Can I build a fence on the boundary in Finland?
On your own side yes — on the line only with the neighbour. A hedge or low fence entirely on your side usually needs no permits within the building ordinance (typically up to 1.2–1.6 m). A fence exactly on the boundary is a joint project: it needs the neighbour's consent, with costs and upkeep shared by default. Tall, solid or streetscape-affecting fences often require an action permit.
📋 The rules
- An ordinary fence fully on your own side is usually free — the ordinance sets height and material limits (often ~1.2–1.6 m without a permit).
- A fence on the boundary requires the neighbour's consent — on the line it's shared, with shared upkeep.
- Tall fences, walls and street-side fences often need an action permit — and zoning can dictate the fence type.
- Sight areas at junctions must stay clear — traffic safety overrides fence wishes.
- Plant hedges so they don't spread over the boundary when grown — overhanging branches and roots fall under the Neighbour Relations Act.
🔓 Exceptions
- Temporary light structures (a low mesh fence for a vegetable patch) are effectively free.
- Noise barriers and retaining walls are structures assessed separately.
⚠️ Penalties
An unpermitted or plan-violating fence can be ordered lowered or removed. Boundary-fence feuds are the evergreen of neighbour disputes — a written agreement beats the district court.

❓ Frequently asked questions
How tall a fence without a permit?
Municipal — the typical ordinance line is 1.2–1.6 metres on your own side. Taller usually needs an action permit.
Do I need consent for a fence on my own side?
No — fully on your side it's your business within the ordinance. On the boundary, consent is required.
Who pays for a boundary fence?
By default the neighbours together when it serves both — agree in writing before building.
Can the neighbour demolish a shared fence?
Not unilaterally — a boundary fence is joint property. Disputes resolve by agreement or ultimately in court.
