Can I build a fence on the boundary in Austria?
Yes — but against the boundary on your own land, not on the line. A fence (Einfriedung) goes on your own land against the boundary; a fence exactly on the line uses the neighbour's ground and needs their consent. The permit and height limits are provincial: many provinces allow fences up to ~1.5 m permit-free, Burgenland up to 1.80 m notification-free, Vienna up to 2.50 m without a permit, Tirol usually with notification from ~2 m. The Civil Code sets a right-hand fencing duty (§ 858): each owner is responsible for the fence on their right-hand side (viewed from the street). A boundary fence in co-ownership is maintained jointly. In short: yes on your own land, height by province.
📋 The rules
- Fence against the boundary on your own land
- On the line only with the neighbour's consent
- Permit/height are provincial
- Often up to ~1.5 m permit-free (Vienna 2.5 m)
- Civil Code § 858: right-hand fencing duty
🔓 Exceptions
- Boundary fence in co-ownership: costs shared
- Development plan/townscape rules can be stricter
- Corner/sightline rules can limit the height
⚠️ Penalties & fines
Building over the line without consent is an interference with property — the neighbour can demand removal (civil). Exceeding the height without the required notification/permit is an administrative offence under the provincial building code, with fines that vary by province. Beware a myth: "I can build any fence I want as long as it's on my side" is not quite right — height limits and permit thresholds vary by province, and corner, sightline and townscape rules can restrict you even fully on your own ground. Tip: ask the municipality before building and agree with the neighbour.

❓ Frequently asked
Can I build a fence on the boundary?
Yes, but against the boundary on your own land, not on the boundary line itself. A fence exactly on the line also uses the neighbour's ground and so needs the neighbour's consent. On your own land you may generally build right up to the boundary.
How high can the fence be?
It depends on the province, because the building code is provincial. Many provinces allow fences up to about 1.5 metres permit-free, Burgenland up to 1.80 metres notification-free, and Vienna up to 2.50 metres without a permit. In Tirol a notification is usually needed from around 2 metres.
Who pays for the boundary fence?
The Civil Code, in § 858, sets a right-hand fencing duty: each owner is responsible for the fence on their right-hand side, viewed from the street, which then belongs to them alone. A fence built jointly on the line is co-owned, and maintenance costs are shared.
Do I need the neighbour's consent?
For a fence on your own land, generally not. But if you want to place the fence exactly on the boundary line, you need the neighbour's consent, because you're using their ground too. An existing boundary fence in co-ownership may not be removed or altered unilaterally.
What happens with a too-high fence?
If you exceed the permitted height without the required notification or permit, that's an administrative offence under the provincial building code, with fines that vary by province. If you build over the line, the neighbour can demand removal under civil law.
