overall visual impression of the property or negatively affects uniformity, there is already an impairment that requires the consent of all negatively affected parties.

8. Frequently Asked Questions (FAQ)

Can I install a windbreak as a tenant without permission?

Yes, provided it is a mobile, non-invasive solution that does not require drilling and does not significantly exceed the railing height. Bamboo mats, clamping panels, or freestanding windbreaks are generally unproblematic. Permanently screwed solutions always require the landlord's written permission.

From what height does a windbreak require approval?

This varies depending on the federal state and building regulations. As a rule of thumb: Above railing height (approx. 1.10 m) on the balcony, landlord permission is required. For freestanding structures in the garden or on the terrace, the limit is often 1.80–2.00 m, after which a permit is required in many states.

What is the difference between “verfahrensfrei” (exempt from procedure) and “genehmigungsfrei” (exempt from approval)?

“Verfahrensfrei” means that the official review procedure is waived or simplified – but not that all building regulations are suspended. “Completely genehmigungsfrei” in the sense of “anything goes” is practically non-existent in Germany for fixed structural changes to a building.

Can my landlord prohibit my privacy screen?

If the privacy screen extends beyond the railing height, negatively alters the exterior appearance of the house, or risks structural damage: yes. For simple, non-invasive mats up to railing height, the landlord usually has no right to prohibit them – as long as the overall appearance of the house is not impaired (AG Köln).

Do I always need a permit in Berlin?

For fixed structural installations: yes. Berlin is one of the strictest federal states. Plan at least 3–4 months in advance. For mobile windbreak solutions that do not interfere with the building structure, the same tenancy law rules apply as everywhere else.

Are there windbreak solutions that I, as a tenant, can install without any permission?

Yes. Freestanding windbreaks with their own base, mobile screen systems, or hedges planted in pots require neither official approval nor the landlord's permission, as long as they do not touch the building structure and do not extend beyond the top edge of the balcony railing.

9. Conclusion: Relaxed and legally compliant – here's how

The desire for a sheltered, cozy balcony is absolutely justified – and in most cases, it can be realized with simple, permit-free solutions. Here are the most important points to remember:

•       Tenants: Opt for mobile, clamp-on or tie-based windbreak solutions up to railing height – these are possible nationwide without permission.

•       Owners (condominium): Obtain a WEG (condominium owners' association) resolution before drilling. The 2020 WEG reform has significantly simplified this.

•       Homeowners: Check the specific state building code for structures over 2 m high. Use the building authority as a consulting body, not just an approval authority.

•       State differences: Especially in Berlin and Hamburg, plan early; in North Rhine-Westphalia and Lower Saxony, owners are comparatively flexible.

The best windbreak solution is always one that offers maximum protection, is legally sound, and is visually appealing. Our range offers the right answer for every situation – from uncomplicated clamp-on bamboo mats for tenants to high-quality toughened glass systems for demanding terrace owners.
